Old wind farm blades present golden opportunity to UK supply chain

Old wind farm blades present golden opportunity to UK supply chain

At-scale recycling of wind turbine blades is an important first step towards achieving a zero carbon, zero-waste offshore wind industry and boosting the UK supply chain by 20,000 jobs

The Offshore Renewable Energy (ORE) Catapult is calling for increased investment and a radical shift in research and development into wind turbine blade recycling, citing the huge economic opportunities for the UK supply chain from a circular economy approach in offshore wind that could extend the sector’s UK job creation targets by 30 per cent, creating an extra 20,000 jobs.  

The Sustainable Decommissioning – Wind Turbine Blade Recyclingreport was produced under the Energy Transition Alliance (ETA), a partnership between ORE Catapult and OGTC, with input from experts at the National Composites Centre (NCC) and the University of Leeds. It was commissioned to investigate alternatives to landfill and incineration for end-of-life wind turbine blades.

Technically, wind turbines are almost 85-90% recyclable, but their blades, made from composites of resins and fibres, have proven challenging to break down, process and recycle, and remain the major hurdle to achieving fully recyclability. The report identified 14 technologies that show promise for recovering blade materials but that further work was needed before we see them deployed at scale, particularly around issues of environmental impacts, energy use and cost efficiency of techniques such as pyrolysis (heat treatment of composites).

This provides a golden opportunity for UK companies to provide solutions for our recycling needs. It is estimated that the global offshore wind industry will need to decommission 85GW of capacity (including 325,000 blades) by mid-century. While these estimates assume today’s 25-year lifecycle, they give an illustration of the scale of the future global market for circular economy pioneers in the sector.

Other key findings of the report include:

  • Recycling of all major components has the potential to generate an additional 5,000 UK offshore wind sector jobs. However, a more advanced circular economy model that brings in services such as remanufacturing and refurbishment of turbines and components would further extend this opportunity to 20,000 extra jobs, an increase of a third on the UK Government’s current 2030 targets.
  • To date, blade recycling efforts has been hampered by a failure to match recovered materials (resins and carbon/glass fibres) to supply chain needs and end-products. There is a need to focus efforts on creating a future supply chain for recyclates.
  • Cross-sector investment is crucial. The wind sector alone accounts for just nine per cent of the global composites market, with the remainder used by industries such as aerospace, automotive, oil and gas, defence and the leisure industries.

Chris Hill, Director of Operational Performance at ORE Catapult, said: “As the report makes clear, we are on the cusp of a break-through composites recycling solution. The technologies exist, but to be viable, they require intensified investment and some new approaches to studying and addressing the remaining innovation challenges. Engagement with the UK supply chain is the first step for us: recycling is only of benefit when the recovered materials have saleable end-products that prevent deployment of virgin materials.”

“Wind industry manufacturers and operators are beginning to set ambitious targets for achieving zero waste turbines within the next twenty years. There is also an active hotbed of research into lifetime extension of turbines, pushing towards 40-year lifetimes, as well as exploring alternative materials to composites. Recycling these first-generation blades is the first step in achieving zero waste, and as the report highlights, it can also be a stepping-stone to a spin-off circular economy.”

Dr Anne Velenturf, a Research Impact Fellow at the University of Leeds who is leading research on a circular economy for offshore wind with the ORE Catapult, added: “A high-value circular economy, in which wind turbines are designed for durability and for repair, reuse and remanufacturing ahead of recycling the materials, has a high potential to minimise carbon emissions and to open new business opportunities for companies in the UK, creating thousands of jobs in our communities.”

The next phase of the Energy Transition Alliance’s Blade Recycling Project will assess and appraise glass fibre recycling processes in order to identify the “best” potential solutions for further study and demonstration.  ORE Catapult has targeted an at-scale demonstration of blade recycling in the UK within the next five years through both the ETA Blade Recycling Project and a new joint industry project Circular Economy in the Wind Sector (CEWS).

ORE Catapult is keen to support offshore wind supply chain SMEs, manufacturers, owners and operators as they strive towards creating a circular economy for the wind sector. For more information, contact CIRCULAR@ore.catapult.org.uk.

Offshore Renewable Energy Catapult (ORE Catapult)

The Offshore Renewable Energy Catapult is the UK’s leading technology innovation and research centre for offshore renewable energy. We will play a key role in delivering the UK’s net zero targets by accelerating the creation and growth of UK companies in the offshore renewable energy sector. We will use our unique facilities and research and engineering capabilities to bring together industry and academia and drive innovation in renewable energy.



 Established in October 2016 with £180 million funding as part of the Aberdeen City Region Deal, OGTC is a not-for-profit, industry-led, technology research and development organisation based in Aberdeen. Please click here for a full background.

OGTC has already supported a host of companies focused reducing offshore carbon emissions, changing how they generate energy, preparing facilities to operate remotely and driving down the cost of hydrogen generation. 

The Centre is forging a cross-sector alliance with the Offshore Renewable Energy Catapult (ORE Catapult) to deliver an integrated energy vision for the North Sea that will collaborate across renewables, upstream and downstream oil and gas, energy suppliers, government and the Regulator.
