Construction and demolition waste accounts for an estimated 20 per cent of the total amount of municipal solid waste landfilled in Calgary. This waste is generated from construction, demolition and renovation activities from both small-scale and large-scale construction projects. It is generally composed of non-hazardous materials such as wood, concrete, asphalt, drywall, metal, roofing materials and cardboard.
In May 2011, City administration provided a progress update on C&D waste diversion to Council. It identified challenges and recommended next steps, which were subsequently adopted by Council. The recommendations were as follows.
- Re-engage C&D stakeholders and work together to identify and overcome challenges, starting in 2011 and continuing into the 2012-2014 business cycle;
- Continue to promote C&D waste diversion through communications and education;
- Continue to monitor C&D waste diversion through communications and education;
- Continue to monitor C&D waste diversion progress and opportunities;
- Continue to explore best practices to identify opportunities relevant to Calgary;
- Transition the Spyhill C&D pilot to regular operations in 2011;
- Expand source-separated C&D collection and diversion to the other two City landfills in 2012-2014;
- Include drywall and recyclable wood on the Designated Materials List in 2012-2014;
- Enhance waste load audits at the City landfills to ensure compliance with the Designated Materials List (2012-2014);
- Continue to work with and advocate for the provincial government to assume a leadership role in C&D waste diversion, and to implement a deposit refund program for construction and waste demolition projects (2012-2014);
- In the absence of a provincial program, develop a proposal for a deposit refund program for C&D projects at the municipal level in consultation with construction and waste demolition stakeholders that could be implemented in 2015-2017;
- Collaborate with The Province and industry to address the need for a baseline study and improve data reporting (2012-2014); and
- Report back to Council by March 2014 on the progress of C&D waste diversion in Calgary.
