Over het archief
Het OWA, het open archief van het Waterbouwkundig Laboratorium heeft tot doel alle vrij toegankelijke onderzoeksresultaten van dit instituut in digitale vorm aan te bieden. Op die manier wil het de zichtbaarheid, verspreiding en gebruik van deze onderzoeksresultaten, alsook de wetenschappelijke communicatie maximaal bevorderen.
Dit archief wordt uitgebouwd en beheerd volgens de principes van de Open Access Movement, en het daaruit ontstane Open Archives Initiative.

| Abstract |
Early offshore wind farms approach their decommissioning phase, yet a lack of precedents, potential legal bottlenecks, inadequate treatments and a lack of applicable circularity indicators, leave the sector unprepared, encompassing a risk of valuable materials loss. This paper presents a first-of-its-kind circularity analysis of the prospective decommissioning scenario of a North Sea wind farm, introducing and applying new circularity indicators. From the site-specific primary data, a bill of materials and material flow analysis was established, differentiating between secondary applications and end-of-life destinations. The main share (80 %) of the installed mass originated from scour protection, acting as hotspot to the 84 % of materials remaining in situ. The collected fraction recycling rate approaches 90 %. However, the substantial discrepancies between components and materials implicate a need for component or material-specific targets to avoid valuable material loss. Introducing such collection or recycling targets could encourage more circular decommissioning practices along the value chain. |
