B.C. project seeks to clean up manure

A Vancouver college is looking for new ways to manage manure in British Columbia’s Fraser Valley.
Working with Muddy River Technologies of Delta, B.C., researchers at Langara College are seeking a cost effective way to prevent soil degradation and water contamination by removing phosphorus, nitrogen and other byproducts from animal manure.
The Fraser Valley is home to about 500 dairies, and the high amounts of slurry cause environmental and economic problems. Farmers do not have enough land to dispose of it, and they cannot expand because of the limitations placed on them by excess manure, said Langara researcher Kelly Sveinson.
This spring the college received $90,000 from the B.C. Innovation Council Ignite Award to support the project involving Sveinson, chemist Todd Stuckless and Rob Stephenson, chief technical officer of Muddy River Technologies, which works on water and waste treatments.
The project involves removing phosphates from manure using an electrochemical process similar to that used in environmental cleanups. The second step is to use a biochar carbon filter to capture ammonia that can be released as nitrogen. Ultimately those products could go back on the land as fertilizer. | READ MORE
