Wind Turbine Recycling and Reuse

Detailed overview of innovation with sample startups and prominent university research

What it is

Wind turbine recycling and reuse involve managing wind turbine components that have reached the end of their operational life. This includes dismantling and recycling materials like steel, fiberglass, and composites, as well as repurposing or repowering turbine components for extended use.

Impact on climate action

Wind Turbine Recycling and Reuse within Wind Power reinforces climate action by minimizing waste and promoting circularity. By repurposing decommissioned turbine components and recycling materials, this innovation reduces environmental impact, conserves resources, and accelerates the transition to a sustainable energy system, mitigating climate change effects.

Underlying
Technology

Dismantling and Logistics: Wind turbines need to be safely and efficiently dismantled, and their components transported to recycling or repowering facilities.
Material Recycling: Various recycling technologies are used to recover valuable materials from wind turbine components, including:
- Steel Recycling: Steel from the tower and nacelle can be recycled using conventional steel recycling processes.
- Fiberglass and Composites Recycling: Recycling fiberglass and composites from wind turbine blades is more challenging, but several technologies are emerging, including mechanical recycling, chemical recycling, and pyrolysis.
Component Reuse and Repurposing: Some wind turbine components, such as gearboxes and generators, can be refurbished and reused in other turbines or for different applications.
Repowering: Repowering involves replacing older wind turbines with newer, more efficient models, often utilizing existing infrastructure like foundations and grid connections.
