Michigan State U opens AD facility
TRASH TO GAS: Fiberight LLC’s waste recycling plant in Marion, Iowa, will produce MSW-derived feedstock for biogas production.
Fiberight to produce compressed biogas Waste-to-energy firm Fiberight LLC could break ground on a waste recycling plant in Marion, Iowa, before the end of the year. The Marion City Council voted unanimously in August to approve a resolution establishing a 15-year waste supply agreement with the company. Once complete, the facility will process municipal solid waste (MSW) into feedstocks for the production of compressed biogas and cellulosic ethanol. Equipment at the plant will separate out recyclable materials from the MSW. The remaining waste

stream is comprised of soluble organics, which will be fed into a proprietary highrate anaerobic digestion (AD) system, and cellulosic materials, which will be processed into cellulosic biofuel at a nearby plant in Blairstown. Biogas generated in the AD system will be compressed for use as transportation fuel. Craig Stuart-Paul, chief executive of Fiberight, estimates the production of bioCNG will begin during the second quarter of next year.
Michigan State University recently celebrated the opening of an anaerobic digestion (AD) facility that will take in waste from its farms and dining halls, creating energy for several campus buildings. The system will take in approximately 17,000 tons of organic waste and generate 2.8 million kWh of electricity per year. The campus is also home to a small AD system used for research purposes. According to Dana Kirk, a specialist from MSU’s Department of Biosystems and Agricultural Engineering who is overseeing the project, approximately 20 percent of the energy produced by the new system is used to sustain the anaerobic digestion process. The remaining 80 percent is available for on-campus use. “This system is the largest on a college campus in the United States,” Kirk said. The MSU AD project is one of four on-campus AD systems highlighted during a recent Biomass Magazine webinar. During the event, Kirk spoke about the university’s Anaerobic Digestion Research Education Center, which was founded in 2008 to provide research, evaluation and education related to integrated AD systems for smalland medium-sized facilities.
