Circular economy in construction: current awareness, challenges and enablers

The application of the concept of circular economy thinking in construction, which is in its infancy, has been largely limited to construction waste minimisation and recycling. Little research on circular economy from a systems perspective including how new business models might enable materials to retain high residual values has been undertaken. Utilising the results from a survey and a follow-up workshop, this paper provides an analysis of an industrywide perspective of circular economy awareness, challenges and enablers. The survey results indicate that while there is industrywide awareness of the concept, clients, designers and subcontractors are the least informed and this is a key challenge for greater adoption. The absence of incentives to design products and buildings for disassembly and reuse at their end of life is a significant challenge. To encourage greater implementation of circular economy principles throughout the supply chain, a clear economic case is paramount, supported by metrics, tools and guidance.
