Use It Up, Wear It Out : Valorizing Wood Waste in Vancouver BC Nielsen-Roine, Kaia

Abstract

Vancouver has a construction and demolition (C&D) waste problem. We produce about 1.7 million tons of C&D waste every year and of that, 31% is wood waste. Given that about 57% of new buildings in Vancouver are light-wood type buildings, the city needs a strategy to reduce the demands for new wood in new constructions. This project presents a method to recycle salvaged wood from deconstructed light-wood buildings and use those materials in new deconstructable assemblies. Common wood waste such as dimensional lumber, plywood, oriented strand board (OSB), laminated strand lumber (LSL), and laminated veneer lumber(LVL) can be recycled into new wood products including finger-jointed lumber, OSB/LSL or Plywood/LVL crosslam tiles, and wood fibre insulation. To demonstrate the viability of these materials, I constructed a full scale mock up of a wall section that can, in turn, be fully deconstructed and reused or recycled using the proposed recycling technology. This research creates a framework that would help reduce the construction industry’s reliance on new wood material and promote circular reuse and recycling of wood products rather than wasting or downcycling wood to biomass or waste-to-energy fuel.
