New technique could accelerate waste-to-methane production

In a recent study, environmental engineering master‘s student Bappi Chowdhury and his colleagues found that adding conductive materials to the waste products could potentially turn them into a reliable feedstock, allowing for a production rate of up to 70 percent more biomethane—a renewable energy source—from a mixture of fat, oil and grease and ordinary food waste in an anaerobic digester.
