Schools, campuses, food and beverage producers, and food banks all produce thousands of pounds of food waste each year, and typically have to pay to have the waste hauled to a central location such as a landfill. In landfills, organic matter breaks down and produces methane, a potent greenhouse gas that, if captured, can be a valuable source of energy. Enter Impact Bioenergy: the company’s small anaerobic digester systems, or microdigesters, convert food waste and other organic matter like paper and yard clippings into fertilizer and energy in the form of electricity, heat, and even transportation fuels.
