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…

The city as an urban mine
Raw materials should no longer be excavated from mines, but reused from sources that are already present, such as unused underground electricity cables and discarded ships. At least, that is necessary for a circular economy. A new report explores where these resources are located and how we can use…
