The use of C&D materials in Cape Peninsula
Internationally, the recycling and reuse of construction and demolition (C&D) wastes are recognised construction industry practices with established markets in the EU, USA and Australia achieving C&D recycling rates of 70% - 90%. Only recently has the South African environmental management framework formally introduced recycling into our national legislative environment. These regulations have created obligations “for the generation, minimization, storage, recycling, collection and disposal” of C&D waste in the Cape. However, the reuse of C&D wastes still remains a non-standardised practice for most contractors, even though the recycled aggregate industry has been under development in the Cape Peninsula since 2001.
Therefore, this characterisation study involves identifying C&D waste:
- Materials of value
- Material properties
- Material classification
- Potential applications
- Processing options
- Basic testing recommendations
- Material storage requirements
This has the potential to dispelling current negative perceptions and highlights the potential of C&D materials to be used on-site and be recycled in the Cape Peninsula.
