Waste In, Energy Out: The Costs and Benefits of Anaerobic Digesters Anaerobic digestion is a proven technology, but what are the economic benefits?
نویسنده
چکیده
Credit: Cornerstone Environmental Group Anaerobic digesters are a mature, proven technology. They take sludge, manure, and other organic waste materials and produce methane (natural gas) fuel. Nobody questions their technological capabilities. However, the question remains as to their economic benefits. In terms of dollars and cents, how much economic sense do anaerobic digesters make? What are the economic benefits of an anaerobic digester fuel system? Under what scenarios do they make sense, and under what scenarios are they of only marginal benefit—or should not be considered at all?

Anaerobic digestion can be used to convert organic waste into energy not only to provide renewable energy, but also reduce greenhouse gases. During the anaerobic digestion process, biogas is produced, which can be used for heating and electricity generation. The produced biogas contains methane and some other gases, the most destructive of which is hydrogen sulfide gas. If hydrogen sulfide gas ...
