Microwave-based system takes stink out of manure management

July 28, 2017, Vancouver, B.C. – A spin-off company from the University of British Columbia is promising to make a crap job a good deal easier and cleaner, with a scalable waste-processing system.
Manure management practices on local dairy farms routinely raise a stink from their residential neighbours when the slurry is sprayed on fields, as well as from American farmers who complain of cross-border water pollution resulting from excess nutrient runoff.
Boost Environmental Systems, a new firm, is testing a system that uses microwave heat and hydrogen peroxide to drastically reduce the volume and the composition of manure and sewage solids. The resulting waste is easily digestible with existing systems and the liquid is a rich source of a commercially valuable fertilizer called struvite.
Demonstration-sized units are installed at the UBC Dairy Education Centre in Agassiz and the James Wastewater Treatment Plant in Abbotsford, according to Chief Technology Officer Asha Srinivasan, a post-doctoral fellow at UBC. A third pilot installation is being planned with Metro Vancouver. READ MORE
