What is Biogas?
Did you know that feces can be made into a gas that provides electricity? Yes, you read that correctly. Biogas is what’s created when you take manure or other organic matter (even wastewater solids will work) and put it in an anaerobic digester. It can even be created by capturing methane produced by landfills. This makes the matter into a gas which is used for electricity, heat, and even for powering vehicles. Biogas is a promising source of renewable energy because it uses inputs that may otherwise be waste and reduces emissions by diverting methane (a powerful greenhouse gas) from landfills. Even the waste of the waste is useful—it becomes a most excellent fertilizer.
