Recycling Roofing Materials in Canada
3rd Asphalt Shingle Recycling ForumNovember 1 & 2, 2007

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 (www.csa.ca)
Facilitating greater reuse and recycling of structural steel in the C&D process (report available upon request)
Construction and Demolition Initiatives
Carbon dioxide equivalents per kilogram
Drywall 24
Asphalt (RAP) 111
Asphalt (shingle) 60
Clay, brick 3
Concrete 170
Wood 11
Vinyl windows 122
Steel (hot rolled) 1 862
Steel (galvanized) 1 465
Steel (structural) 820
Copper 1 600
C&D Materials; GHG Emission Reductions
Source: Athena Institute
Example:For every one kg. of drywall recycled, the emission of 24 kg. of CO2e is avoided.
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 CO2 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

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
