Roskilde Municipality is committed to implementing circular economy on an operational level. It sees circular economy as a holistic practice with roots firmly planted in the classical concept of sustainability - based on an environmental, social and economic perspective. Local recycling and reuse address the challenges related of the dwindling supply of raw materials for construction e.g. gravel. Local reuse has the added environmental benefit of reducing CO2 emissions and energy consumption, brought about by a reduction of transport of heavy materials to and from the building sites.
