This research is focused on the analysis of the alternatives to recover wind turbines at the end of their useful life after several years of operation: a) Dismantling for recycling or disposal; b) Lifetime extension or revamping, after a high investment in maintenance to keep the wind turbine under operation and control; or c) Remanufacturing combined with repowering in order to reuse, remanufacture, recycle or disposal of the different components according to their condition and the most convenient recovery option from an economic and environmental point of view. In addition, the design of a closed-loop supply chain and an effective reverse logistic network are considered to maximise the benefits of remanufacturing.
With the current wind farms, 80% to 90% of the wind turbines can be recycled. Apart from cost reduction, sustainability including material circularity is an increasingly important driver and challenge to the wind industry. To realize the circular wind turbine, the design philosophy must be adapted to the circular economy thinking. Today's thermoset composite wind turbine blades are very difficult to recycle. TNO has analysed various circular solutions for a wind turbine blade based on both the business case and the Life Cycle Assessment (LCA).
The presentation will focus on the lifecycle of a wind turbine and the opportunities it presents to the application of circular economy technology. It will be an exposition of the present status for refurbishment and remanufacture within the sector, and the work we are doing to change a predominantly linear culture of procure only new, to one where owner operators seek a reuse as a preference. Fundamentally it will be about how we make the Aftermarket more sustainable while improving cost and performance.

Rachel Waugh, European Remanufacturing Council
Rachel Waugh has been working on remanufacturing for nearly 8 years as part of her role as Senior Consultant at Oakdene Hollins, a Circular Economy consultancy based in Buckinghamshire, UK. She joined Oakdene Hollins after completing her PhD in Engineering at the University of Cambridge as part of the WellMet2050 project, which aimed to explore all credible means for reducing the global CO2 emissions of the steel and aluminium industries and was her introduction to remanufacturing. She has been involved in a broad range of remanufacturing projects, including remanufacturing markets studies for Malaysia, Scotland, Canada and Europe. In 2014, she co-ordinated the successful Horizon2020 bid to run the European Remanufacturing Network, out of which the European Remanufacturing Council was established in 2017. She is married to a real life rocket scientist and her free time is currently spent homeschooling her two young children!
Harald van der Mijle Meijer, TNO
Harald is senior consultant wind energy at the Dutch research organization TNO and has more than 15 years of experience in wind energy research and development projects at an international level. With his passion for the wind and the sea and background in materials science, his focus is on sustainability and circularity of offshore wind turbines. Within TNO he is responsible for the research and market combination cluster circular wind farms with a focus on wind turbine design for circularity and recycling of wind turbine blades.
He has worked for various companies and the Royal Netherlands Navy in the field of material application and maintenance in aerospace and marine applications and corrosion protection of wind turbine support structures.
In his spare time he uses the wind as a sailor and with kitesurfing.
