‘Brief burst of intense heat’ could give hard-to-recycle wind turbine blades a second life

Summary

Researchers have developed a flash joule heating technique to convert decommissioned wind turbine blades into silicon carbide and graphene. By applying temperatures around 2,000°C for seconds, the process breaks down hard-to-recycle composite resins into materials that can strengthen new blades.

Key Takeaways

1. The study, published in the science journal Chem Circularity, found so-called ‘flash joule heating’ can transform blades – often made from silica-containing fiberglass and carbon-rich polymer resin – into silicon carbide and graphene, two valuable materials for manufacturing.
2. Annual decommissioned blade waste in Europe is projected to increase from 20,000 tonnes in 2025 to 55,000 tonnes by 2030 as older fleets reach their end-of-life.
3. WindEurope, the European wind industry association, introduced a voluntary industry-wide landfill ban that came into effect last year to tackle this.
