The Manure Digester and Biogas Controversy

Manure digesters are a rapidly expanding and hotly debated technology. They work by capturing methane, a potent greenhouse gas, and converting it to a biogas that can be burned for energy. Manure digesters are touted by their proponents as a climate solution, a renewable energy source, and an economic boost for farmers. Opponents argue that manure digesters are a form of greenwashing that distracts from actual climate solutions, worsens air and water pollution, and adds to the health and economic burdens borne by rural communities.
