Going from “rot to watt,” or turning farm waste into electricity, is the goal of a Washington State University (WSU) project that has just received a $100,000 boost from the Washington Department of Ecology (Ecology). WSU will use the money to finish building a portable anaerobic digester that turns farm waste, manure and household garbage into methane gas that can be burned to generate electricity. The anaerobic digester is being developed by WSU’s biological-systems engineering department. It will be transported around the state to demonstrate how the new technology can generate power while helping to solve solid-waste disposal problems.”This is an example of how Ecology … » More …
