Legislation and standards are powerful levers to promote the recycling of products. In this WP, the various legislative tools and existing legislations framing the recycling of wind turbine blades will be reviewed as well as standards and certification schemes. The review will also look into sectors facing similar challenges and includelegislation for glass fibre composites in general. The WP will provide a preliminary review at the beginning of the task at M6 (Milestone 4.1), so that the other topical WP can analyze the influence of potential legislations and standards on the technical aspect of recycling as well as on the economic, environmental and social dimension ofrecycling. Towards the end of the task, WP4 will collect the knowledge and analysis performed in WP2 and WP3 in order to formulate the guidelines for the treatment of end of life wind turbine blades and how to best implement a recycling or other end-of-life solution.
