Anaergia Inc. plans to construct a biogas plant in Kasaoka, Okayama for Toyo Energy Solution Co., Ltd.. The facility will produce renewable electricity using biogas made by anaerobically digesting cow manure from Okayama Prefecture farms.
The plant will prevent about 13,500 tonnes of CO2e in emissions from the manure and from fossil fuels that would have been used to generate the power, the equivalent of taking about 2,900 cars off the road for a year (calculated based on a 20 year Global Warming Potential).
The project will anaerobically digest about 250 tonnes per day of cow manure from the region and use the resulting biogas to fuel a combined heat and power generator system. The system will produce about 1.2 megawatts of clean renewable electricity, enough to power about 2,200 homes each year. Anaergia will design, engineer, install, and commission the plant. Toyo will serve as the engineering, procurement, and construction contractor.
The Kasaoka project is Anaergia’s second with Toyo; the company also recently built a facility for Toyo in Yabu City, Japan, that converts farm and food waste into renewable energy. The new facility will use Anaergia’s anaerobic digestion technology.
“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, Chairman and chief executive officer of Anaergia. “This new bioenergy plant will not only help Japan reduce methane emissions from manure, it will also reduce the need for LNG to generate electricity. We look forward to building many more plants in Japan with our partner Toyo Energy Solution Co., Ltd. to help the nation meet its carbon neutrality goals.”
