Abstract/Summary

Purpose: The circular economy 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 circular economy efforts. This study aims to explore the potential of a blockchain-based framework to overcome barriers hindering the adoption of circular economy principles within the industrial steel construction sector, thereby promoting sustainability and circularity in the built environment. Design/methodology/approach: A conceptual blockchain 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. Findings: Expert evaluations indicate that the blockchain-based framework can significantly enhance circular economy adoption by improving information flow, raising awareness, and fostering collaboration among ecosystem participants. Originality: The study introduces an innovative application of blockchain technology tailored for the steel construction sector to address specific circular economy barriers, offering a novel approach that facilitates digital and sustainability transitions.
