Science
Anaerobically digesting organic carbon involves a plethora of naturally occurring bacteria. The many different species of bacteria break down complex organic molecules through a four-phased process: first hydrolysis, then acidogenesis, followed by acetogenesis, and lastly methanogenesis.

The main products of this biological process are biogas and a solid residual. Biogas is comprised mostly of methane and carbon dioxide and can be used as a fuel source.
