How can we reduce our construction waste?
- Reduce. The first step in cutting the amount that ends up in landfill is to reduce the quantity that is produced in the first place.
- Reuse. Any surplus items or material salvaged from demolition needs to be stored properly, in a secure, weatherproof area.
- Recycle.
