Organic Waste to Resources Research and Pilot Project Report: Converting Washington Lignocellulosic Rich Urban Waste to Ethanol
Rick Gustafson, Renata Bura, Joyce Cooper, Ryan McMahon, Elliott Schmitt, and Azra Vajzovic, September 2009. This study investigated the potential of producing ethanol from three primary sources: mixed waste paper, yard trimmings, and a laboratory prepared mixture (50/50 food & paper) representing MSW. Pretreatment consisted of dilute acid hydrolysis (mixed paper and MSW), and steam explosion (yard waste). Ethanol yields of 105, 90 and 55 gal/ton were found for the MSW, mixed paper, and yard waste. A preliminary Life Cycle Assessment showed that overall environmental impacts of ethanol production from MSW are highly beneficial compared to landfill. Conversion of the MSW mixture to ethanol was found to be economically viable.
