Proposed Demolition Processing Pilot Project
Demolition Waste Management
Goal: Development and maintenance of a clear long-term strategy for how the County addresses demolition waste management. The following are considerations needing attention: Compliance with State waste management policies
promote waste reduction and reuse promote landfill abatement and resource recovery encourage generator responsibility
Provision of direct services
provide geographically broad-based collection and disposal opportunity transfer collected wastes to an environmentally acceptable and
economically viable disposal facility Sound fiscal management
control/minimize costs borne by taxpayers minimize taxpayers’ liability exposure reserve funding for potential longer term costs charge sufficient fees to fund waste transfer (to extent possible) charge appropriate tipping fees for disposal in facilities
Regulatory compliance
satisfy State environmental laws and regulations prevent environmental contamination address environmental contamination
Fair and equitable treatment of private contractors
avoid unfairly competing with private firms through subsidized fees satisfy state contracting and accounting laws and regulations conduct open processes for securing the provision of services
Improved public education
information to residents on reduction, reuse, and proper disposal information to contractors on proper demolition and haulage
Background• Northwoods Pilot Project – Results presented at MPCA
Conference – 2000
• Re-Use sheds constructed 2006 to Present
• All Concrete, Brick and Blacktop processed as aggregate
2006 - Present
• Shingles Re-use 2007 – 2011
• NMR Pilot Project 4 weeks - 2008
Waste Categories• Wood – shipped to Minnesota Power – Biomass
• Metal – marketed by contractor
• Aggregates – separated, crushed marketed/utilized locally
• Shingles – separated, processed work with Public works and MNDOT
• Cardboard – marketed through recycling center
• Residuals – landfilled at RLF, General Waste and Waste Management

Recommendation• Request SWSC approval
• Request Board approval
• Proceed with 3 Month Pilot Project• Evaluate numbers/success weekly• Continue for additional 3 months based on numbers• Review Contractor Report
• Get MPCA permit modification/approval
• Draft Request for Bids after 6 month project for long term program development.
