Recycling Roofing Materials in Canada 3 rd Asphalt Shingle Recycling Forum November 1 & 2, 2007 Chicago, Illinois Michael Clapham, NRCan

 Overview of C&D recycling  Roofing, Recycling Opportunities  Workshop  Applications  Key Issues  Workshop Results  Activities Resulting from Workshop Outline

The Importance of C&D Recycling Composition of C&D material:  3 – 5 million tonnes disposed in 2002 in municipal or private landfills  Material is usually mixed or contaminated Markets are available for recycled materials:  Metals mostly recycled  Concrete used in road beds (aggregate sub.)  Asphalt pavement largely recycled  Drywall  Old Corrugated Cardboard (OCC)

Three projects related to the C&D sector:  Recycling of construction materials from 15 residential and commercial sites in the GTA (report on Recycling in Canada web site)  Canadian standard for design and disassembly of buildings (  Facilitating greater reuse and recycling of structural steel in the C&D process (report available upon request) Construction and Demolition Initiatives

Roofing Materials Recycling - Opportunities High levels of material recovery  1.25 Million tonnes of residential shingles to landfill every year Significant GHG emission reduction potential  If 5% of total HMA used recycled shingles, 90,000 tonnes of CO 2 emission reductions could be achieved

Workshop held in Toronto February 2006 to identify:  Strategies to shift the flow of end-of-life roofing materials away from landfill  Value added applications  Economic and technical impediments to recycling  GHG emissions reductions are possible via recycling activities  Roles of each key stakeholder Enhanced Recycling of Roofing Materials Workshop

Transportation Surfaces  Need to provide consistently high quality product Energy Recovery  For that which cannot be recovered for its material value Other Uses  Sound proofing products Applications

 Technological  Economic  Social/Market Acceptance Key Issues Addressed at the Workshop

1. Technological  Process  Quality Control  R&D  Performance  Training and Education

 Cost  Value Added  Risk Mitigation  Appropriate End-of-Life Options  New Markets 2. Economic

 License to Operate  Acceptance  Behaviour Change  Communication  Regulatory and Policy 3. Social/Market Acceptance

Implementation Plan will focus on the following areas:  Pilot projects and case studies  Research and development  Best practices and business models  Incentives and regulation  Communication and education strategies Workshop Results

 Potential Implementation pilots in the following municipalities:  Metro Vancouver  Calgary  Region of Peel  Halifax Region (currently recycling)  Pilots for the West and Ontario spring or early summer 2008 Activities Resulting from Workshop

Metro Vancouver  100,000 tonnes asphalt roofing disposed  Expected to increase 4X over next 5 years  Looking for a member municipality to use processed shingles in hot mix asphalt  Need to coordinate with contracting cycles  Need to identify housing projects and storage areas

Calgary  Alberta has made C&D recycling a provincial priority  83,000 tonnes per year asphalt roofing disposed in Alberta  25,000 tonnes per year asphalt roofing disposed in Calgary  Manufacturers off-cuts are being recycled in Edmonton  Calgary to propose a tear-off shingle recycling project next spring

Region of Peel  50,000 tonnes per year asphalt roofing disposed in Peel  C&D waste goes mainly to private landfills  Region is interested in recycling of asphalt shingles  Will explore the possibility of a pilot early next year

Halifax Regional Municipality  12,000 tonnes per year asphalt roofing disposed in HRM, 30,000 tonnes for N.S.  Currently HRM is recovering most of it’s asphalt shingles  Tar and grit into paving  Flake for energy recovery
