Enhancing circularity of wood waste through deconstruction in building sector

Although existing literature extensively explores recycling and reuse in construction and demolition waste, there is a notable gap in research specifically focused on wood waste circulation through design for deconstruction (DfD). This paper presents a comprehensive literature review, examining 41 studies to explore three major aspects of wood waste circulation: its environmental, economic, and social impacts; the reuse of deconstructed wood materials; and the challenges and recommendations for future wood waste circulation through DfD. The review reveals a more than 50% reduction in greenhouse gas emissions through wood material reuse and recycling, highlighting the significant environmental benefits of deconstruction and material recovery across various regions and scenarios. The social impacts include job creation, community engagement, educational opportunities, and cultural preservation, further demonstrating the holistic benefits of deconstruction. The economic impacts are mixed due to varying labor, disposal costs, and salvage values. Identified research gaps include labor intensity, economic, technical and social barriers, policy constraints, and quality issues of reclaimed wood. The paper concludes with recommendations for future research, emphasizing the need for policy refinement, innovative deconstruction techniques, interdisciplinary collaboration network, and market expansion strategies to enhance the adoption of sustainable construction practices in the wood industry.
