15. Remanufactured paint
Remanufactured paint costs roughly the same as ordinary paint of similar quality, but discounts could be available through participation in a paint recycling scheme.
In one case study (Debenhams) the estimated cost savings were around 22-24% which includes the purchase of paint and removal of unused paint.

21. "Buildings as material banks, energy generators and service providers… The future of architecture and construction will play a key role in the transition to a circular economy, and David Cheshire’s book makes a compelling case for a profound rethink."
The Ellen MacArthur Foundation
"I welcome the work David Cheshire has put into articulating a different future for an industry with so much potential for greater efficiencies."
