FHWA has a well established materials recycling policy that has evolved for more than 10 years. One related FHWA initiative to build teams and external partnerships is entitled “Focus Area Leadership and Coordination” (FALCON).
FHWA policy provides that recycled materials should get first consideration in overall materials selection
Restrictions prohibiting recycled material that are without technical basis should be removed.
POLICY & EDUCATION:
Kimberly Cochran, PhD, U.S. EPA Office of Solid Waste: 703-347-8950,
EPA intends to improve measurement of C&D recycling and asphalt shingles recycling in particular, including a measurement tool specifically for contractors. EPA has a broad, national initiative entitled the “Resource Conservation Challenge” (RCC)
Cochran (2006) study includes estimate of global warming advantages of asphalt shingle recycling
Randy McMullin, Maine Department of Environmental Protection 207-822-6343,
New England has high landfill disposal fees at $65 to $100+ per ton
Tear-off shingles in Maine, in part, are source separated for recycling and deposited for tipping fee at about $32 per ton
Some tear-off shingles are collected at town transfer stations and come primarily from roofing contractors; however, citizens can also bring shingles to the processing facility or transfer station facility.
Primary end markets include: HMA (2% RAS) and unbound aggregate (50% RAS). Other uses such as fuel supplement under development.
Environmental impacts assessment from multiple analyses: conclusions:
Sampling for asbestos is no longer required in Maine, however, asbestos sampling requirements for the incoming whole tear-off shingles and outgoing tear-off RAS product vary by state Asbestos has minimal risk based on a brief mention of the Chelsea Center’s shingle recycling studies ( and ) and summary of results.
