Ørsted commits to recycling of wind turbine blades

Offshore wind giant Ørsted commits to either reuse, recycle, or recover all of the wind turbine blades in its global portfolio of onshore and offshore wind farms upon decommissioning.

The commitment comes as a part of Ørsted's new company strategy which includes an ambition to expand its leading sustainability position and as part of the work towards achieving a carbon-neutral footprint by 2040.

"We want to help create a world that runs entirely on green energy, and we want to do it in a sustainable way. That includes moving towards more circular models where we reuse resources and save energy, thereby reducing carbon emissions. That is a big challenge, but we look forward to working on this challenge together with our supply chain,"
said Mads Nipper, CEO of Ørsted.

According to Ørsted, between 85 % and 95 % of a wind turbine can be recycled, but recycling of wind turbine blades remains a challenge, as the blades are designed to be lightweight, yet durable, making them challenging to break apart. Consequently, most decommissioned blades are landfilled today. Should the challenge with recycling blades take longer to solve than anticipated, Ørsted will not use landfilling for decommissioned wind turbine blades, but will instead temporarily store the blades.

Up until now, Ørsted has only decommissioned the offshore wind farm Vindeby in Denmark where the blades from the 11 wind turbines were all reused.

"Already today, power produced from offshore wind has 99 % lower life cycle emissions than coal-fired power. Our ambition is to offer our customers carbon-neutral renewable energy solutions with responsible use of resources, seen from a life cycle perspective. This requires decarbonising our supply chain, and it involves moving to more circular models of resource use in the wind turbine supply chain,"
added Mads Nipper.

"I hope that our commitment will inspire others which will help to bring scale to the market for recycling solutions of wind turbine blades, thereby accelerating the cost-out journey of the alternatives to landfilling, and help boost the already ongoing innovation in the wind energy supply chain on how to design to avoid waste."

Ørsted is already contributing to advancing the technologies that can recycle wind turbine blades in a sustainable way as a founding partner of the cross-sector DecomBlades consortium consisting of wind industry companies and research institutions. The consortium seeks to investigate and develop solutions to recycle the composite material in wind turbine blades. The consortium recently received a three-year funding from Innovation Fund Denmark for its work.

"No one has all the solutions to how to move towards more circular models. We need collaboration across companies and research institutions to find the answers which the DecomBlades project is an important example of,"
concluded Mads Nipper.
