Lab study tests heat treatment for recovering glass fibre from old blades
Source: Polymer Composites, "Thermal Conversion Properties of Glass Fiber Reinforced Polymer in End‐of‐Life Wind Turbine Blades", published 10 November 2026.
What the source says
Laboratory thermochemical tests on GFRP from end-of-life wind turbine blades compared N2 and CO2 atmospheres and heating rate. Volatiles were released mainly between 300°C and 430°C. Oxidation at 500°C for 30 minutes cleared char; pyrolysis at 800°C left the least char but more fibre defects.
Allbase view
Lab-scale thermal tests on blade waste, not a working recycling process. Hotter pyrolysis leaves cleaner glass fibre but more damage, so recycled fibre for structural laminates remains some way off; nothing to act on yet.
