Recent data suggests that the total is made up of about 9.4 million tons from roofing tear-offs and about 1.6 million tons from manufacturing scrap. « lessīased on a widely cited September, 1999 report by the Vermont Agency of Natural Resources, nearly 11 million tons of asphalt roofing shingle wastes are produced in the United States each year. The authors are carefully chronicling and optimizing the Bay Area recycling campaign with the intent of promoting similar activities nationwide as soon as the economics become favorable. Other reuse scenarios are being explored.
XNIP 325453A DISTRIBUTOR PATCH
A potentially more profitable reuse of recycled product is in the production of a cold patch for road repair which, when fully commercialized, will further improve the economics of shingles recycling. The product is half-inch minus granular asphalt with co-mingled sand that may be used as a feedstock (approximately 5%) in the production of hot-mix asphalt, as used for road construction. Roofing waste is introduced to the grinder, which processes up to 50 tons per hour. Their approach has been to use a 60 inch x 38 inch rotating-head grinder propelled by a 400 horsepower diesel engine. The authors analyzed impediments and opportunities in recycling asphalt shingles and elected to commence operations in the east San Francisco Bay area, where tipping fees as high as $50 per ton provide an economic incentive to intercept and more » recycle this waste stream. However, in most cases the shingles are landfilled at the local tipping fee. This waste stream generally arrives by truck at local landfills, where it is relatively unmixed and ready for recycling. The wastes from roof removal or repair operations are a promising, but under-harvested feedstock for recycling.
