Cost incentives encourage post industrial recycling Asphalt shingles contain similar raw materials as hot mix; asphalt, glass mat, granules and limestone stabilizer
Recycled plant waste hardly makes a dent - Annually an estimated 10 million tons of asphalt shingle tear-offs are disposed as landfills - Annual plant waste is reported to be about 1 million tons
Adding tear-offs from re-roofing has its challenges - Tear-offs usually contain various contaminants – nails, wood, demolition debris, household refuse, and in very rare occasions asbestos… - Some state DOTs require pavement standard for nonroad applications - Hot-mix plant operator preference for adding recycled asphalt shingles varies - Logistics to collect and transfer re-roofing tear-offs to hot-mix plants lacks widespread workable infrastructure
Intellectual property field is active - 17 patents and patent applications (1978 – 2007) were identified that reference products made from recycled shingles • • composite board, ground cover, pavement, patching… - Separately 26 patents and patent applications (1978 -2007) made claims for methods to recycle shingles • • shredding heating & milling hydrocarbon recovery size reduction & mixing in hot asphalt/oil
