While a portion of the sludge may be treated and recycled as fertilizer, most facilities dispose of the remainder through landfills or incineration, placing a strain on their operating costs as well as on the environment. Anaerobic digestion is an effective way to reduce organics, including sludge, by converting it to biogas. In some municipalities, anaerobic digestion happens at the [...]
