Wind turbines typically have a lifespan of 25–30 years. After this period, they may be decommissioned, repowered (replaced with newer, more efficient turbines), or upgraded. However, decommissioning can bring its own environmental challenges, particularly when it comes to dealing with large components.
Blades, towers, and nacelles (the casing that holds the turbine’s generator) can be difficult to dismantle and recycle due to their size and the mix of materials used. Steel, iron, aluminium and copper components are readily recyclable but fibreglass or composite materials are more difficult.
Currently research is underway in Ireland that is exploring methods to recycle or reuse the fiberglass and composite materials in turbine blades. Companies and research institutions, such as those collaborating through the Re-Wind project (a partnership involving researchers from Ireland, the US, and Northern Ireland), are leading efforts to give turbine blades a second life.
The Re-Wind project, in particular, is testing innovative repurposing methods, such as turning old blades into pedestrian bridges, skate parks, road barriers, and even public art installations. This approach not only avoids landfill waste but adds social value by integrating these structures into communities.
Blade Bridge along with university support has already commissioned several projects across Ireland.
Midleton to Youghal Greenway bridge
Two LM13 blades from Northern Ireland were utilised in place of the superstructure’s steel girders.
Achill Sound Greenway Furniture
The main piece is a bench with integrated bike parking. The second is a seat with a standing table combination. Both are finished with the sustainable and long-lasting Accoya wood, and are positioned with a stunning view of Achill Bay. The third piece is a picnic table, also finished with Accoya wood, and positioned at the end of the greenway.
