Anaerobic digestion is the natural process in which microorganisms break down organic materials in a sealed reactor without oxygen. Organic inputs may include a variety of materials, such as animal manure, dedicated grassy biomass, food waste, and wastewater biosolids. Outputs include methane-rich biogas and digestate, which may be used to make a variety of products, such as soil amendments, fertilizer, animal bedding, electricity, heat, and vehicle fuel.

A full conference agenda and registration information are available on EPA’s conference webpage.
