Blockchain Enhanced Construction Waste Information Management: A Conceptual Framework

Despite the large quantities of secondary materials flowing within built environment, their actual volume and respective waste management processes are not accurately known recorded. Consequently, various sustainability material efficiency policies supported by accurate data information-reporting associated with materials’ availability sourcing. Many recent studies have shown that integration digital technologies such as city information (CIM), building modeling (BIM), blockchain potential to enhance construction (CWM) classifying recycled creating value from waste. However, there is insufficient guidance address challenges during process CWM. Therefore, research reported in this paper aims develop a blockchain-enhanced conceptual framework (BeCW). This first attempt apply strengths integrated information-management optimize CWM, which includes WasteChain for providing unified trustworthy credit system evaluating construction-waste-recyclability stakeholders. enabled through use self-executing smart contracts clarify responsibility ownership relevant As result, study provides explicit referencing quantifies value-contribution stakeholders waste-recovery optimization reuse recycling. It also addresses issue sustainable CWM exchange at four levels: user, application, service, infrastructure levels.
