ABSTRACT: Buildings and infrastructure (e.g. roads, bridges, power station, wastewater treatment facilities, etc.) provide necessary functions to the residents of a community and city. The circularity performance of building and infrastructure, and their components will largely affect the sustainable communities and cities. The depletion of natural resources has attracted wide attention globally. The last decades have witnessed the strong push from various stakeholders (e.g. public, government and industry) towards more circular economy than linear economy. The traditional approach of make-use-disposal has attracted significant criticism while a close-loop approach has gained an increasingly level of recognition. As one of the largest consumers of natural resources, buildings and infrastructure have a major role to play in circular economy. A circular economy oriented building and infrastructure plays a significant role in achieving sustainable cities and communities (SDG 11). This presentation will showcase some practices in South Australia that aims to achieve circular buildings and infrastructure.
