Blockchain Integration for Circular Economy Adoption in Steel Construction

Abstract

PurposeThe circular economy (CE) is an economic model aimed at minimizing waste and optimizing resource use by extending lifecycles through recycling, reuse, and other strategies. This shift from the traditional linear model (take-make-dispose) is crucial for a more sustainable and resilient built environment. Given its environmental impact, the steel construction industry holds significant importance in driving sustainability and CE efforts. This study aims to explore the potential of a blockchain(BC)-based framework to overcome barriers hindering the adoption of CE principles within the industrial steel construction sector, thereby promoting sustainability and circularity in the built environment.Design/methodology/approachA conceptual BC framework is proposed to enable effective recording, storing, and sharing of process-related data among stakeholders throughout the lifecycle of construction materials. The framework's validity is assessed through a focus group study conducted at a steel construction company, involving expert evaluations.FindingsExpert evaluations indicate that the BC-based framework can significantly enhance CE adoption by improving information flow, raising awareness, and fostering collaboration among ecosystem participants.Originality/valueThe study introduces an innovative application of BC technology tailored for the steel construction sector to address specific CE barriers, offering a novel approach that facilitates digital and sustainability transitions.
