Chapter 2: Waste Management in Carpentry Projects
Construction, Renovation, and Demolition (CRD) Waste
Construction, renovation, and demolition activities are one of the major waste contributors to landfill sites.
Did you know?
- It is estimated that the construction industry in Canada generates about 9 million tons of CRD waste annually.
- The CRD waste generated by the Canadian construction industry accounts for 27% of the total municipal solid waste disposed in landfills?
Over 75% of what the construction industry generates as waste has a residual value, and therefore could be recycled, salvaged and/or reused? (Yeheyis et al. p.81)
What is CRD Waste?
CRD waste, despite potentially containing similar materials, can greatly differ in terms of volume and composition depending on the location and time of year. This variation has important implications for waste management. To categorize CRD waste, Guy Perry and Associates and Keller Environmental (2015) have separated it into three distinct streams.
