Anaerobic Digestion is Green
Farm and factory-based digesters have been heralded by environmentalists for their ability to generate energy without using fossil fuels and to handle waste products that are harmful to the environment.
Widely used in other countries for energy and waste management, the U.S. government is also endorsing digesters. The U.S. Environmental Production Agency’s AgSTAR program is a voluntary outreach and educational program that promotes the recovery and use of methane from animal manure by promoting the use of biogas recovery systems. AgSTAR is a collaborative effort of EPA, the U.S. Department of Agriculture and the U.S. Department of Energy.
According to AgSTAR: “Anaerobic digester technologies provide enhanced environmental and financial performance when compared to traditional waste management systems such as manure storages and lagoons. Anaerobic digesters are particularly effective in reducing methane emissions, but also provide other air and water pollution control opportunities.”
Today, waste management companies are turning to farms and factories that have digesters to process waste from other sources, adding addition income potential.
Sierra Club Magazine’s article “Innovate: Manure to Money” describes how digesters generate energy and profits for farmers.
