Circular Construction Principles: From Theoretical Perspective to Practical Application in Public Procurement

This paper aims to highlight the role of government and other public authorities in promoting the implementation of circular economy principles in the built environment. Circular construction ecosystem is based on circular building design and the coordinated action of stakeholders along the value chain. Government and local authorities have a special role to play in the built environment as they manage infrastructure and act as regulators and enablers as well. Moreover, circular building design strategies should be encouraged through the government policy tools like public procurement allowing public authorities to formulate tenders that incorporate circular economy principles when purchasing goods, services, and works related to the built environment. The case studies presented show that public procurement can be a valuable tool for promoting circular use of materials and reducing waste, encouraging the construction of circularly designed zero-emission buildings, and stimulating market innovation that reduces the environmental impact of construction while providing benefits to society. Thus, public authorities can be a powerful force driving change and innovation in the construction industry towards more circularity in the built environment.
