Blockchain-based framework for improving waste management and circular economy in construction

There is a current lack of management tools that guarantee control and traceability of actions taken by the generator of construction and demolition waste (CDW). Furthermore, the reinsertion of recycled CDW into productive cycle is necessary to foster a circular economy in construction sector. To address these challenges, this study builds a novel blockchain-based information management framework for CDW management in construction, which extends the applications of blockchain for improving circular economy in the sector. Using design science research as a methodological research strategy, this study presents and analyses a blockchain framework and its development processes. The framework performance was evaluated through simulation and quantitative and qualitative indicators. Through a SaaS (Software as a Service) concept, the system allows strengthens the connection between stakeholders looking for sustainable solutions for CDW management. These solutions are independent of the size or segment of the company and allow the creation of business opportunities within the industry itself that provide expertise to foster the circular economy such as reverse logistics, servitization, and industrial symbiosis.
