Project status: Research and development is underway

Project partners: UBC Chemical Engineering, FPInnovations, Metro Vancouver, INRS (Institut national de la recherche scientifique) and others

Project description: Metro Vancouver and regions across Canada and the US are progressively banning construction and demolition (C&D) waste from landfill. Clean wood is easiest to divert and can be readily repurposed, but glued, resinated, painted or treated wood are more difficult to handle after their useful life. These difficult materials represent up to 60% of all C&D materials being disposed, so decontaminating treated wood and identifying end markets is an important opportunity to enable these bans to go forward.

The Institut national de la recherche scientifique (INRS) in collaboration with FPInnovations has developed a process to remediate wood treated with the preservative chromated copper arsenate (CCA), and wood treated with other preservatives. This project would look into the feasibility of managing post-consumer treated wood using this method with existing infrastructure and operations, and assess potential business models including end markets in the Metro Vancouver area, given local conditions.

Engagement opportunities: This project is open to further collaboration with industrial partners who manage post-use disposal of treated wood.
