Renewable Energy Alternatives

Anaerobic digestion of manure with food processing waste resulted in renewable electricity production for 190 house and reduced 81% of greenhouse gas emissions from manure management. The solids were separated from the manure for composting, with the digester effluent injected into the soil as a fertilizer. This FactSheet is part of the ‘Animal Waste Technology’ series.

Anaerobic digestion is a process where anaerobic bacteria break down organic material to produce biogas. This process occurs naturally in various environments and can be used in anaerobic digesters to treat and dispose of waste, generate biogas, and destroy pathogens. The biogas produced consists mainly of methane and carbon dioxide, with trace levels of other gases.
