Current model of construction industry follows a linear path - material serves a singular life cycle from extraction to demolition. Society’s infinite demand for infrastructure and architectural development has made the industry a major factor in the global environmental crisis. Currently, the concrete industry alone accounts for 8% of the CO2 emission around the world. If it were a country, it would be the world’s third largest CO2 emitter right after China and the US.

Project Alternative Concrete advocates for a circular path, in which architecture can serve multiple lifecycles through both material recycling and adaptive reuse. Four types of innovative concrete materials will be introduced, and their methods of application explained. The aim of this website is to serve as an open source of information for the public to understand the properties of such innovative materials, and to promote its applications in designing for a circular economy.
