Produced 20.2 MW of renewable electrical generation at the Waste to Energy and South Kent Landfill Gas to Energy facilities producing enough electricity for 15,000 homes. Completed a five year-review at the Recycling and Education Center to verify facility performance efficiency against original design criteria, baling capacity, quality of recovered materials, labor and other operating costs, equipment maintenance and refurbishment to determine service fees needed to sustain operations. Participation in the West Michigan Sustainable Business Forum - Economic Impact Potential and Characterization of Municipal Solid Waste in Michigan study which determined that $32M worth of materials going to landfill every year. Completed three projects at the closed Kentwood Landfill required by USEPA 5-year review including installation of a gas collection/ flare system to prevent migration of methane to City of Kentwood facilities, installation of additional leachate collection piping to capture leachate on the southern extension and a leachate collection pumping optimization study to help identify system improvements to improve leachate removal. In partnership with manufacturers in West Michigan, completed a Review of Opportunities for Zero Waste to Landfill for Industries study to quantify volumes and types of industrial wood waste and methods and technologies used to divert this material from landfilling. In partnership with Goodwill Industries, fully implemented the Transitional Work Force program to staff the process line at the Recycling and Education Center. Expand promotion of DPW programs to minority and under reached communities by providing new bilingual materials and partnering with the West Michigan Hispanic Chamber of Commerce. (High Quality of Life). Partner with two municipalities to offer public space recycling pilot programs for parks and/ or large-scale community events. (High Quality of Life). Increase single stream recycling volumes for the Recycling and Education Center and process 40,000 tons of material. (Efficient Use of Resources). Partner with 5 neighboring counties, the City of Grand Rapids and waste and recycling service providers to develop consistent residential curbside recycling messaging to improve quality. (Efficient Use of Resources, High Quality of Life). Maximize commodity revenues with market rate service fees to sustain Recycling and Education Center operations. (Stable Revenues). Complete concept of design study for Recycling & Education Center property for suitability of a SafeHome Service Center for household hazardous waste, small quantity generator business waste, electronics recycling and community reuse programming. (Efficient Use of Resources, Safe Community). Increase South Kent Landfill disposal air space within the existing permitted footprint through a facility redesign and use of mechanically stabilized earth wall technology to increase air disposal capacity by 1 million cubic yards. (Efficient Use of Resources). Improve Waste to Energy facility efficiency by 4%, lower HHV by 5%, and increase plant availability to 95 percent by optimizing operations and maintenance practices, diverting recyclable materials, and continuing plant refurbishment capital expenditures. Ensure long term power purchase arrangements are in place with Consumers Energy beyond (Stable Revenues, Efficient Use of Resources). Continue the long term stewardship and management of closed landfill facilities including cap integrity, leachate collection and gas management systems evaluation for the North Kent Landfill and improve leachate pumping capabilities at the Kentwood Landfill in.
