Anaergia Inc. will construct a biogas plant in Kasaoka, Okayama, Japan, for Toyo Group subsidiary Toyo Energy Solution Co. Ltd. (Toyo). The facility will produce renewable electricity using biogas made by anaerobically digesting about 275 tons (250 tonnes) of cow manure per day from Okayama Prefecture farms. The resulting biogas will fuel a combined heat and power generator system. The system will produce about 1.2 MW of renewable electricity, enough to power about 2200 homes each year.
Anaergia will design, engineer, install, and commission the plant. Toyo will serve as the engineering, procurement, and construction contractor. The new facility will use Anaergia’s advanced anaerobic digestion technology and other proprietary resource recovery and treatment equipment.
“Wastes such as manure, sewage biosolids, and food scraps create two-thirds of all point source emissions of methane, a greenhouse gas that is 85 times more potent than carbon dioxide. Stopping these methane emissions from waste must be a central tactic in curbing global warming,” said Andrew Benedek, chair and CEO of Anaergia. “This new bioenergy plant will not only help Japan reduce methane emissions from manure, it will also reduce the need for liquefied natural gas [LNG] to generate electricity. We look forward to building many more plants in Japan with our partner Toyo to help the nation meet its carbon neutrality goals.”
The Kasaoka project is Anaergia’s second with Toyo. In 2019, operation began at the Toyo Biogas Power Generation Plant in Yabu City, Japan. The wet mesophilic anaerobic digestion facility generates power by digesting livestock manure and food residues. The yielded biogas is used as fuel for INNIO Jenbacher gas engines.
