A review of the circular economy approach to the construction and demolition wood waste: A 4 R principle perspective

Abstract

The production of construction and demolition wood waste (CDWW), which is the name for all the wood that will eventually end up in some landfills, presents significant ecological and environmental risks due to its hazardous nature. With a focus on the 4Rs—Reduce, Reuse, Recycle, and Recover—this study explores the application of the circular economy (CE) to CDWW. For ecological sustainability and carbon footprint reduction, the CE method encompasses any strategy that also minimizes waste production and maximizes resource recovery. This research investigates a range of wood waste categories, including Preservative Treated Wood Waste, Engineered Wood Waste, and Untreated Wood Waste (UWW), while proposing suitable methods for managing them sustainably. Better resource efficiency, economic resilience, and environmental protection are provided by this study's observation of CE. This study outlines how CE can lead to more equitable consumption and reduced greenhouse gas emissions by improving resource efficiency, economic resilience, and environmental protection. The results demonstrate that there is sufficient potential for addressing the waste disposal issue and resolving sustainable development issues through the integration of CE in CDWW management.
