Anaerobic Digestion Technology (ADT)

Indiana generates approximately  9.51 million tons of animal manure  and tremendous amount of other organic wastes, which could negatively affect water and air quality. Anaerobic digestion can convert these wastes to renewable energy, reduce environmental pollution and greenhouse gas emissions, and generate economic and multiple social benefits.

Application of anaerobic digestion technology in Indiana has been accelerating. Since the first agro-industrial digester system was built in 1997 and the first manure digester system was built in 2002 in Indiana, there are now 13 systems in operation and one under development.

The current anaerobic digestion systems in Indiana approximately generate 30 MW power and reduce carbon dioxide emissions by >280,000 tons per year. The potential energy from animal manure alone is equivalent nearly 10 billion cubic feet of natural gas per year.

This website is designed to provide brief technical, economic, environmental and regulatory information related to anaerobic digestion.
