Onshore Wind Turbine Blade Recycling

What Happens to Old Wind Turbine Blades?

Last reviewed by Marcus Williams on 02 April 2026

Old wind turbine blades face a stark reality: landfilling, recycling, or repurposing. Landfilling remains the most common method due to its low cost and ease of implementation. However, environmental regulations are pushing for more sustainable options like recycling and repurposing.

Landfilling is the default disposal route for old Onshore Wind Turbine Blade Recycling due to its lower costs compared to recycling methods. However, growing regulatory pressure in Europe and North America is steering companies towards recycling or repurposing blades. Recyclers can break down blades into materials such as fiberglass composite, epoxy resin, balsa wood core, and carbon fiber for reuse. Repurposing involves transforming old blades into furniture, playground equipment, or bridges.

According to the World Economic Forum, e-waste is the fastest-growing waste stream globally.

How Are Wind Turbine Blades Recycled?

Recycling methods include cement kiln co-processing (GE/Veolia), pyrolysis for carbon fiber recovery, mechanical grinding into filler material, and repurposing into new products like bridges and playgrounds. Each method has unique benefits and challenges.

Cement kiln co-processing involves adding ground-up blades to the raw materials in a cement factory's kilns. GE Renewable Energy partnered with Veolia for this process, which recycles around 50% of blade material by weight. Pyrolysis separates carbon fiber from other materials through heat treatment without oxygen, retaining valuable fibers. Mechanical grinding turns leftover composite into filler for roads and construction. Repurposing involves creative applications like using blades as playground structures or sculptures.

What Does Wind Turbine Decommissioning Cost?

Decommissioning an onshore wind turbine costs between $30,000 to $150,000 per unit. This cost covers dismantling the turbine and disposing of its parts, including blades. The exact figure varies based on blade size and local regulations.

The decommissioning process involves significant labor and equipment expenses for safely removing large components like blades from wind farms. Larger turbines with longer blades typically incur higher costs due to increased material volume. Regulatory compliance also adds to the overall expense by requiring adherence to environmental standards during dismantling and disposal.

What Materials Are Recovered?

Fiberglass composite, epoxy resin, balsa wood core, and carbon fiber (in newer blades) are key materials recovered from wind turbine blade recycling. Each material offers unique recovery challenges and opportunities for reuse in other industries.

Fiberglass composites can be ground into filler or insulation material, while epoxy resins may find second life as adhesives. Balsa wood cores, though less common now, offer potential uses in construction or biodegradable packaging. Carbon fibers from newer blades are highly sought after due to their strength and lightweight properties. Suitable for aerospace and automotive applications.

According to the Apple Environmental Report 2024, apple recovered over 1 tonne of gold from recycled devices in 2023.

Regulations on Wind Turbine Waste

No federal mandate exists in the US regarding wind turbine blade recycling, but European Union countries are implementing landfill bans starting from 2025 (Germany, Netherlands, Finland). Some U.S. states like Iowa and Wyoming still allow landfilling despite increasing environmental concerns.

In Europe, stringent regulations aim to reduce waste and promote circular economy principles within the renewable energy sector. Meanwhile, in the United States, state-level initiatives have been more fragmented compared to federal policies seen elsewhere globally. For instance, Germany plans a complete phase-out of blade landfilling by 2025, while other regions follow suit.

The Wind Waste Problem

The future holds significant challenges for Onshore Wind Turbine Blade Recycling: projections indicate that global waste from decommissioned blades could reach 43 million tonnes by 2050 according to the University of Cambridge. In the U.S., over 8,000 blades will be decommissioned annually by 2025.

This growing pile of blade waste poses environmental and economic issues if not managed properly. Blade graveyards are becoming a visible problem in states like Wyoming and Texas. Where thousands of decommissioned turbines await disposal solutions. To address this looming crisis, innovative recycling technologies must scale up to handle the sheer volume expected over coming decades.
