The Energy Resources Center (ERC) focuses on promoting anaerobic digester technologies as an alternative energy source across the Midwest. Through targeted education and partnerships with state energy offices, the ERC provides comprehensive resources to help stakeholders implement anaerobic digestion systems. These systems effectively convert organic waste from agriculture and food processing into biogas for energy, compost materials, and liquid fertilizers. Since 2004, the ERC has organized numerous workshops and assessments, leading to over 40 installations of biogas-fueled combined heat and power systems, generating over 37 MW of clean energy.

Anaerobic Digester Alternative Energy Technologies Investigators: John Cuttica, Steffen Mueller, Cliff Haefke (Energy Resources Center) Primary Grant Support: U.S. Department of Energy, Blue Moon Fund, Illinois DCEO • Anaerobic digesters provide the necessary conditions to foster the natural occurring decomposition of organic matter by bacteria in the absence of oxygen. • Anaerobic digestion provides an effective method for treating the waste products from livestock farming, food processing, and waste water treatment industries into: • Biogas that can be used to provide heat and/or electricity, injected into the natural gas pipeline, or converted to a compressed or liquid transportation fuel • Solids (fiber) that can be used as compost, animal bedding, granule fertilizer, and/or medium density fiberboard • Liquid (filtrate) for liquid fertilizer land application Source: US EPA AgStar • The ERC fosters anaerobic digester alternative energy project identification and implementation in the 12 state Midwest region through targeted education, unbiased information, and technical assistance. • The ERC, working closely with each of the State Energy Offices and State Agriculture Departments, has formed partnerships with the anaerobic digester stakeholders in the Midwest. • The ERC has implemented a full gamut of outreach services, including web site, targeted market workshops, project profiles, site technical and financial analyses, and specialty reports. • Since 2004, the ERC has co-organized and/or co-sponsored 10 waste-to-energy workshops on anaerobic digester technologies and their market applications in the agriculture, food processing, and wastewater treatment industries reaching over 1,200 interested attendees: IA (2), IL (2), IN (3), OH (2), and MI (1). • The ERC has completed 10 technical feasibility assessments and 12 project profiles on anaerobic digester alternative energy projects. • The Midwest has experienced an increase in anaerobic digester/biogas fueled CHP systems – over 40 installations totaling more than 37 MW of clean power
