A circular economy creates a policy conflict between increased resource circulation and decreased dispersal of hazardous substances. On the basis of three case studies in the EU, we have therefore identified various regulatory questions that can be posed to address the occurrence of hazardous substances in the use of waste. For each of these questions, we have proposed two possible responses influencing the design of the regulation and analyzed their consequences both from a circularity and from a toxicity perspective.

如何处理废物利用中资源循环与有害物质的政策冲突？

循环经济在增加资源循环和减少有害物质扩散之间产生了政策冲突。因此，基于欧盟的三个案例研究，我们确定了各种监管问题，以解决废物使用中有害物质的出现问题。对于这些问题中的每一个，我们都提出了影响法规设计的两种可能的反应，并从循环和毒性的角度分析了它们的后果。
