2013 Statewide Waste Characterization Executive Summary <br />1.0 EXECUTIVE SUMMARY <br />The Minnesota Pollution Control Agency (MPCA) retained Burns & McDonnell, Inc. in conjunction with <br />MSW Consultants and GRG Analysis, (Project Team) to conduct a Statewide Waste Characterization <br />Study (2013 Study) to assist the MPCA and local governments with their planning efforts associated with <br />managing municipal solid waste. <br />The Project Team developed a methodology for gathering representative data related to the composition <br />of the mixed municipal solid waste disposed in Minnesota. The methodology included the following <br />steps: <br />• Determine material categories and definitions; <br />• Identify and recruit host facilities; <br />• Develop the sampling and sorting methodology; <br />• Conduct waste sort events; <br />• Analyze collected data; <br />• Complete statistical modeling; and <br />• Develop the composition results. <br />The six facilities that agreed to host field sampling and sorting events included the following: <br />• Lyon County Regional Landfill; <br />• Hubbard County South Transfer Station; <br />• Western Lake Superior Sanitary District Transfer Station; <br />• Elk River Resource Recovery Facility; <br />• Pine Bend Landfill (Republic /Allied); and <br />• St. Paul Como Transfer Station (Advanced Disposal). <br />The above facilities were selected because of their interest in the Study, geographic representativeness of <br />their waste streams, and the varying types of mixed municipal solid waste facilities represented. <br />A set of fifty (50) material categories was identified for sorting. The definitions of each of these material <br />categories are included in Appendix A for reference. <br />Provided below in Figure ES -1 are the aggregated statewide waste composition results by primary <br />material category. <br />Minnesota Pollution Control Agency <br />1 -1 Burns & McDonnell <br />
