The Minnesota Pollution Control Agency conducted a study in 2019 to assess the generation and composition of Construction and Demolition (C&D) materials originating in Minnesota and disposed with permitted solid waste facilities with C&D disposal areas in Minnesota. The research included two seasons of material composition at seven facilities across greater Minnesota and the Twin Cities. MSW Consultants was contracted through a competitive process to conduct the study. This presentation will cover the goals, methodology and results of the project, as well as how the MPCA is using the output for future planning in more sustainable “built environment” material management statewide.
