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
