Design for Circularity (DFC) in Construction: A Mini-scoping Review of the Strategies

Design for Circularity (DfC) is an approach that seeks to optimize materials and resources in construction projects to minimize waste generation and thereby extend the lifecycle of materials used. Conventionally, the construction industry (CI) is known for employing linear economy practices, which consume vast virgin resources, large amounts of energy, and high quantities of waste. Therefore, circular design must enable a smooth transition to a circular economy (CE) for positive resource use and efficiency. This study is a mini-scoping review aimed at investigating the key DfC strategies linked to the Circular Economy (CE) concept used in the construction industry and employed by design professionals. The methodology adopted the five-step process by Arksey and O’Malley. It used PRISMA for data organization, leading to the final list of articles used in the mini-scoping review. The mini-scoping review identified several key strategies employed to design for circularity in the construction industry and was discussed with relevant studies provided. This study gives insight into DfC as an increasingly important concept that can reduce the construction industry’s ecological footprint, requiring further development and research to maximize its effectiveness. Thus, it is further suggested that future research emphasizes identifying new DfC strategies, developing existing ones, and integrating existing strategies in the construction industry processes. Again, there is a need for further collaboration between design professionals and other CI stakeholders to ensure that these strategies are prioritized to reduce waste and optimize materials resource usage.
