Wind turbine blades to be 100% recyclable by 2024, says Vestas

A new technology enabling total circularity for wind turbine blades has been developed by industry and academic leaders, reports wind turbine manufacturer Vestas.

Wind turbines are already 85–90% recyclable. Now, a new solution developed by the Circular Economy for Thermosets Epoxy Composites (CETEC) initiative proposes the recycling of epoxy resins, the highly stable polymer chains used in turbine blades.

Wind Power Market seeing increased risk and disruption

The wind power market has grown at a CAGR of 14% between 2010 and 2021 to reach 830 GW by end of 2021. This has largely been possible due to favourable government policies that have provided incentives to the sector. This has led to an increase in the share of wind in the capacity mix, going from a miniscule 4% in 2010 to 10% in 2021. This is further set to rise to 15% by 2030. However, the recent commodity price increase has hit the sector hard, increasing risks for wind turbine manufacturers and project developers, and the Russia-Ukraine crisis has caused further price increase and supply chain disruption. In light of this, GlobalData has identified which countries are expected to add the majority of wind power capacity out to 2030.

The initiative, which includes Vestas, epoxy producer Olin, Aarhaus University and the Danish Technological Institute – and is partly funded by Innovation Fund Denmark – hopes to present a solution ready for industrial adoption within three years.

The development of CETEC’s technology, which involves disassembling the blade's composite material at end-of-life, is a “game changer”, says Simon Frølich from the Danish Technological Institute.

The technology consists of two stages. Thermoset composites are disassembled into fibre and epoxy before the epoxy is further broken up into base components through a novel chemical recycling process. These materials can then be used to manufacture new turbine blades.

When fully developed, the solution may also have an impact on other industries that rely on thermoset composites in production, such as the automotive and aviation sectors.
