2013 | WI | Rosendale Dairy | Agriculture
Anaerobic digester system installed in 2013 processing approximately 350 tons of manure per day from 8,500-cow dairy using two CSTR digester tanks. Built as a partnership between the University of Wisconsin-Oshkosh and Rosendale Dairy.
View project source2022 | Vir Clar Farms | Agriculture
1-Stage Pressure Swing Adsorption (PSA) gas upgrading plant installed in 2022 on an existing anaerobic digester at a 2,000-cow dairy farm to generate pipeline-injectable renewable natural gas.
View project sourceEdmonton, Canada | City of Edmonton | Waste Management
Dry fermentation system constructed for the City of Edmonton in partnership with the University of Alberta to convert organic waste into energy. Supported the city's goal of diverting 90% of residential waste from landfills and reducing greenhouse gas emissions. Integrated into Edmonton's existing composting facility to maximize the value of both the digestate and biogas produced from organic material.
View project sourceSeaboard Energy | Food & Beverage
1-Stage Pressure Swing Adsorption (PSA) gas upgrading plant installed for Seaboard Energy to generate renewable natural gas for pipeline injection from pork processing waste biogas. Seaboard Energy had previously fueled boilers with gas generated from anaerobic digestion of pork processing waste and identified gas upgrading and grid injection as the higher-value alternative.
