ABSTRACT:
A passive waste collection system including a trough disposed to collect animal waste having an adjustable end baffle for controlling the depth of the accumulated waste therein. Any fermented waste spills over the baffle onto a spring-biased valve and when the waste load on the valve exceeds the spring bias, the valve opens to permit the transfer of the waste to a fermentation tank. The ullage of the fermentation tank in turn communicates with an accumulator to collect the fermentation gases for use in the production of energy.
