Asphalt shingle recycling documents shared by CMRA

The Construction Materials Recycling Association (CMRA) has released two important documents relating to asphalt shingle recycling: A Best Practices Guide and the Environmental Issues Associated With Asphalt Shingle Recycling. Both documents were created under a grant from Region 5 of the United States Environmental Protection Agency (EPA).

The Best Practices Guide outlines techniques to recycle the shingles, including suggested acceptance standards, testing systems, processing systems, and end markets. It also includes information on specifications for various markets. It was compiled by Dan Krivit, Dan Krivit & Associates.

The Environmental Issues Associated with Asphalt Shingle Recycling document tackles the questions regulators have about the recycling of the shingles, especially the question of asbestos in the shingles. Written by Dr. Timothy Townsend of the University of Florida, it explains how only a small amount of shingles were manufactured with asbestos in them, it contains suggested testing protocols, and explains what regulators might consider when regulating shingle recycling centers.

Both documents are available in pdf format from the CMRA’s revamped website,
