ASPHALT SHINGLES WASTE MANAGEMENT IN THE NORTHEAST
FACT SHEET
February 2007
Background
Asphalt shingles make up roughly two thirds of the U.S. residential roofing market. They are made of the same four basic materials contained in hot-mix asphalt used in road construction. These materials include: fiberglass or cellulose backing (2-15%); asphalt cement (19-22% on a fiberglass-matt base, 30-36% on a cellulose-felt base made with paper); sand-sized, ceramic-coated natural rock called aggregate (20-38%); and mineral filler or stabilizer that includes limestone, dolomite and silica (8-40%). The asphalt used in shingles is made through the partial refinement of petroleum.i
Each year, the U.S. manufactures and disposes of an estimated 11 million tons of asphalt shingles. Of this waste, ten million tons is from installation scraps and tear-offs from re-roofing and one million tons from asphalt shingle manufacturers.ii The U.S. Environmental Protection Agency estimates that shingle waste makes up 8% of the total building-related waste stream and 1-10% of annual construction and demolition debris (C&D).iii
As a substantial portion of the C&D waste stream and because they are usually separated from other debris, asphalt shingles have the potential to be recycled. In addition, technology has created some money-saving opportunities for recycled shingle markets. Using hot-mix asphalt with only 5% recycled shingle material can save $1 - $2.80 per ton of hot-mix asphalt, as well as improve the quality of hot-mix asphalt used in paving."
