Roughly 13 million tons of shingles waste is generated each year, with about 90 percent of it landfilled and taking about 300 years to decompose.
Much of the small percentage that is recycled is incorporated into pavement. But roofing manufacturer GAF, who cranks out a large share of these shingles at its 35 manufacturing plants across North America, plans to recover more of this product at the end of its life, and for a higher use than paving materials.
