ANAEROBIC DIGESTION

Anaerobic digestion is a series of biological processes in which microorganisms break down biodegradable material in the absence of oxygen.

One of the end products is biogas, which is combusted to generate electricity and heat, or can be processed into renewable natural gas. A range of anaerobic digestion technologies are converting livestock manure and various other organic waste streams into biogas, 24 hours a day, 7 days a week.

Separated digested solids can be composted, utilized for dairy bedding, directly applied to cropland or converted into other products. Nutrients in the liquid stream are used in agriculture as fertilizer.
