This study showcases the game-changing potential of recycled wood waste to create high-performance materials like finger-jointed lumber and CLT, combining sustainability, strength, and a circular future for construction.

This research focused on repurposing underutilized lumber waste, which constitutes over 20% of landfill material, by transforming it into blocks for finger-jointing and high-performance cross-laminated timber (CLT). Through systematic material collection, preparation, remanufacturing, and rigorous testing, the study evaluated the structural, durability, and carbon sequestration properties of the resulting CLT. By demonstrating the potential for sustainable reuse, the project advanced circular economy principles and reduced the environmental impact of lumber waste in the construction industry.

Reclaimed lodgepole pine finger-jointed (FJ) boards can meet national quality standards with improved glue and pressure application methods, unlocking the potential for high-performance, sustainable materials in construction.

This study investigates the mechanical properties of finger-jointed lumber made from lodgepole pine deconstruction wood waste. Conducted at UBC’s Centre for Advanced Wood Processing, the project included preliminary and final testing phases to optimize joint design, validate processing steps, and evaluate strength and durability using standardized grading, adhesive application, and three-point bending tests.

“In British Columbia, 74% of construction wood waste ends up in landfills, but with innovative solutions like finger-joining and circular reuse, this valuable resource could fuel a sustainable future while saving builders thousands of dollars per project and shows huge potential.”

This master’s thesis examines recycling opportunities for construction wood waste in British Columbia, addressing the increasing volume of waste wood in landfills. Through interviews with construction companies, waste and recycling organizations, and the analysis of regional waste management practices, the study evaluates the feasibility of reusing wood waste for applications like structural lumber, mulch, or industrial fuels. It proposes an innovative business model that supports a circular economy by diverting wood waste from landfills and identifying cost-effective logistics and recycling methods to reduce environmental impact and create new revenue streams.
