If you want to get serious about creating circular materials response this Circular Economy framework by project stage is a good starting point. (The Framework is from “The Circular Economy in the Australian Built Environment: the State of Play and Research Agenda paper – from Deakin University).
Then, consider circular materials (in conjunction with low carbon) options at the following stages of construction.
- Plumbers – underground and above ground pipework – recycled PVC content, recycling PVC, PVC alternatives
- Concrete slabs and footings – recycled materials content and geopolymers
- Aggregates and sand – recycled aggregates and glass, alternatives
- Suspended concrete floors – simple thermal mass in domestic builds and low excavation impact
- Roofing – insulation integrity
- Timber framing and fixings – circularity
- SIPs – low carbon variants
- Bricks + blockwork – recycled and low carbon
- Insulation – recycled content
- Windows – recycled content and low carbon variants
- Electrical – recycling
- Plastering – recycling, installation, material alternatives
- Mechanical heating and cooling – technology choice and ductwork considerations
- Joinery – boards and fixings
- Carpet and carpet tiles – materials and installation
- Site management to support the above – Construction Waste Minimisation and Management Plans
If you want to fill in the gaps and find solutions within many of these categories we can help review your design and specification.
