Biodigesters and Biogas
"Anaerobic digestion, or biodigestion, involves the microbial degradation of organic materials in an oxygen-free environment. Feedstocks for anaerobic digestion include livestock manures, crop residues, culled fruit and vegetables, food waste, and other organic by-products. The process produces renewable energy in the form of biogas (which is mostly methane) and a nutrient-rich digestate that can be used as a biofertilizer instead of commercial fertilizers."
-- Dr. Ann Wilkie, Professor of Bioenergy and Sustainable Technology in the Soil and Water Science Department at the University of Florida

Key Resource1/01/2001 When organic material decomposes under anaerobic conditions, it produces biogas which is a mixture of methane (CH4) and carbon dioxide (CO2) with small quantities of hydrogen, nitrogen, carbon monoxide and other compounds. Biogas can be used as a fuel source for cooking, heating, producing light...
