Abstract
The transition from a linear to a circular economy is a process that has already started throughout our societies as one important strategy to reduce CO2 emissions and by decoupling the use of natural resources, materials and fossil fuels from economic activity. Using examples from the Construction Industry, this paper argues that key premises must be present for circularity to happen. The business case at each level of the value circle must be viable. New building standards backed up by adequate policy measures, e.g. green public procurement, CO2 and virgin materials taxation is likely to be required. Finally, securing future supply of secondary raw materials (SRM) must be demonstrated and adequate supply chains of SRM to emerge.
