Wind turbine blade recycling: turning waste into value

Page date: Published 10 Jul 2025; updated 30 Sep 2026. 3 min read.

The article says turbine blades are generally fibre-reinforced polymer composites, typically glass fibre in resin, with some carbon fibre in higher-performance blades. It states blades may be retired after 20–25 years and that many currently go to landfill because the materials are difficult to separate; some are incinerated or used for energy. It describes dismantling and transport as costly and labour-intensive, often requiring cranes, trained crews, cutting equipment and special transport permits.

Recycling methods discussed include pyrolysis, which heats blades without oxygen to remove resin and recover fibres with reduced strength; solvolysis, which dissolves resin and remains at pilot stage; mechanical shredding for concrete panels or fillers; and reuse in benches, footbridges or bicycle shelters. The article says metal and concrete make up most readily recyclable turbine material, while composite-blade recovery remains partial. It also cites DecomBlades’ work using reclaimed fibre in new blades.

The page frames landfill avoidance, reduced use of virgin materials and circular-economy policy as motivations. It refers to European countries banning blade landfill by 2025; this is a past deadline cited without an implementation update and should be checked before relying on it as current regulation. It notes research into designing future blades for easier disassembly or recycling. Related links: Energy; Offshore wind; turbine lifespan; drone inspection; REWIND; DecomBlades.
