Recirculation of construction and demolition Waste: A case study of Danish producers and demolishers

Abstract

As resource scarcity increases, the construction industry recognizes the potential of Reverse Logistic Supply Chains (RLSC) for demolition waste. Implementing RLSC, however, lacks maturity and poses challenges due to the complexity of the construction industry. This paper is the first to investigate the critical interface between demolishers and producers. In particular, demolishers are crucial for the potential to valorize reclaimed construction wood as they are the gatekeepers of the materials. We apply an existing framework, conceptualized through a systematic literature review, to the case of a Danish shed producer and their collaboration with demolishers. Our data foundation includes qualitative data from semi-structured interviews with industry stakeholders and quantitative financial data on conventional as well as selective demolition. Through the analysis of material, information, and financial flows of reclaimed wood, this paper identifies inhibitors to these flows and reveals that producers can address the majority. Since responsibilities for reprocessing, transportation, and storage require clarification, making agreements for (1) reprocessing and (2) transportation, potentially facilitated by (3) a digital platform can support the producer in overcoming these inhibitors. Even though we show that selective demolition can be financially attractive for demolishers, our findings call for additional supportive regulation of tender practices. Further, we coin the concept of reversed value proposition as RLSC necessitate a reversed understanding of value creation. Overall, this paper contributes empirical evidence to the existing framework, extends it by adding inhibitors and flows, and suggests an extension with platform thinking to support the implementation of RLSC.
