From tiny houses to skis: This Swedish company is finding creative uses for retired wind turbines
Europe’s wind expansion brings a new challenge: what happens when turbines retire?
Poinews.com – Europe is heading towards a record year for new wind power, with 8.8 GW of capacity added during the first six months of 2026. That represents a 30 per cent increase from the same period a year earlier. The new installations could supply electricity for roughly seven million households across Europe while avoiding fossil-fuel imports comparable to 25 liquefied natural gas tankers annually, WindEurope has said.
The rapid build-out is a major step for clean energy, but it also highlights an issue that will become increasingly important as older projects reach the end of their working lives. Wind turbines are built to withstand severe weather for as long as 25 years. Eventually, however, they must be dismantled, refurbished or replaced.
Most of a turbine is not especially difficult to recover. Steel, copper, aluminium and concrete account for as much as 90 per cent of its total mass and can generally enter established recycling streams. The tougher question concerns the giant blades and certain outer components, which are made from complex layered composites.
Why turbine blades are difficult to recycle
A blade may stretch from 50 to 100 metres. Its strength comes from combining materials including glass fibre, carbon fibre, epoxy resin, balsa wood, metals and fillers. Those materials are tightly fused together, creating a durable structure capable of turning for decades in demanding conditions.
That same resilience makes separation difficult once a blade is decommissioned. Recovering the component materials requires specialised treatment, sometimes involving high temperatures or other energy-intensive processes. Even when materials are recovered, the process may reduce their quality or commercial value, limiting the appeal of recycling at industrial scale.
“Separating the composite materials from the resin requires specialised processes, often involving high temperatures or other energy-intensive treatment methods,” Eva Julius-Philipp, Director of Environment and Sustainability of Business Area Wind at Vattenfall, says. “In some cases, these processes can affect the quality and value of the recovered materials, making large-scale recycling more challenging.”
Vattenfall introduced a ban on sending blades, nacelle covers and nose cones to landfill in 2021. Since then, the company has explored ways to keep retired turbine parts in use before resorting to more energy-intensive treatment.
A nacelle cover becomes a compact home
One striking example began with a retired nacelle cover from an Austrian wind turbine. The nacelle is the housing positioned at the top of a tower, protecting much of the turbine’s electrical and mechanical equipment. Its cover was repurposed with design studio Superuse as a small living unit.
The former turbine component measures four metres wide, 10 metres long and three metres high. It has been redesigned to include a kitchen, bathroom and living area, alongside a heat pump, solar panels and a solar water heater. The project was displayed during Dutch Design Week in 2024.
The purpose was not simply to create an unusual tiny house. It was an experiment in retaining the value already embedded in a large industrial component, rather than breaking it down through high-emissions processing. In circular design terms, direct reuse can preserve more material and require less energy than turning a product back into raw inputs.
From blades to buildings and skis
Retired blades are also finding roles beyond the wind sector. The 57 blades removed from Denmark’s Nørre Økse Sø onshore wind farm after its 2023 decommissioning were incorporated into the facade of a multi-storey car park in Lund. Their size, lightweight strength and distinctive shape make them potentially useful as structural or architectural elements.
Other ideas being tested include supports for solar-panel installations and alpine skis made using recycled blade material. These applications are still limited in scale, but they demonstrate how a component once treated largely as a disposal problem can become a resource for other industries.
“Projects such as the Tiny House, blade-based building projects and recycled skis are not yet a large-scale solution, however they are intended to help us gain experience, develop new applications and stimulate the market for circular solutions,” Julius-Philipp says.
Where safety permits, reuse or refurbishment is the preferred route because it extends the useful life of existing components. If high-value recycling is not viable, composite materials can also be directed to energy recovery or cement co-processing. Vattenfall is using mechanical techniques that turn blade material into composite flakes or fillers for new products, while pyrolysis, a thermal process, can recover fibres and other secondary materials.
Scaling the circular wind economy
Technology is only one part of the equation. Retired blades do not arrive in steady, predictable quantities, which makes it more difficult for specialist recycling businesses to invest and operate economically. That pattern is likely to change as the earliest large European wind farms approach the end of their operational lives and more equipment enters retirement.
The next phase will require solutions that can process materials at sufficient volume while remaining cost-effective and energy-efficient. It will also depend on markets willing to use recovered composites in new products and construction projects.
At EU level, landfill restrictions for decommissioned blades are not yet mandatory across all member states. Austria, Finland, Germany and the Netherlands have binding national bans. WindEurope is seeking an EU-wide legal commitment, arguing that consistent rules would help create the conditions for circular supply chains and secondary-material markets to grow.
For wind energy, the task is becoming clearer: producing low-carbon electricity is only part of the lifecycle story. Designing practical routes for turbine components after retirement will determine how fully the sector can deliver on its broader circular ambitions.
