| Power plants have been designed to produce methane gas by digestion of animal waste. Animal waste includes livestock and poultry manure, dairy wastewater, feedlot runoff, silage juices from silos, and wasted feed. Animal waste reduces the need for commercial fertilizer; it adds organic matter to soil and improves the water holding capacity of the soil. The residue will be recycled. This is recycled by returning it to the farms where it can be used as a fertilizer. Fuel from animal waste is a renewable energy. The source of this energy is plentiful and constant; the waste product is utilized effectively and contributes to the continuous generation of an efficient energy source. |
