**3.4 Policies**

The circular design becomes interesting only when the plus value is measured and recognized. Public policy can contribute by acting as an initial customer and guiding the development of measurement methods and chain knowledge. In addition, there is room for experimentation with rules, so that companies can experiment with new construction methods and cost-effective projects. In addition, the benefits of ring design will only be felt in the long run. Thus, the government is primarily the country that can give meaning to the development of circular constructions.
