To analyse the potential for high-utility recycling, a literature study was conducted on the regulatory instruments, building standards, production and properties of recycled concrete aggregates and the recycled aggregate concrete for Sweden and European countries. Results urge statistics to quantify recycled concrete; regulations like source sorting of waste and selective demolition could potentially optimize recycled aggregate production. Also, the compressive strength of recycled concrete aggregate’s parent concrete influences the properties of the new concrete.
