This research discussed circularity and gave a proper definition for this for the Dutch water boards. This research developed an implementation tool that can be used by the water boards. It shows which design criteria exist within the core measurement method of cb23. These design criteria consist of 7 indicators. It is advised to use these indicators as circular ambitions for the water boards. These indicators can be measured over time, in which the water boards can effectively steer and measure these ambitions. This research showed 42 circular strategies, which have been connected to the ambitions of the CMM through an implementation tool. Strategies are connected to one of the 9 life cycle stages of an asset. These strategies, however, can conflict which each other. For example, solar panels might generate green energy, but if the alloys used can not be recovered, this results in a valuable loss of scarce materials. Moreover, some strategies are dependent on other strategies or can create synergy. An overview of these interactions is provided.
