Energy integrated farm operation with recovery of animal feed from food waste

摘要

A method of operating an energy integrated farm operation with recovery of animal feed from liquid food waste is described and claimed. The method involves extracting methane gas from animal manure and using the methane gas to power an electrical generator. The electricity from the generator and the methane gas itself may be used to operate a dryer. The dryer is used to dry a liquid food waste stream to yield a dry food product. The dry food product recovered has enough nutritional value to be useful as animal feed.
