The Minnesota Materials Exchange is the waste-not classifieds especially for:
- Minnesota businesses
The Materials Exchange is a free service that links organizations that have reusable goods they no longer need to those who can use them. This business reuse network helps prevent usable materials from becoming waste and saves users money.
The program is operated as part of the Minnesota Technical Assistance Program (MnTAP) at the University of Minnesota. MnTAP provides tailored pollution prevention and energy efficiency solutions for Minnesota businesses.
