What is a wind turbine graveyard?

A wind turbine graveyard is a storage or landfill area designated specifically for retired wind farm parts. Most structures – foundations, towers, drivetrains and generators – are made from steel and copper that can be recycled or repurposed.

The most difficult components to handle are the blades. They are made from composite materials that resist breakdown and often end up buried or stockpiled, forming the so‑called wind turbine blade graveyard. This concentration of disused turbines serves as a stark reminder of the challenges of wind turbine blade disposal.

When turbines reach the end of their 20 to 25‑year lifespan, they are taken down and their components treated in various ways:

Foundational concrete is crushed for construction projects. Steel, copper, aluminium, and cast iron are recycled at rates of between 85 and 90 per cent.

Most are cut into pieces and sent to wind turbine landfills or storage yards. Some are incinerated for energy recovery or ground up and used as aggregate in concrete.

Innovative projects transform blades into benches, shelters, playground equipment or pedestrian and cycle bridges.

Despite recycling and reuse options, 100 per cent recovery is not yet viable.

The volume of wind turbine waste per year is growing rapidly. By around 2040, between 10 000 and 20 000 blades will be retired annually. In Europe, about 6 500 blades a year will be decommissioned by 2025. Global estimates predict up to 43 million metric tons of cumulative blade waste by 2050.

Yes, to a degree. While metal can be recycled, blade waste strains landfill capacity and can persist for centuries. Cutting blades into pieces consumes energy and increases material handling. Composite materials may leach substances or occupy large soil volumes.

Wind energy replaces carbon‑intensive fossil fuels and supports decarbonisation goals. It cuts far more CO₂ over its lifetime than disposal contributes, though end‑of‑life impacts are becoming significant when viewed at scale. Balancing climate gains with waste management remains essential for truly sustainable wind power.

Policies on wind turbine landfills are shifting to favour recycling and circular economy principles:

• Some countries, including Austria, Finland, Germany and the Netherlands, will ban blade landfilling by 2025.
• The EU’s circular economy and Green Deal encourage reuse, recycling and wind turbine disposal innovation.
• The International Energy Agency (IEA) and various governments are preparing guidelines for disposal practice.
• In the US, regulations vary by state, but some landfills now refuse to accept blade pieces.

The environmental trade‑off between renewable energy benefits and disposal impacts continues to drive industry innovation. As policy and technology evolve, more sustainable wind turbine disposal methods should emerge to close the loop on renewable energy systems.
