Challenge and proposed solution

The project aims to develop returned concrete into a viable alternative coarse aggregate that reduces the carbon footprint associated with quarrying and transportation of virgin aggregate.

The reuse of the returned concrete as aggregate will be a significant contribution to the circular economy, saving annually up to 120,000 cubic meters or 288,000 tonnes of returned concrete from being sent to dumping pits in Australia.
