ASPHALT SHINGLE RECYCLING
Approximately 10 million tons of waste asphalt shingles are generated each
year through reroofing activities in the U.S. Manufacturing produces another
1 million tons of asphalt shingle scrap per year. Asphalt shingles consist of
a felt mat, either organic (cellulose paper) or fiberglass, asphalt, small rock,
ceramic coating and a mineral stabilizer. In some older shingles, a small percentage
of asbestos may exist creating a handling concern. Most waste shingles and scraps
can be processed, generally by grinding, and recycled by a number of road, fuel
and shingle markets.
Shingle Recycling Org is a comprehensive
overview of asphalt shingles, recycling opportunities and regulatory issues.
The website is intended to assist those interested in asphalt shingle recycling
activities by providing pertinent information and contacts. It includes a discussion
of recycling markets, links to current reports and articles, a list of state
regulatory contacts, and a summary of specific state studies regarding highway
and trail pavement applications. Department of Environmental Engineering
