The Environmental Protection Agency and its partners have released guidance that can help farmers manage livestock waste and boost farm earnings while reducing greenhouse gases. Processing livestock manure under controlled conditions can produce biogas, a source of greenhouse gas emissions, EPA said today.
Farmers also benefit because the biogas can be used to generate electricity. "Using biogas has multiple benefits; it decreases greenhouse gas emissions, produces renewable energy for rural communities, and safeguards local air and water quality," said Bill Wehrum, EPA's acting assistant administrator of air and radiation. "This guidance will help farmers and potential investors make informed choices about which systems work best for farms, for profits and for our environment."
The standardized guidance was developed jointly by EPA's AgStar program, the Association of State Energy Research & Technology Transfer Institutions and the U.S. Department of Agriculture. The guidance will provide a standardized method that will allow farm operators and investors to compare the effectiveness of available waste methane recovery systems.
