The Bio-Terre technology for anaerobic digestion of hog manure, developed by Agriculture and Agri-Food Canada, is a patented process that uses anaerobic microorganisms adapted to low temperatures (15°C to 25°C). These microorganisms are kept in sequencing batch reactors (silos next to the livestock building). Successful outcomes were achieved after 3 years of operation at this commercial hog farm.

In a pilot project using technology developed by a research team led by the Alberta Research Council and Highland, under license to Highmark Renewables, the manure from 7500 head of cattle is producing slightly less than one megawatt of electricity - enough power to service the requirements of the feedlot, in addition to a farming community of about 2000 people. The technology being used is known as the Integrated Manure Utilization System (IMUS).

Clear-Green Environmental has partnered with Cudworth Pork Investors Group (CPIG), SaskPower Corporation, Ag-West Biotech Inc., The Canadian Cement Association and Canadian Adaptation and Rural Development Saskatchewan to install a commercial manure processing facility next to the CPIG hog barn. The project involves the design, construction, commissioning, optimization, operation and improvement of the technology as applied to this site.

The project is a commercial demonstration project where advanced anaerobic digestion technology is being coupled with newly developed nutrient separation technology to produce a variety of valuable end products.

The Klaesi digester is using an off-the-shelf Swiss design that processes the manure from a herd of approximately 140 milking cows (300 cattle in all). The digester is built into an existing manure pit, with a rubber membrane on top that expands as biogas is produced. Spent digestate is spread on the farm's 500 acres. The system produces slightly more than 450 kW a day metered into the grid.
