Bio-fermentation

 

Bio-fermentation

Bio-fermentation is the in-vessel fermentation of the organic parts of waste streams to produce methane (for power generation) and simultaneously stabilize putrescible wastes. This process is receiving renewed interest as a method of pretreating and stabilizing putrescible or organic wastes to recover methane. The residues can then be aerobically composted. The energy recovered is hoped to be enough to run the overall plant. As a volume-reduction technique, only about 7 to 10% of the material in the waste stream will be affected by biodegradation without a prior hydrolysis process to convert the ligno-cellulosic material into fermentable sugars.
