Organic agriculture is a fast growing sector of the U.S. food industry. According to data released by the Organic Trade Association, total organic product sales hit a new benchmark of $43.3 billion in 2015, which was up 11% from the previous year and much higher than the overall food market's growth rate of 3%. Along with the increase of organic food sales is the growing awareness among the agricultural community that, to achieve a sustainable agricultural system, wastes generated during the cultivation, processing, storage, and transportation of produces must be viewed and used as a resource rather than something to be disposed to landfill. Typical wastes from organic farms are crop residues, cover crop, processing residues, and food wastes, which are rich in plant nutrients and organic matters. This project used a recently developed cartridge style anaerobic digestion system to convert the wastes collected from organic farms into biogas, and evaluated the total potential energy production by using this system.
