Anaerobic Digestion: Unaddressed Opportunity

Anaerobic Digestion: Unaddressed Opportunity

The most common waste-to-energy applications in the U.S. include the combustion of municipal solid waste (MSW), landfill gas-to-energy, and the digestion of farm waste or waste water. An often overlooked waste-to-energy resource, however, is mixed organic waste (for example, food and yard waste) anaerobic digestion (AD). AD technologies comes in a variety of shapes and sizes, so for now, we've used assumptions provided by a dry fermentation (that is a digester that accepts higher-solids waste) technology provider. The U.S. Environmental Protection Agency estimates that in 2008, 250 million tons of municipal solid waste (including organic and non-organic) was generated in the U.S. While 22 million tons of organic waste was diverted for composting, an estimated 43 million tons of organic waste was sent to landfills. The total electric and thermal power (assuming a combined h...
