June 14, 2017, Deerfield, Mass. - Peter Melnik, a fourth generation dairy farmer from Deerfield, Massachusetts, is a firm believer a farm should be economically and environmentally sustainable. This belief started him on a 10-year search for a way to make an anaerobic digester work on his farm.

"At first I thought I could build a small digester to produce enough electricity for my farm," Melnick said. "Then the concept of food waste was introduced to me and the story just grows from there."

The recent announcement of an alliance between Dairy Farmers of America and Vanguard Renewables, a Massachusetts-based renewable energy developer, was the missing piece of the puzzle for Melnik. READ MORE

Last month Statistics Canada released the results of the 2016 Census of Agriculture. Like many of you, I was eager to read up on the results and discover how our industry has changed in the five years since the last survey was conducted.

Some findings, such as the edging up of the average age of farm operators from 54 in 2011 to 55 in 2016, aren't all that surprising. After all, aging is a fact of life. Other findings, however, gave me pause. For example, Statistics Canada found that even though the average age of farmers has increased, only one in 12 operations have a formal succession plan outlining how the farm will be transferred to the next generation.

In other words, the vast majority of Canada's farm operators have not taken steps to safeguard the businesses they've worked long and hard to build.

Experts in the field agree there are many reasons farmers shy away from succession planning, including fear: fear of change, of creating conflict within the family, of losing one's identity as a farmer, and of confronting the fact that not even the healthiest among us live forever. Then there's the time required to craft a plan and implement it when there are still animals to feed, seeds to plant and suppliers and customers to work with, plus all the other tasks that contribute to a farm's long-term success. Perhaps one of the most significant barriers, though, is the daunting scope of work the term "succession planning" entails.

Though we can't do that work for you, the editorial teams behind Agrobiomass, Canadian Poultry, Fruit & Vegetable, Manure Manager, Potatoes in Canada and Top Crop Manager have partnered to help ease the way with our first annual Succession Planning Week.

From June 12 to 16, we'll be delivering a daily e-newsletter straight to your inbox, packed with information and resources to help you with succession planning in your operation. Each e-newsletter will offer practical advice and suggestions you can use, whether you're an experienced farm owner wondering if your succession plan needs some tweaking or an aspiring successor wondering how to start the succession conversation.

But that's not the only conversation we want to kick-start. Share your succession planning tips and success stories on Twitter and Facebook using the hashtag #AgSuccessionWeek. The best of the best will be published on our website ( and included in Friday's e-newsletter.

We hope Succession Planning Week offers valuable information to help you keep your operation growing, now and for generations to come.

June 8, 2017, Linn, Kan. - Handling manure can be costly. A farm in Kansas was spending up to $90,000 each year to pick up manure solids, but now the costs have dropped significantly.

Since November of 2000, Lee Holtmeier has been managing the Linn Willow Creek Dairy LLC outside Linn, Kan. Prior to that, he'd worked 20 years for Farmland Foods buying hogs and grew up auctioneering cattle and hogs at his family's sale barn business in Nebraska. The only experience he'd had with dairy cows is when he started breeding cattle for Willow Creek Dairy when the dairy began operations in 1999.

While he didn't know some of the intricacies of dairy farming, Holtmeier did know how to manage people and spot problems. "We've changed a lot of things and moved some things around," Holtmeier says of his time at the farm the past 17 years.

One of those major changes was improving how manure was handled. Prior to 2007, the dairy was spending anywhere from $80,000 to $90,000 per year hiring dump trucks and excavators to take out the manure solids from three settling bays and three lagoons in the spring and fall. Not only was it costly, it also had a larger environmental footprint with several heavy machines being run to pick up manure. READ MORE

May 31, 2017, Orange County, Cali. - In the "Back to the Future" film franchise trilogy, Dr. Emmet Brown replaced the plutonium-based nuclear generator in the De Lorean time machine with a "Mr. Fusion" generator from the future that uses garbage as fuel.

CR & R Environmental Services has a similar dream for the future – turning waste into energy through an advanced technology called anaerobic digestion. Anaerobic digestion produces "biogas" from organic waste in a zero waste, 100 percent renewable process.

At a recent Economic Workforce Development Committee luncheon hosted by the Lake Elsinore Chamber of Commerce at the Diamond Club at Storm Stadium, Alex Braicovich, senior regional vice president at CR & R, shared the vision, the process and the progress of their initiative of "Turning Today's Waste into Tomorrow's Energy."

CR & R, a full service, privately held, integrated waste management company based in Orange County, California, was founded in 1963 with one truck in a waste-hauling operation and later added two recycling trucks.

Today, the company has grown to include 50 municipal contracts in Southern California and southwestern United States.

They have 12 processing contracts and utilize 1,000 trucks every day with 1,600 employees that serve 2.5 million residential customers and 50,000 commercial customers. They have two solid waste facilities, five transfer stations and two landfills – a large one in Yuma, Arizona, and a smaller one serving Catalina Island.

The company has always been on the leading edge, including having the first recycling buy-back center in Orange County, the first three-can, fully automated curbside collection system, the first network of Material Recovery Facilities and one of the first bio-filtration systems. READ MORE

May 10, 2017, Bonduel, WI – While AgSource Laboratories is not "older than dirt," the organization does have a 50-year history of analyzing soil and contributing to the overall health and productivity of thousands of acres of land.

What started as a county extension milk lab has grown into a full service agronomy lab, complete with nutrient management planning and GPS soil sampling services.

AgSource Laboratories, in Bonduel, Wis., became a part of AgSource (then called ARC, Agricultural Records Cooperative) in August 1967. That first year, the lab processed just 5,301 soil samples. Today, the lab can analyze that many samples in under two days.

"We're very proud of the lab's long history," notes Steve Peterson, AgSource Vice President of Laboratory Services. "Bonduel has been a great community to work in. Thank you to our friends in Bonduel and thank you to our customers for 50 terrific years!"

Over the years, the laboratory has specialized in forage, soil, plant tissue and manure testing. While forage testing is no longer offered, agronomy services have expanded to include VRT fertilizer recommendations, GPS soil sampling and nutrient management planning.

"Every day in the lab is different, which keeps things fun," comments Peterson. "It should be interesting to see how we continue to adapt and grow in the future."

AgSource Laboratories, in Bonduel, Wis., will officially celebrate 50 years of soil testing services this August 2017. Customers, friends and community members are welcome to attend several special events this summer at the laboratory, located at 106 North Cecil Street. Stay tuned for more fun, 50th celebration announcements.

North Carolina has long been a major pork-producing state, with the industry providing well over 50,000 full-time direct and indirect jobs. However, being the second largest pork-producing state in the U.S. means that North Carolina must contend with mind-bending amounts of swine manure and associated ammonia. The 2.3-plus million pigs housed in more than 2,000 facilities produce so much waste that the state government has mandated the conversion of manure
into energy.

That means biodigesters. But which digester designs might be best to address the situation? Shlomi Palas believes he has found the best technology to handle North Carolina’s serious swine manure problem.

“There have been some biogas plant designs tried by other parties in this state, but we believe we have found the right solution,” says Palas, CEO of Charlotte, NC-based Blue Sphere Corporation.

Blue Sphere has operated for more than two decades and has facilities in several countries, including Italy, the UK, and now Holland and the U.S. The firm oversees entire waste-to-energy facilities, choosing appropriate technologies from well-established contractors and arranging to generate and sell electricity, scrubbed biogas, organic fertilizer, compost and other valuable products.

Electricity production at Blue Sphere’s $20-million, 3.2-MW food waste biogas facility in Johnston, RI, will be connected to the grid in that state by March. Its $27-million, 5.2-MW food waste facility in Charlotte began supplying electricity to Duke Energy in mid-November 2016, with full commissioning and feedstock ramp-up occurring over the next few months.  

After almost two years of researching the most suitable technologies for hog manure, Blue Sphere feels it has succeeded in finding the best, most-efficient systems for its two new digester facilities under development in North Carolina.

Palas says they are confident in the chosen vendors for several important reasons.

“The technology providers have long-proven experience and track records of many installations in swine manure processing, and their technologies are working 100 percent,” he reports. “While American hog manure has a little more liquid than European hog manure, the combination of the U.S. and Europe technologies will have the appropriate adaptations to be successful with us here, and the companies involve have also provided us with financial assurances.”

European hog manure has about two to three percent solids, but due to feeding regime differences, American hog manure contains one to 1.5 percent solids.

Removal of liquid from the hog manure will be done onsite at individual farms using a combination of technologies. Again, Palas says these sorts of separation system are new to North America, but are working well in Europe and have been successfully tailored for U.S. swine manure.

“Transporting liquid is very costly, so the need to pre-treat on site is critical,” he notes. “We bring the manure dry matter up to 20 to 30 percent and then transport it to the digester.”

Once fully operational, the new NC facilities will produce an annual revenue of about $10 million [estimated] from renewable energy. However, while the biogas from both the Charlotte and Rhode Island projects is being used to generate electricity, Palas foresees a significant shift coming and so the hog manure biogas may be used differently.

“There is a change going on in the gas market, from electricity production to production of bio-methane, compressed natural gas and liquefied biogas for vehicles,” he says. “The engines that use this gas are already well-developed and already many Fortune 500 countries use trucks and cars that run on this fuel.”

Blue Sphere is developing other sites in North Carolina and worldwide, and Palas attributes his firm’s success to many factors, chief among them is an ‘agnosticism’ to digester technologies.

“The biggest mistake that other firms have made, and are still making, is that they get stuck with specific systems,” he explains. “We are open to using tech from Italy, Canada, Germany, China, Japan, United States and other parts of the world to find the best fit for the feedstock we have. We focus on the waste first. We actually have a dedicated staff member to find and keep up with technologies from all over the world. But no matter the technology, the systems must be bankable and well-established so that we can obtain funding and build a project successfully. We cannot work with startup technology.”

Having said that, Blue Sphere cannot handle North Carolina’s colossal swine manure problem alone, and the company is strongly encouraging other renewable energy players to participate.

“The process begins with permits, site selection, establishing a market for the gas and so on, and that can take over a year,” Palas explains. “Construction can take another 12 to 18 months. We have every intention of being a primary player, but due to the timelines involved, we cannot do it alone, and we are inviting others to get involved in this serious challenge. Hog manure is a huge market.

“We are starting with these two food waste digester projects and will make sure they are running well,” he adds. “Once we have proved our solution is workable, we’ll know we have a winner and then we can go across the country.”

In January, Blue Sphere also held some meetings in Canada, so stay tuned for developments north of the border as well.

For Eric TeVelde, owner of Open Sky Ranch Dairy near Riverdale, Calif., the business case to purchase a deeply discounted, mothballed, but structurally sound anaerobic digester on his newly-acquired farm was just too good to ignore.

TeVelde, who purchased the Central Valley dairy in 2012, now operates five, free-stall milking barns on the farm with about 4,500 milk cows. They have an additional 4,500 dry cows and replacement cattle in what is one of the largest dairy farms in Fresno County. TeVelde and his family had been dairy farming in the Central Valley for generations.

The dairy operates a closed flush manure management system where barns are flushed clean with water two to three times a day. This generates about 30 million gallons of liquid manure annually. The manure and waste water mix is transported through a storage and piping system, eventually being pumped into one of several nearby lagoons, which all told have a holding capacity of about 100 million gallons.

The dairy farms about 1,500 acres, primarily growing feed for their cows. Prior to the restart of the anaerobic digester, the raw manure was processed through a US Farm Systems-brand solid separator, with the liquid manure continuing on to the lagoons and the solids reused as bedding. TeVelde says the liquid manure was sold or land applied on the dairy’s cropland as organic fertilizer.

It is this approach to manure management that concerned state legislators because of the amount of methane released by storing the raw liquid manure. By treating the manure through an anaerobic digester prior to land application, this removes the methane while retaining all of the other beneficial nutrients, which is why the state is financially supporting this approach to manure management to help reach its methane emissions reduction target. The Environmental Protection Agency (EPA) says that methane emissions have 25 times greater impact on climate change than carbon dioxide over a 100-year period.

The decommissioned anaerobic digester and the accompanying biogas management technology that TeVelde purchased was situated on the Open Sky Ranch Dairy property. After talking to other dairy farmers who had installed anaerobic digesters and working with California-based biogas power developer, Maas Energy Works (MEW), TeVelde recognized the potential of refurbishing the facility and using the biogas for power production. He decided to purchase the installation in 2015.

In California, an anaerobic digester is often a lined, underground, covered lagoon where biologically-rich waste material – like liquid manure – is collected and retained over a specified time period. The microbes within the manure in the oxygen-free environment generate methane, which can be captured, scrubbed, and used as fuel, with the liquid and solid by-products still available for organic fertilizer or cow bedding.

California, the largest milk-producing state in the U.S., announced last November that it wants its dairies and other livestock operations to reduce methane emissions by 40 percent below 2013 levels by 2030. The regulations currently in development will take effect in 2024.

TeVelde says his purchase of the digester was not in response to this specific regulation, but he definitely was anticipating that the dairy industry was on legislators’ radar.

A state grant to cover nearly half the $2 million cost of redesigning and refurbishing Open Sky’s digester helped to sweeten the deal. It was a $973,000 matching grant under the California Department of Food and Agriculture’s Dairy Digester Research and Development Program. In July 2015, the department distributed grants totaling $11.1 million to five dairy digester projects from the program.

What gave TeVelde further assurance that his biogas recovery and power generation system would succeed where the previous owner had failed was working with Maas Energy Works. MEW already had nine biogas recovery and power generation systems working on dairies throughout the western U.S. Once they sat down and crunched the numbers, TeVelde could see the business sense in purchasing the digester and pursuing the redesign project, with the government grant support.

The biogas recovery and power generation system designed and built by MEW and owned by the dairy came on line last August. The dairy looks after day-to-day operations, with ongoing and contracted monitoring by MEW.

“What the dairy has contracted with us to do is that we monitor the equipment 24/7 and control the equipment from our control centre in our office,” says Daryl Maas, owner of MEW. “We do all the parts ordering, calibration of the equipment and all the maintenance check list.”

TeVelde says he and a hired contractor look after what needs to be done to maintain the digester and power generating system, with direction provided by MEW. The contractor looks after such details as regular oil changes on the engine powering the generator and any other maintenance requirements.

“The maintenance list provided by Maas Energy is not very extensive, and if I miss one day, it’s not the end of the world,” says TeVelde. “I just want to make sure everything is working properly.”

So far, he has found the system manageable and functioning as advertised, and is anxious to see how well it performs over the next five to 10 years.

He says the power generated by the 800 kilowatt (kW) system replaces all of the dairy’s power consumption, and estimates that with saving of about $500,000 per year, the system should pay for itself within five years.

In fact, the system is generating more biogas than the current power generator can consume. California restricts power generation from a single generator to offset the dairy’s own power bill and using the same system to sell excess production. So the dairy is seriously considering installation of a second power generator, using the excess biogas currently being flared to produce power to sell to the grid.

Restarting the digester has not caused a major disruption in manure flow at the dairy. Maas says the company’s goal is to take a plug-in approach to work within the existing manure management system.

He describes the Open Sky Ranch Dairy redesign and refurbishing project as unusual, because the biogas produced by the previous system owner was not used as fuel for power production. The goal of the old system was to capture the biogas, scrub it, and then sell it as a commodity through existing natural gas transmission lines. However, the owner had difficulty cleaning the biogas economically so it met utility grade specifications. Given the current low price for natural gas, this led to the project’s ultimate failure. Maas agreed that given current natural gas prices, using the biogas as fuel in power generation makes more business sense for most dairies.

“Although the State of California wants more of those projects, and were working very hard to try to build those projects, that’s a hard lift,” says Maas.

“That’s a complicated business model, so most people do electricity,” Maas adds.

One further incentive for Open Sky Ranch Dairy to voluntarily pursue the project prior to any regulations requiring methane reduction from the dairy is that the dairy is eligible to sell greenhouse gas offset credits, also known as carbon credits, to help pay for the project. As part of its service, MEW conducts all the paperwork for the verification of the carbon credits generated by the facility.

Upon inspection, Maas says the digester portion of the mothballed installation was in, “pretty good shape. It was built to all the latest water board requirements here in California. It just needed some repairs and redesign.”

This was a huge advantage for TeVelde because construction of the anaerobic digester is by far the most expensive part of any biogas recovery system. The major expense of the project was to remove the old biogas recovery, treatment and transmission hardware down to the concrete foundation, and then install all the new hardware needed to clean the biogas, power the generator, and monitor the overall system.

The project required the installation of blowers to circulate the biogas in the digester, an iron sponge scrubber to remove sulfur from the biogas, a building to house equipment, electrical switch gear to connect the generator to the power grid, and the 800 kW Dresser Rand Guasor engine and generator.

The digester is a continuous flow model with a retention of about 40 days. The raw liquid manure is processed through the solids separator, then through the digester, with the liquid byproduct continuing on to the storage lagoons. It is land applied as fertilizer in the spring and summer.

“The manure system hasn’t changed much,” says Maas. “The main thing is that we are getting energy out of the manure now and stabilizing it somewhat. All the existing (manure management) structures have remained in place. We have just added one more step in the process . . . Also, we take out the carbon and the hydrogen for fuel, but we leave in the nitrogen, phosphorus and potassium, all the things that the soil wants.”

It’s 102 Fahrenheit at Bateman’s Mosida Farms in Elberta, Utah, 60 miles outside Salt Lake City. The heat is taking its toll on the dairy cows. Fans and soaker hoses run. But the heat is also taking a toll on the farmers and the community as the conflict over water usage grows.

The Batemans don’t take the water issue lightly. They continue to improve their processes, work hard to create a sustainable farm, and continually educate people about what it takes today to be a food source. Their hard work is one of the reasons they received an Outstanding Dairy Farm Sustainability award from the Innovation Center for the U.S. Dairy.

Judges evaluated the nominees’ sustainability practices based on their economic, environmental, and community impact. The independent judging panel – including experts working with and throughout the dairy community – also looked for learning, innovation, improvement, scalability, and repeatability.

The Bateman family has grown their farm into one of the largest dairies in the state with 7,000 milking cows. Along with their father, Wayne Bateman, the four Bateman brothers – Jason, Steve, Brad and Lance – currently own and operate the farm.

In addition to the dairy, the brothers also farm 3,000 acres and raise all their own heifers.

Jason Bateman says his grandfather started the dairy a number of years ago in West Jordon. After his grandfather retired in 1972, his dad, Wayne, moved the dairy to its current location. That year they were milking around 250 to 300 cows and have steadily grown.

Today, the fourth generation is coming on board, but only if the farm remains both profitable and sustainable.  

Mosida Farms is a freestall dairy and uses sand for bedding. Jason says the farm is moving from a scrape to a flush system. The flush system will allow them to both better recycle both water and create cleaner sand.

Since around 2008, Batemans have been using a gravity sand sidewalk system. They created it themselves after seeing one in California that they liked because of the low maintenance.

“It has four-foot sides and is 540 feet long,” explains Jason. “The manure comes in at one end about two-thirds up, hits a wall, angles and heads down on a slope. There are two cells so that we can get the sand to fall. We take [the sand] out of our sand cells up to the drying yards, which are sloped with southern exposure.

“We put the sand in windrows,” he adds. “And then we bake it and turn it, and bake it and turn it. It dries the sand, and kills the bacteria. Once the moisture is gone, we move it back into the stalls.”

Drying time depends on the weather. When it 100-plus Fahrenheit, like it has been this summer, it can take just four or five weeks. But other times of the year, it can take up to three or four months.

The farm is able to reclaim 11 to 12 dump truck loads of sand from the sidewalk every day.

“We’re saving about 83 to 85 percent of our sand,” says Jason. “Of course, we’re always adding to that, but we’re able to save a lot in transportation costs, because all of our sand sources are 50 miles away.”

Another area of constant improvement at the farm is the separation system. Mosida Farms is currently downsizing the number of separators to four Houle primary separators, and will be adding Houle secondary separators as well.

Once the manure is separated from the sand, it continues to a 60,000-gallon mixing tank, which allows them to get “a good mix” says Jason.

“Next it goes over to our primary separators.”

The water is collected and some is used for the cows. What water isn’t used continues to build and eventually moves to a storage tank where it pumped onto the fields. What can’t be used on the fields or for the cows, goes on to a lagoon.

“It’s been kind of an evolving thing here since we built the big barn in 2001 perfecting it,” he says. “We’re able to recycle the water many times, that’s part of the reason why we wanted to use this system.”

The solids coming off the separators are composted in windrows and then later spread on fields.

Jason estimates it takes three to six months to fully compost the solids, but it can vary.

“At times we have to add water, because it’s so dry. And it depends on whether it comes out of our heifer pens or if it comes out of the separators. And it also depends on the weather.”

When it comes to spreading, the Batemans use a GPS system and only apply as needed according to their CNMP (Comprehensive Nutrient Management Plan). The compost saves on commercial fertilizer says Jason.

“And it’s better because it’s organic and it’s natural. The nutrients are available. In combination with commercial fertilizer, it works really well.”

The liquids used for irrigation are held in a nearby lagoon. Jason says that in the dry state of Utah, storage is handled a bit differently.

“We don’t have to have 160 to 180 days of storage. We can haul all year if we need to, depending on the weather. If it’s stormy, then we can put it in the lagoon, and if it’s not, then we can haul and do whatever.”

Jason says it’s important to “use every resource very wisely.

“You can save millions and millions of gallons that you’re already producing for the cows that you can use later on the crops.”

The Batemans have also installed a state-of-the-art calf barn that has increased production in the herd and just finishing constructing a 600kw solar farm, which began producing power in late July. The solar farm should be able to provide 90 percent of the farm’s energy needs in the winter, and somewhat lesser in the summer.

“We did it to try to hedge your power bill for the next 20-plus years,” explains Jason.

Even with all the work that the Batemans have put into their farm to conserve water – recycling the same water many times and using only 250,000 gallons a day, which is a relatively small amount for a farm of this size – many people unfamiliar with what goes into farming are upset. They would like to see water taken from the farmers for their own use.

“In Utah, water is a big issue because we’re in a drought. The lakes are drying up. It’s hot. People need to understand that we aren’t farming just to make money. We have to make money to be in business, but we’re providing a food source for them and someday they’re going be choosing between a golf course and their food supply. That’s what we’re trying to educate them towards.”

The Batemans are trying to fight this mindset through education.

“We have a lot of visitors,” says Jason.

Some ask to tour, and others are invited. The farm recently hosted two busloads of young diary science students here from all over the country. They’ve also supplied tours for dieticians that graduated from Brigham Young University.

“We teach them that this is where their food comes from. And if not us, where are they going to get their food from? Are they going to buy it from other countries? Countries that don’t have good safety practices like we do?

“Most people don’t understand everything it takes to bring a gallon of milk to their house. And the tens of millions of dollars it takes to be a dairyman nowadays. I think if you can show them that we have nothing to hide; we treat our animals well; we provide a safe, healthy product for them; there’s value in that.”

Some day Jason foresees the farm will run digesters.

“I’ve seen lots of them and we’ve been all over the country looking at them. I’m still not ready to put one in because they still have a lot of problems. Hopefully our end goal is to generate power off of the digesters, off of the manure, and all those things, and still have the nutrients to grow the crops.”

In the meantime, the Batemans will continue to make their farm more efficient and sustainable.

“We’re not done, but we’re getting closer to the end result of what we want.”

Prestage AgEnergy of North Carolina didn’t set out originally to build the largest co-gen plant to run solely on turkey litter. As vice president Michael Pope says, sometimes these things just “kind of evolve.”

Prestage began seriously considering a poultry litter project as far back as 2011. The company put in time doing its homework – and looking at various systems and why certain systems do and don’t work when dealing with poultry.

“Poultry litter doesn’t have the same BTU value as wood. It’s slightly less,” explains Pope. “But because litter is wood-based, it’s a much more traditional fuel source to work with.”

There was also a mandate to utility companies in North Carolina to purchase a certain amount of renewable energy from swine, poultry, wind and solar.

“We started looking at ways to address the mandate to utilities, and also address any potential issues that may come down the road with poultry litter and land application,” says Pope. “Where we’re located – Sampson and Duplin County – there’s a lot of litter that has to be land applied.

In addition, Prestage had successfully used wood chip boilers in the past, and in particular Hurst boilers.

“We’d had great success with their [Hurst] equipment and their products, and that’s part of what led to us collaborating with them on how we could make this work with poultry litter.”

Hurst Boiler, out of Coolidge, Georgia, was also a good choice because of its long history in the energy business. The international manufacturer of a complete line of gas, oil, coal and hybrid biomass fuel-fired steam and hot water boilers has been operating since 1967.

When Prestage initially went to Hurst with its idea, Hurst wasn’t sure if their boilers would handle 100 percent poultry litter, but an unexpected event occurred in Guatemala that would change the course of events.

During a biomass shortage, a Guatemalan poultry company began fueling their Hurst wood chip boiler with chicken litter. As expected, the boiler ran into some issues, but it continued to operate.

“It was a very manual, and very crude process, but it demonstrated that even without treating the litter like we should, these boiler systems could handle poultry litter,” says Pope.

Creating the innovative boiler system for Prestage became a team effort. Hurst made some slight modifications to its system and Prestage made modifications to how it would handle its litter prior to it reaching the boiler. The result was a 1500 HP biomass boiler, the largest in the United States, fueled 100 percent on poultry litter.

To run the boiler 24/7 will require approximately 175 tons of turkey litter per day.  Prestage doesn’t see that as a problem. Pope says that not only is the company located in a good area for procuring litter, the industry is expanding in the region.

Crews will go out, as normally scheduled, to approximately 60 turkey farms to do a complete clean out of litter or a “cake” cleaning under the feed and water lines. The litter will be transported back to the facility.  And, Pope notes, that although the boiler can run on chicken or turkey litter, the company is currently just focused on turkey litter.

At the Prestage facility, the litter will be brought to a litter building. There the litter will be blended for consistency – nutrient type and moisture content – and then conveyed to the boiler.

“Moisture content is key for utilizing litter in the boiler, and making sure that it gets a fairly consistent product coming in,” says Pope. “Our focus is power production and providing steam for our feed mill to get them off of natural gas. But we’re also focused on using the ash as a fertilizer, as it’s high in phosphorous and potassium.”

Storage is a big piece of the project – both for litter and ash.

While the litter is stored in a large covered facility, the ash will be stored in an enclosed facility because once wet it tends to harden like concrete. The storage space for the ash is large because Prestage anticipates seasonal use by famers.

Prestage doesn’t see itself going into the “Prestage labeled fertilizer bag” business.

“We are teaming up with a very successful regional fertilizer company. We will be using their existing sales channels, and they’re very excited and absolutely believe they can move every ton of ash that we produce.”

The facility will be up and running in December 2016 and Prestage is estimating they will annually produce the equivalent of 95 GWh of power and 9,000 tons of quality ash.

Pope says the nutrient-rich ash product not only gives the company options, but farmers as well.

“The ash can go to fertilizer manufacturers. It can also go straight into field application for the farmers,” says Pope. “That’s nice because a lot of farmers have used poultry litter in land application for their crops, but don’t always get consistent spread and can’t precision farm. So, instead of using litter, they sell us the litter and with the money we put in their pockets, they can take that and buy traditional fertilizer that allows them to precision farm, get better yields on their crops and give the fields exactly what they need.”

The challenges have been exactly what one would expect with a first-of-its-kind system – figuring out exactly what the boiler is capable of, and the make up of the litter to ensure it functions properly and efficiently.

“We’ve learned it’s expensive being innovative. But it’s good, because what it really does at the end of the day is benefit all the poultry growers,” says Pope.

“Growers have to get rid of the litter and land application has been an issue depending on time of the year and the weather. Currently, growers may or may not be able to get the litter out of their houses and land applied. There are certain areas that may be rich in phosphate, where you don’t want to put litter on the ground. Also, farmers never know what the EPA is going to do, and what sort of challenges they may have to face environmentally. What this system does is provide another outlet – a year-round outlet – for poultry growers to send their litter for processing.”

One challenge Prestage didn’t face was finding an experienced crew to run the new facility. An older power plant in the area wasn’t able to successfully complete a conversion from wood chips to poultry litter, and had to shut down. The timing was such that Prestage was able to step in and hire a significant number of people from that facility to operate theirs.

“We’ve got operators experienced in running a power plant and using a wood based product. And they do have some experience from testing poultry litter at their facility. We couldn’t be more blessed,” says Pope. “It was unfortunate that a facility had to close, but we were able to pick up the best of the best to operate this facility.”

Prestage is proud that it hasn’t rushed into this new area, and that it has put in the time and energy to ensure the road it’s taking and the technology sued will be successful.

“Because [Prestage] was new to this arena and because it was all poultry litter, we didn’t want to get out there, fall flat, and it be a failure and a disappointment to the industry,” says Pope. “We want to make sure it works and that it was long-term and that it would create avenues for others or ourselves to expand on what we’re doing.

“We’ve taken our bumps and we got our lumps and bruises, and we know that going forward, we can do this more cost-effectively. I definitely think that this can be replicated at better cost and can provide more benefit to growers and producers in the industry as a whole.”

Does that mean Prestage may build more of these facilities?

“There’s definitely the possibility of putting in additional plants,” says Pope. “We always evaluate what comes along and what makes sense, and we try to stay true to who we are as a company and focus on what we do well. We’re a very successful national pork and poultry company. We’re very good at live production and very good at poultry processing, so getting into power generation and fertilizer production is a new realm, but we’ve got 30-plus years of success behind us and we wouldn’t step out and do these types of things if we weren’t positive we’d be successful
with this.”

Bison Compost LLC produced 1.5 million pounds of compost last year from feedlot manure collected from the North Prairie Bison Ranch in North Dakota. Photo by Contributed photo 

The American bison is making a comeback and a North Dakota-based, start-up company called Bison Compost LLC is hoping this translates into growing sales for their teabag and bulk compost products. Their manure supplier and business partner, North Prairie Bison Ranch (NPBR), hopes it leads to reduced manure disposal costs.

After almost being hunted to extinction, the American bison, or buffalo, has become big business for some Great Plains ranches, and was recently named the National Mammal of the United States.

NPBR manages a 3000-head custom feedlot near Leeds, ND, where they raise the animals exclusively for a single customer. The feedlot is owned by Dennis Sexhus, his son, Sanford, and Keith Kakela.

Bison Compost LLC was formed in 2013 and has three partners: NPBR, Tom and Judy Duenow, and Shelley Mathison-Holmes. Although the Duenows live in Elk River, Minn., and Mathison-Holmes in Winston-Salem, NC, all have roots and past associations with the Leeds area, which is how they found each other to formalize the partnership. The company markets its products under the names ‘Buffalo Earth’ and ‘No. 2 Brew Compost Tea’ for plants.

While he has yet to sit down and crunch the numbers to calculate if composting is delivering a net financial benefit to the bison ranch, Sexhus says they have reduced their number of Frontier hydraulic-push manure spreaders from three to one because the composting process reduces their manure volume by about two-thirds.

Sexhus says NPBR’s main motivations for taking the composting route were to reduce volume, derive a potential extra income from compost sales, and to help out the environment by switching to compost from land applying raw manure. At present, he says all their raw manure is being composted, but only a portion is being sold. The rest is land applied as organic fertilizer for their cash crops until such time as the compost business builds up its distributor network to take all the compost.

“Manure management is a cost for us and is a fairly expensive part of the feedlot business to properly dispose of the manure,” says Sexhus. “We were motivated by trying to turn what was really a liability for us into an asset.”

However, he has a realistic view of the costs associated with converting raw manure into compost.

“I believe that we are benefiting, but making compost isn’t free,” Sexhus says. “This business is fairly new and our goal is to grow it into a viable business. I do know that there are savings, but there are also costs associated with it.”

Prior to the composting venture, the ranch typically stockpiled and land applied its raw manure. It is a combination of animal waste with grass, hay, straw or corn stover.

In addition to substantially reducing raw manure volume, compost also has a lot less odor, and is largely free of weed seeds, pathogens, and fly eggs. These are some of the main selling points of compost, not to mention its benefits as an organic plant food where it increases fertility, water-holding capacity, bulk density and biological properties.

Describing the manufacture of the bison compost as a “warm weather” endeavor, Sexhus says the accumulated manure from the pens is stockpiled and then put into windrows on a designated, 10-acre, drainage-controlled, composting site provided by the bison ranch next to the feedlot.

Tom Duenow says his career as a food business manager brought him considerable experience in recycling, so the idea of recycling manure into compost had some appeal to him. Also, his wife, Judy, had a strong connection to the North Prairie area of North Dakota, having grown up within a couple of miles of the NPBR feedlot. Her family had close family connections with the bison ranch’s owners. Judy also had experience as a business partner with Dennis Sexhus, raising bison in the 1990s before selling out when prices went south.

“I started a conversation with Dennis about the possibility of composting and we just rolled it back and forth for a year or two,” says Duenow. “In 2013, we decided to create a partnership and start composting the bison manure.”

Mathison-Holmes spends a lot of time in North Dakota and is a strong advocate for women becoming more involved in business. Her family comes from Fargo. She was interested in becoming involved in a recycling business that created value-added end products like compost. In fact, she started a venture in manufacturing and marketing bison compost but lost her source of manure. So she reached out to the Duenows and became part of the Bison Compost partnership.

The owners did not have a lot of experience manufacturing premium quality compost, so they turned to the U.S. Composting Council and the North Dakota State University (NDSU) Extension service for technical assistance. They credit individuals like NDSU livestock environmental specialist Mary Berg with providing great and ongoing assistance in helping to launch their business venture.

Using an excavator, dozer, and front-end loader from the ranch, the feedlot manure is piled into 200-foot-long windrows on the composting site that are 12-feet wide and 8-feet tall. The site has enough room for 15 windrows as well as room for expansion. Temperature is the critical benchmark measured when manufacturing compost and it is measured frequently. The piles are allowed to heat up to 160 Fahrenheit three times. Each time it reaches that temperature, a Vermeer CT612 compost turner – owned by Bison Compost – turns the piles. After turning, the piles cool down then heat up again. The heat is generated by the microbes within the windrows doing their job of converting the manure into compost.

“I like to say that it is kind of a natural pasteurization process,” says Duenow, adding this is how and when the toxins, fly eggs and weed seeds are destroyed.

After turning three times and the heat stabilizes at a lower temperature, the compost piles cure for four weeks. The entire process takes between two and three months.

The black compost is screened to 3/8-inch consistency through a screener supplied by PowerScreen – located in Rogers, Minn. – before being sold in bulk or loaded in small quantities into teabags. Because of the seasonality of compost production, the company rents the screener once it has a large amount of compost accumulated. Timing the production of compost to stockpile for the entire year is an important part of the planning and marketing process as no compost is produced during the winter yet there may be demand for compost from plant enthusiasts.

What Mathison-Holmes brought to the business was the concept of a unique ‘teabag’ compost gardening product. This is a small amount of compost packaged in a teabag. It is dipped in water for about 24 hours and during this steeping process, the compost nutrients are released and ready to use as organic plant fertilizer.

While Bison Compost LLC is still in its infancy, Duenow says the owners have already learned some important marketing lessons. Perhaps the most important is the decision to sell their bagger and focus on selling large quantities of the bulk product to other companies who then bag it under the Buffalo Earth name. Part of the challenge they face is being situated in North Dakota, which is quite some distance to market with a limited labor pool. That’s why for now, the company has focused on marketing its compost in bulk both locally and over longer distances as well as marketing it in smaller, more manageable quantities as the No. 2 Compost Tea product.

In addition to giving the environment a hand-up by converting the raw manure to compost, Bison Compost is also providing much needed employment for a local organization that works with handicapped individuals. They have the contract to package the No. 2 Compost Tea product.

The Duenows and Mathison-Holmes continue to work hard on the marketing front to attract interest outside their local area, and so far, their marketing strategy has worked out quite well. They have sold a large volume of compost to a landscape products company in Minot, ND, which is blending it to create potting mix and garden mix for its customers. Bison Compost also has nursery and garden distributors established in Minnesota, North Dakota, South Dakota and Northern Iowa, as well as a distributorship established for six states around New York.

Last year, the company produced about 1.5 million pounds of compost. Duenow says they generated about $30,000 in sales and they hope to double that amount this year as well as make good progress on establishing a national market particularly for the teabag product. Their target audience is nursery owners, gardeners, individuals involved in soil remediation and reclamation, as well as gardening enthusiasts.

While there is no difference in the process of manufacturing compost from bison manure or cattle manure, Duenow says they are hoping to leverage their sales to some extent on the growing profile of the American bison itself. They are also hitching their wagon to the green movement, promoting their product as a natural alternative to commercial fertilizer, from a source where the animals are raised without hormones or antibiotics.

To support the start-up, Bison Compost received a $135,000 grant from the North Dakota Agricultural Products Utilization Commission, and Duenow says a considerable amount is being used in their ongoing marketing efforts.

“Our name and our product are really gaining more and more interest,” he adds. “It is so much fun to go to shows like Pride of North Dakota and have people come back again and buy our product.”

It is the quintessential dilemma faced by farms that generate significant amounts of liquid manure – should the farmland apply the manure themselves or should they hire a custom manure applicator?

Both have their pros and cons, and it often comes down to how much the farm owner trusts his custom manure applicator with the service they provide. Some issues are really not in the custom manure applicator’s hands, like the weather and exactly when the application is done, because during prime time in spring and fall, the phone never stops ringing. Farmers often must wait their turn for the best custom applicators, which may not always work well with the farm’s cropping timetable. Advantage – farm-based system.

On the other hand, there is the time issue. Some farmers believe it simply makes more sense to hire a custom manure applicator because they and their employees need to stay focused on their dairy or hog operation. And then there is the cost of investing in tankers or a drag hose system, plus the learning curve required to use them properly. Advantage – custom manure applicator.

Dairy farm hand and engineer Mark Tucker believes there is a market niche and a demand for a simple-to-use and affordable drag hose system suited for farmers, and he believes the SlurryQuip system fits the bill.

“In my mind, it fills a gap in the market,” says Tucker. “Most of the North American systems are built overly big for your average farmer. This system is built for the farmer to use.”

The Northern Ireland-based manure application equipment manufacturer is setting up shop in North America. Its systems are currently widely used in the United Kingdom, Australia and New Zealand. The first North American system was sold last fall to Happy Rock Holsteins in Gladstone, Man., where Tucker is employed as an engineer and farm hand.

The dairy is owned by Steven Smith and has about 750 head, with 350 to 400 milking cows housed in a new free stall barn built two years ago. It has a slatted floor with liquid manure storage beneath it. The manure is pumped out twice a year and land applied. The dry cows and replacement stock are housed in an older barn with straw bedding that is cleaned out every couple of months, stockpiled, and then land applied using two, Kuhn manure spreaders. The dairy also manages about 3000 acres of cash and feed crops, in the vicinity of the dairy. This is where both the liquid and solid manure is land applied in spring and fall. Manure can only be spread in Manitoba between April 10 and November 10.

For two years after the new barn was built, Happy Rock Holsteins hired a custom manure applicator to pump out and land apply their liquid manure but it didn’t turn out as well as they had hoped. In fact, Tucker says land application of the liquid manure by the custom manure applicator destroyed an alfalfa crop twice, which encouraged the dairy owner to want to investigate a drag hose system that the farm could operate themselves. Farm hand Tucker was given the task to investigate drag hose systems and to make recommendations. That’s when he encountered the SlurryQuip system. Given his engineering background, he was quite capable of dissecting the pros and cons of each system and, although SlurryQuip had no systems working in North America, Tucker came to the conclusion that it was the right system for Happy Rock Holsteins to purchase and operate on their own.

While it requires dedicated farm employees to operate the SlurryQuip system, Tucker says that it has its advantages. First, farmers can apply the manure on their own timetable and second, they have the opportunity to more carefully manage nutrients being applied on each parcel. He says, for example, that there are plans at Happy Rock Holsteins to make several applications each year on some parcels after each alfalfa cut. Organizing this type of timely and frequent service hiring a custom manure applicator would be a costly endeavor.

What he also likes about the SlurryQuip system is that the farmer can practice more precise farming, based upon the global position system (GPS) in the tractor, and the ability with the SlurryQuip system to carefully control the flow. With these two features, the farmer can place the liquid nutrients exactly where and in the volume that it is needed based on soil sampling. This is generally contrary to what Tucker sees as the major trend in North American custom manure application, which seems very focused on applying a fixed volume per minute across an entire field versus making application adjustments on-the-fly depending on where it is needed.

“What attracted me to this system is its accuracy,” says Tucker. “Applying volume per minute is fine for the applicator who is being paid by the gallon. For a farmer, who wants to put on the manure accurately, in my view, this system is ahead quite a bit in that respect.”

Another feature that Tucker likes about the system is the ability to reduce flow from the dribble bar by up to 75 percent, meaning that the tractor operator can significantly reduce flow particularly when making turns and also in the event of the need to reduce flow in a hurry because of a flow issue. He says that is likely what caused the problem in the damaged alfalfa field owned by Happy Rock Holsteins – a problem with over application by this particular custom manure applicator, as the operator made slower turns without reducing the flow rate.

Happy Rock Holsteins essentially purchased the SlurryQuip system based on Tucker’s research over the Internet. The complete system arrived on the farm in a container, almost completely assembled. It was his job to complete the assembly, attach it to the tractor, and put it to work. Given his background in agricultural engineering, he says it was less scary for the dairy to make the equipment purchase in this way. There were no issues attaching the system to the farm tractor’s PTO and three-point hitch.

“When we looked at the system, certainly in my eyes, it was fairly simple to see how it worked, the fact that it could work, and that there were no design flaws,” says Tucker. “Both Steven and I saw many design advantages. We saw that it was much simpler to use from the farmer’s point of view than what we saw in North American systems.”

He and the dairy owner also liked that all the components are galvanized.

“In 10 years time, assuming we don’t bend or break anything, the machine will still look like new,” says Tucker.

He says the design of both the SlurryQuip hose reels and lift systems, and how they are designed to work with just one tractor in the field, powered off the tractor’s PTO and with the reeler mounted on the dribble bar, this makes it possible for one person to manage the whole field operation, which they accomplished at Happy Rock Holsteins. They only had one other person involved, looking after the pump at the farm site.

The SlurryQuip system was put to work throughout last fall’s application season with no issues. Shortly after the manure was land applied, it was disked into the soil.

“We made some errors ourselves, given the learning curve,” says Tucker. “But as far as the machine, we didn’t have one problem. The system worked straight out of the crate.”

Their SlurryQuip system consisted of two Bauer pumps, a Vogelsang macerator, a Krohne flow meter for inside the tractor cab, 2.4 kilometers of a combination of 5-inch and 6-inch Oroflex umbilical hoses, four SlurryQuip reels, two SlurryQuip reel lifters and a 31-foot wide SlurryQuip dribble application bar. The dribble bar was mounted on a 724 Fendt tractor, which Tucker says provided far more power than they needed. He suspects that a 100 horsepower tractor would have been adequate for their system because it is a dribble bar versus an injection system. They used the PTO from another farm tractor to power the pump to suck the liquid manure from the tank through the umbilical hoses to the applicator in the field. The system allowed the dairy to reach about 70 percent of its farmland, using only one pump.

Many of the system’s components, like the pumps and hoses, are common, off-the-shelf brand items available worldwide, although Tucker says there are few wear parts on the equipment.

June 7, 2016, Dundee, OH — Welcome to the manure fortress, said Tim Sigrist, stretching his arms to show off three acres of composting manure. What started as trial and error and homemade contraptions, continues to be trial and error and homemade contraptions, but has become a successful business venture for the Sigrist family.

Bull Country Compost, in Tuscarawas County, sold 44,000 bags of compost in 2015, which is a significant jump from the 10,000 to 12,000 bags they sold their first year back in the early 1990s. READ MORE

 Hog manure from the project will produce approximately 2.2 billion cubic feet of pipeline quality renewable natural gas (RNG) annually, or the equivalent of 17 million gallons of diesel fuel annually (17 million DGE). Photo by Contributed photo

What happens when you bring an alternative energy company and pig farms together? Well if the farm owner is Smithfield Foods Hog Production in northern Missouri, which finishes two million pigs a year, and the energy company is Roeslein Alternative Energy (RAE), the answer is a lot of renewable natural gas.

About six years ago, Smithfield (then Premium Standard Farms) was dealing with issues around its sustainable manure management plan. Rudi Roeslein, founder and president of Roeslein Alternative Energy, didn’t see a problem but a potential partnership. His company would capture the methane from Smithfield’s 88 lagoons spread out over nine farms and convert it into natural gas.  

“We have a project that makes both economic sense and environmental sense. And we have worked through the technology of how to make it happen,” Roeslein says.

Project is launched
Discussions between the parties resulted in just such a project launching two years ago, with the goal to have the first natural gas-produced pig manure to be injected into an ANR pipeline sometime in the summer of 2016.

The project, although large in scale, is fairly simple in its overall concept. When it’s complete, Smithfield’s farms will have impermeable covers installed on each lagoon. When temperatures are favorable, anaerobic digestion will begin and biogas will be created. The biogas will be filtered/purified (collected and cleaned of sulfur and other impurities) into a gas that is 98 percent methane and has the same molecular composition as natural gas. The cleaned biogas, or renewable natural gas, will be transported underground to an interconnection with the ANR pipeline, and then transported to customers across the country.

When in operation, the hog manure from the project will produce approximately 2.2 billion cubic feet of pipeline quality renewable natural gas (RNG) annually, or the equivalent of 17 million gallons of diesel fuel annually (17 million DGE).

“We cannot look at manure as waste any more,” Roeslein says. “We have to figure out what we can do with manure to keep it in the cycle. There are no silver bullets. But this is a small step in showing how to use these underutilized resources to produce energy and return everything that remains productively back to the landscape. Because that’s how nature really works.”

Large demonstration
One of the reasons this project was an ideal demonstration of how the biogas technology can work with the pig industry was location. The ANR pipeline runs across the Smithfield farms.

“RAE has been making very good progress covering the lagoons in a systematic approach,” says Sheldon Ripson, spokesman for Roeslein. “There are 88 lagoons, each approximately four acres [holding 15 million gallons of manure] that need to be covered, with a number of other pieces of equipment to handle the gas being installed along the way. It’s fairly complicated. But they are making steady progress.”

RAE is investing about $120 million into the biogas project. The company anticipates the project won’t just provide renewable natural gas, but also provide hundreds of jobs, and a model for how the swine industry can achieve a more sustainable and profitable business.

Ripson says future partnerships between RAE and other farms will take various shapes.

“Part of the vision here is to show this as a demonstration project on how a system like this can work for handling manure. It’s applicable on any number of operations across the Midwest.”

A recent U.S. Department of Agriculture report said there are thousands of hog operations where anaerobic digestion of hog manure can be economically viable.

“Farmers are busy doing what they do,” Ripson adds. “RAE brings expertise in delivering projects. A company like RAE can fill the gap with a model that makes sense for the producer, both economically and environmentally. Because if you don’t have both of those, it really doesn’t make a whole lot of sense to go forward.”

Simple concept, big benefits
It will take months from the covering of the first lagoon to the last. Methane production, however, doesn’t wait. As the pipelines and purification systems are being installed, the methane is being collected from the first lagoons and being flared off.

Although natural gas isn’t being created yet, Smithfield has already seen some positive effects from just installing the covers. And, the two companies anticipate:

  • the prevention of approximately 400 million gallons of rainfall water from entering lagoons
  • the elimination of water treatment costs, as rainwater will safely return to the groundwater supply
  • the prevention of approximately 850,000 tons of CO2 equivalent methane reaching the atmosphere
  • the elimination of hog manure odors

“One of the biggest initial reasons for getting into the project was heavy rainfall that presented an issue with the lagoons,” Ripson explains. “There is a marked improvement with lagoon covers, which keep rainwater out. The rainwater is clean and goes back into the groundwater supply.”

Or the millions of gallons of clean water can be captured to feed hogs or irrigate fields.

Another benefit of anaerobic digestion is the variety of byproducts that can be created from the digestate solids. It can be spread on crops, or it can be used for agriculture, landscaping and public works projects with the benefits of erosion control, water absorption, soil nutrient infusion, and reduction of petroleum-based fertilizer use.  

Selling the compost to third parties is something that will be looked into down the road. Currently, Smithfield, which has large tracts of land (approximately 50,000 acres), is pumping the liquid off the lagoons and spraying onto their fields.

Introducing prairie grass
The second phase of this project – and one that RAE is extremely excited about – is the potential of adding prairie grass to the mix. There is plenty of land in the Midwest that is considered either highly erodible or marginal, and where prairie grass is suited to grow. Farms with land that falls into that category could ideally see that land becoming profitable versus a liability, and provide habitat for wildlife.

“We are looking at native prairie restoration opportunities to produce additional feedstock to increase energy output. It improves the economic model of the project,” says Chris Roach, director of Roeslein Alternative Energy. “But that land restoration is also how we create more habitat and ecological benefits, which are frankly missing from all other models of producing renewable energy.”

Also, prairie grass is by itself a great fuel source. Restored grassland plantings from multiple species can produce fuels with greater net energy gains per acre than corn or soybeans. And mixtures of native perennial grasses and other flowering plants provide 51 percent more usable energy per acre than corn ethanol.

“It’s not something new,” Ripson says. “Germany has been doing it for some time. They have about 7,000 anaerobic digestion systems that handle waste grasses and other kinds of biomass to generate methane. There’s no reason that can’t happen over here as well by using prairie grass feedstock.”

Big opportunities
The enormous scope of this project requires both flexibility and patience. Each of the nine locations requires a different set up. Due to that, it’s hard to estimate the final cost. But RAE owner Rudi Roeslein is dedicated to making it happen.

He’s not the only one who sees a big opportunity. There are currently 239 anaerobic digestion facilities in agricultural operations in the United States. And AgSTAR estimates that biogas recovery systems are technically feasible at more than 8,000 large dairy and hog operations.

“The RNG can go right into the pipeline and can be used anywhere across the country once it’s in that pipeline,” Ripson explains. “The company’s first offtake client for this project is Duke Energy in North Carolina. There is already a contract in place and the company intends to take a lot of this gas to help meet its renewable energy requirements.”

There also doesn’t look to be any problem finding future offtake customers, Ripson says.

“There’s an emerging market for renewable natural gas. For example, that market is more established in California where there’s quite a large interest in this kind of thing. The economics are quite favorable for renewable natural gas.

“The technology we have developed is ready to be deployed commercially in a project that makes both economic sense and environmental sense,” Roeslein says. “This is not just about converting the manure from almost two million pigs into renewable energy. It’s about taking environmental sustainability to a new level.”

An overall solution
This summer will be a big milestone for RAE as the RNG created from the two million pigs hits the pipeline. But many see this as only one of its many positive benefits.

“This project will show how farmers can do more than produce food. We can make energy, we can reduce waste, and we can be good stewards for our most important resources – land and water,” says Blake Boxley, director of environmental health and safety for Smithfield Foods Hog Production.

It’s a solution that is a win/win for everyone, Ripson says – the farmer, the energy companies, the offtake customers and the environment.

Jesse Jones, owner of Jones Custom Manure Hauling in Pennsylvania, has done an exceptional job of “keeping the wheels turning” on his custom manure application and hay-making business.

The key to his success has been to diversify his business and his list of clients, keeping an open mind to any opportunities that might come his way. Conducting most of his business in Pennsylvania and neighboring Maryland, Jones will travel as far as three and a half hours from home to work.

“If it pays, we’re willing to go,” Jones says. “We try to utilize our equipment all year long,” and if last year is any indication, they have met that goal, as they were busy throughout the entire year.

The lynchpin of his business – located in Carlisle, about 35 miles from Harrisburg – are his tractors, which not only pull his manure tanks through the fields but also transport the tanks from job to job, and work in snow removal at various warehouses and parking lots, using the snow pusher attachments placed on them. In addition to custom manure application, Jones has also diversified into custom hay merging and mowing to help local dairy farmers produce silage. The tractors are also used to pull the company’s mowing and merging equipment.

Jones’s primary business is providing custom manure hauling and application services for the large Pennsylvania dairy industry, in an area he describes as very similar in appearance to the Irish landscape. Unlike the western United States, he says it’s rare to find a 200-acre single patch of farmland in that part of the country. Like rural Ireland, the area consists of numerous small patches typically less than 100 acres each, with a lot of houses, plenty of hills, and narrow roads. As the area is situated between two mountains, Jones says that he is fortunate in that different areas tend to dry out at different times in spring. So he is not pressed from all quarters to make himself available to land apply manure all at the same time. He has the luxury of being able to move his equipment from one area to another at precisely the time it is needed.

Jones Custom Manure Hauling land applies more than 120 million gallons of manure annually, with most of the manure surface applied on the soil. His dairy clients milk anywhere from 40 to 600 cows. The manure from each dairy farm is land applied on their own farmland. Jones has transported manure from the lagoon for land application up to 10 miles.

However, he has also found a way to diversify beyond the local dairy industry, which is prone to fluctuations in milk prices. About 20 percent of his business is using his manure application equipment to inject organic material shipped in from various food processing facilities. Jones has a contract to receive the material, which is then either stored in liquid manure lagoons among his dairy clients who have agreed to accept the food waste for land application later, or sometimes it is land applied as it arrives. He says this organic material is in high demand among local farmers because of the positive impact it has as fertilizer in crop production.

“We’ve seen crazy results,” Jones says. “We’re talking about some miracle grow here. There is about 70 pounds of nitrogen to a tanker load of it.”

Jones owns the business with his father, Jason. It was incorporated in 2004. Jones grew up on the family dairy farm, following in his father’s and grandfathers’ footsteps. However, he says that working with livestock didn’t appeal to him. He describes himself as someone who prefers to work in the field running equipment, which was his biggest motivation for taking up a career in custom manure application. He started by working for someone else, and when that business owner wanted to sell out, he jumped at the opportunity to strike out on his own and hasn’t looked back since.

His father continues to actively farm, managing a dairy with 100 milk cows and planting crops on 800 acres. Some of the food processing waste that Jones is contracted to land apply is applied on this acreage as organic fertilizer.

Over the years, the business has grown steadily both in the size of its manure applicator fleet and in the geographic area that the company services. Jones says the business has had its ups and downs, particularly during a three-year stretch starting in 2009 when there was a glut in milk production and dairy farms were finding it hard to keep the lights on. The company faces a similar situation now. While their input costs have gone down because of the price of fuel, milk prices have also taken a nosedive. Also, Jones is in an area with a large Mennonite population, and when they decide to do business with someone else, they tend to do so as a large group. Despite the challenges over the years, Jones’s strategy of business expansion and diversification has paid off, as demonstrated by his recent purchase of five new John Deere 7290 auto track and auto steer-equipped tractors to replace four John Deere 7280 tractors purchased in 2012.

The company had been using Series 8 John Deere tractors previously but was feeling squeezed on the cost when they investigated a new fleet of tractors.

“We discovered that the Series 7 John Deere would do just as well as a Series 8 would, so in our eyes, it is a big little tractor and it does what we need it to do, which is why we took that route,” Jones says.

In addition to these new John Deere tractors, Jones also has a Fendt 930 tractor and six 6,300-gallon Houle manure tanks. The company evolved into more manure injection once it took on the food processing disposal contract, outfitting two of its tanks with Houle toolbars equipped with Dietrich 70 series injectors. The remaining four tanks surface-apply the liquid manure. They also have two Houle lagoon agitation pumps and one Dryhill agitation pump.

They added hay mowing and merging to their complement of services in 2012, and this is accomplished using Pottinger triple hay mowers, an H & S hay merger and an Oxbo hay merger.

Jones says he is open to the idea of investing in a drag hose system, but given the number of hills in the area, the smaller parcels of land and the number of housing developments being constructed, it would have to be the right circumstances with a customer before he could justify making that move. Right now, he says his tanker system is a good match for his customer base.

Jones has worked hard and, he says, “too many 24 hour days” during the past 12 years to develop a modern fleet and a professional service, taking any required training to ensure that he and his four employees are qualified according to the standards of various states where he conducts his business.

Over the past decade, he says there have been many legislative changes intended to ensure that farms have a nutrient management plan and that custom manure applicators land apply according to a plan typically developed by an agronomist. He adds there is greater concern about nutrient drainage into watersheds and he has adapted his application practices accordingly to ensure he is leaving an adequate buffer, depending on whether or not the farmer has sown grass in drainage areas to minimize the potential for manure seepage. Winter application rates have also changed, limiting their application rate to 5,000 gallons per acre, but Jones adds that applying in winter takes common sense. If there is a foot of snow on the ground, there shouldn’t be any manure spreading.

“We are manure certified,” says Jones, which required a daylong course offered by the Pennsylvania Department of Agriculture, followed by a test.

“If you didn’t pass that test, you shouldn’t be hauling manure,” he adds. “New laws have come into effect, there are certain setbacks that we have to deal with now, and we also have record keeping of where we put each individual gallon into each individual field.” While he now spends about double the time for record keeping and billing, he believes that new laws tracking where manure is applied have elevated the general level of professionalism among those willing to adapt to new standards.

To this point, they have not installed flow meters in their tractors, but calculate the application rate based on their speed and the acreage that they are covering.

“We know how we are putting it down with simple math,” Jones says. He adds that so much of operating a successful custom manure application business is just using common sense on where and when to apply.

He says over the past decade, the area in which he works has witnessed a lot more urbanization, with many individuals moving in but working in places like Washington. This has added another element to how he conducts his business on a day-to-day basis.

“The farms have always been there, so they [neighbors] know that the manure is going to get spread at some point,” Jones says. “We’ve had minimal complaints. We’ve done this for a long time, they see our rigs, they know what time of year that this is going to happen, so it’s expected. If they move to the country, they have to expect that.”

March 21, 2016, Loyal, WI – Meyer Family Dairy in Clark County, Wis., has included the LWR Manure Treatment System as part of its latest expansion strategy.

This addition will allow the dairy to add more cows without having to acquire more land for manure storage. Also, by concentrating manure nutrients into a stable fertilizer, no additional land will be required for manure spreading. Most significantly, by adding the LWR system they will have the ability to recycle up to 75 percent of the water back from the dairy manure, eliminating of the need to drill a high-capacity well.

Meyer Family Dairy is located in a dryer part of the state and was considering the installation of a high-capacity well before deciding to install the LWR system.

“We’ve had some fairly aggressive growth over the last few years,” says dairy spokesperson Mike Meyer. “In order to achieve our targets, we needed an additional water source to wash our sand bedding. This installation will allow us to achieve our expansion in a sustainable way.”

The regulation of groundwater withdrawals has been a highly debated topic in the state of Wisconsin, as it is in most parts of the U.S. Although farmers use groundwater in reasonable and productive ways, they continue to be faced with regulatory pressure. Wells are regulated depending on capacity, such as 70 gallons per minute, or 100,000 gallons per day. Farmers must acquire a permit for a high-capacity well and that permit must be approved by the WI Department of Natural Resources. In 2011, the Wisconsin Supreme Court issued its Lake Beulah decision, which has led to regulatory uncertainty in the state for any reconstructed wells, replacement wells, existing wells and new wells.

“It has been said that groundwater is the number one issue of the future,” says Ross Thurston, president of LWR. “By installing the LWR system, Meyer Family Dairy will have more control over their water resources. They won’t have to drill an additional well, battle regulations, or ask permission to access more water. They have water already available to them, which can now be unlocked by the LWR system. This is an exciting installation as it demonstrates that the LWR system is not only a manure management tool, but that it is truly a sustainable water source for livestock operations. ”

The system, scheduled for installation this summer, will be the third in Wisconsin.

March 21, 2016, Merrillville, IN – Chicago startup AmpCNG launched at a farm in northwest Indiana that converted cow manure to renewable natural gas.

Nearly five years later, that manure from Fair Oaks Farm is still a core part of the West Loop-based startup’s business. But its reach has grown. It now owns and operates 19 compressed natural gas, or CNG, stations in eight states, fueling the increasing number of vehicles that operate on the resource. READ MORE
