Anaerobic Digestion (AD)

Anaerobic Digestion

Anaerobic digestion is the process by which microorganisms break down organic (carbon-based) materials, such as food waste, grease, and wastewater solids in the absence of oxygen. This process produces biogas, a renewable energy source, as well as digestate or biosolids, residual materials that facilities can treat and use in beneficial applications. Co-digestion is the simultaneous anaerobic digestion of multiple organic materials in one digester, such as food waste and manure.
EPA Closes Round Six
