What makes a good reuse supplier? Challenges, characteristics and capabilities in circular construction

Abstract

The construction industry in Sweden is a major contributor to national carbon emissions and waste generation, leading to increased attention towards sustainable practices such as reused construction materials. This thesis investigates the role of traditional suppliers in the emerging reuse market. By combining a comprehensive literature review with the empirical findings from 17 interviewees across both construction materials suppliers and contractors, the study explores the challenges, expectations and capabilities required for suppliers to effectively integrate reused materials into their operations. The results show that reused materials differ from new materials in terms of supply predictability, quality assurance and regulatory clarity. While traditional suppliers possess logistical and procurement infrastructure, they often lack the systems and standards needed to manage reused materials. Clients are increasing their demand for circular products, yet the current sourcing of reused materials remains fragmented, informal and unsystematic. Contractors emphasised early planning, standardisation and clearer definitions of what reuse entails, distinguishing between “saved” materials and “pure” reuse. The report identifies key supplier characteristics needed to compete in this field, such as the ability to offer reliable quality assurance and collaboration in early design and deconstruction phases. Additionally, suppliers must develop capabilities for managing certifications, logistics and proactive sourcing through partnerships. The thesis concludes that while challenges remain, traditional suppliers can play an important role in scaling up reuse, provided they invest in internal capabilities and strategic alignment with client demands and circular construction goals.
