The urban mine is full of resources, but a circular economy is still too ambitious
Reuse everything and stop producing waste. By 2050, the Netherlands should have a circular economy. However, the new Integral Circular Economy Report by the Netherlands Environmental Assessment Agency (PBL) shows that there is still a long way to go. For the report, the Institute of Environmental Sciences…
