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 2224% which includes the purchase of paint and removal of unused paint. Paint 360

"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 Mac. Arthur Foundation "I welcome the work David Cheshire has put into articulating a different future for an industry with so much potential for greater efficiencies.
