The report outlines opportunities for industrial symbiosis in two Cape Town industrial zones. In Montague Gardens, it highlights the reuse of boiler ash in brick making, the need for treated wood waste solutions, and the potential to shift freight from road to rail. In Atlantis, it identifies opportunities for reusing foundry sand and ash, recovering precious metals from e-waste, and investing in waste-to-energy infrastructure such as pyrolysis and gasification plants. The document argues that establishing a central management body and fostering collaboration on shared services and material exchanges are essential for building business resilience and creating low-carbon zones.

The project achieved a 90% reuse rate of demolition waste by carefully deconstructing existing buildings on a 15 ha site. By reusing 4,500 m3 of concrete onsite for fences, casting beds, and pipes, the project saved R649,000 in material and transport costs. Other recovered materials included 3,500 m3 of brickwork for a local school, 2,600 m3 of asphalt, and 6,800 m3 of laterite. The approach avoided greenhouse gas emissions linked to virgin material extraction and processing, with only PVC piping, roof insulation, and sheeting sent to landfill.
