Biochemical conversion is a type of conversion technology that turns organic wastes into valuable products using biochemical processes. Processes include aerobic conversion such as composting and anaerobic digestion which occurs in landfills and controlled reactors or digesters. Another example is anaerobic fermentation which converts sugars from cellulose to ethanol fuel. Biochemical conversion proceeds at lower temperatures and lower reaction rates. Higher moisture feedstocks are generally good candidates for biochemical processes.
