Shingle Recycling

With over 150,000 tons of old roofing shingles from roof replacements (tear-off shingles) and from shingle manufacturing companies disposed in landfills each year, the opportunity to recycle shingles in hot-mix asphalt can save money, maintain pavement quality, and conserve natural resources such as petroleum.  For information on how to recycle tear-off shingles or manufactured-shingle scrap into pavement, click through the links below.

About the Shingle Scrap Recycling Project

The SWMCB Manufactured Shingle Scrap Recycling Project is intended to expand the market for this emerging recycling opportunity by improving information and technology exchange. The Manufactured Shingle Scrap Recycling Project is building upon ongoing research and development efforts by the Minnesota Department of Transportation (Mn/DOT) and the Minnesota Pollution Control Agency (MPCA). Some of the original research was funded by these two state agencies more than 12 years ago. This information is provided as a public service and is not intended to be an endorsement of any business, organization or service. For additional listings, check your local phone directory.
