Circular Economy Systems
In a circular economy, growth comes from ‘within’, by increasing the value derived from existing economic structures, products and materials. Increased value in a circular economy derives from maintaining the integrity of a product at a higher level (technical and economic durability), using products longer (repeat use), cascading use in adjacent value chains and creating pure, high quality feedstock (avoiding contamination and toxicity). To drive value and support industrial take-up, circular economy business models and product flows need to be more cost effective, deliver superior revenues or improve capital and resource productivity to beat the linear model. Construction and buildings have the highest potential for circular economy innovation, value retention and creation opportunities.
In a circular construction economy, all EoSL buildings are material banks and deconstructable to retain high value materials and products and, given their bulk/value ratio, repair and remanufacture of products from EoSL buildings would be carried out and stored locally and then blended into new builds, also locally to minimise cost. All this will create value, promote innovation and attract investment.
To translate potential to reality requires a new circular building construction system that co-ordinates and integrates key players and activities including: building and product design, dismantling and separation, high value remanufacture and market place exchange. REBUILD brings together key players in building construction and ownership e.g. design, demolition, finance, maintenance, manufacture etc., at a regional scale to capture potential for circular economy innovation, value retention and creation opportunities.
