How Sweden Recycled Old Wind Turbine Blades Into Parking Garage Architecture

What is the Niels Bohr car park in Lund?

In southern Sweden, the city of Lund has opened the Niels Bohr car park, a multi-storey facility whose façade is built from 57 retired wind turbine blades donated by the energy company Vattenfall. The car park stands in the fast-growing Brunnshög district and is described as the first in Europe to integrate decommissioned rotor blades as prominent exterior elements. (Interesting Engineering)

Named after the Danish Nobel Prize-winning physicist Niels Bohr, the building provides both short- and long-term parking for residents and visitors, linking scientific heritage with a visible symbol of circular design in a high-tech neighborhood. It is owned and operated by Lunds kommunala parkeringsbolag (LKP), the municipal parking company, which manages roughly 28,000 parking spaces across Lund. (LKPAB)

How are old wind turbine blades used in the structure?

The 57 blades, originally installed at Vattenfall’s now-decommissioned Nørre Økse Sø wind farm in Denmark, were carefully cut and mounted into “curtain walls” — non-load-bearing façade panels that visually wrap large parts of the exterior. Many were arranged in sweeping V-patterns, and circular portholes cut into the blades let daylight wash across the interior in a rhythmic pattern. These elements give a new purpose to composite components that are normally difficult to recycle and often end up in landfills. (Vattenfall)

Architect Jonas Lloyd of Lloyd’s Arkitektkontor developed the idea after reading a magazine article about blade-disposal problems in the U.S. wind sector and wondering whether the material could be given a more productive second life. “I read that in the U.S., many of the blades are buried, and I thought they could be put to better use. It’s not just an environmental problem, but also a waste,” he said, describing the project as “an eye-opener” meant to show that discarded blades can become architectural features rather than buried debris.

What does the building offer drivers and the neighborhood?

The car park rises five floors (described locally as 13 half-levels) and offers up to 365 parking spaces, a figure LKP put closer to 265 in its pre-opening communications, depending on how the spaces are counted. It includes 40 charging points for electric vehicles, reflecting the district’s push toward low-emission transport. (Energy-Pedia)

Solar panels on the roof feed power to the building and its charging stations, and an on-site battery stores surplus energy so that no locally generated electricity is wasted, including for charging cars at night. The façade pairs the white blades with large planters of pollinator-friendly vegetation, adding a biodiversity element to what might otherwise be a conventional concrete structure. (LKPAB)

Why are wind turbine blades so hard to deal with?

Rotor blades are made from tough composite materials such as glass-fiber and carbon-fiber reinforced plastics, designed to endure decades of mechanical stress, UV radiation, and harsh weather. That durability makes them difficult to break down, which is why, in many regions, blades removed from service are cut up and landfilled or incinerated. (Interesting Engineering)

As wind farms built in the early 2000s reach the end of their service lives, the volume of retired blades has become a growing waste challenge worldwide. The U.S. Department of Energy has reported that about 90% of a turbine’s material mass can already be recycled with existing infrastructure, leaving the remaining roughly 10% — blades chief among it — as the stubborn part of the problem. Projects like the Lund car park respond to that pressure by finding alternate uses for existing blades while recycling technologies and regulations continue to evolve. (Vattenfall)

What do Vattenfall and LKP say about the project?

Anne Mette Traberg, Vattenfall’s country manager for Denmark, called the Lund facility “visible and concrete proof that sustainability can meet the cost, schedule and safety requirements of a project,” framing it as evidence that circular solutions in wind power can move beyond pilot scale. With more than 1,400 turbines across several countries, Vattenfall has pledged to reuse, refurbish, repurpose, or recycle 100% of its blades, nose cones, and nacelle covers by 2030, has banned sending blades to landfill, and has already turned old blade material into solar-panel frames, insulation, and even skis — alongside an earlier project that converted a turbine nacelle into a tiny house. (Vattenfall)

LKP CEO Paul Myllenberg acknowledged that the idea of cladding a car park in old blades initially raised eyebrows, but said “reality exceeded expectations” and praised the board for backing a concept that turns a difficult waste stream into a visible statement on resource efficiency. With several of the 57 donated blades still lacking a clear use, LKP launched a public competition inviting people to submit ideas for how the remaining blades could be put to work, offering a month of free parking to the winner. (LKPAB)

Is this part of a wider trend in reusing turbine components?

Vattenfall describes the Niels Bohr car park as part of a broader shift “from blades to buildings,” in which components from decommissioned turbines are turned into infrastructure and design objects instead of waste. The company has highlighted other projects where blades and towers are repurposed into compact housing or structural elements, feeding into its wider circular-economy goals for offshore and onshore wind assets. (Vattenfall)

Industry observers note that the Lund project is drawing interest from architects and city planners weighing how large composite parts such as blades might serve as ready-made beams, shells, canopies, walkways, or façade pieces in future developments — an especially promising option for municipalities near aging wind farms. Some also caution that long-term weather exposure, maintenance, and cost will determine how widely the approach can be replicated. If similar schemes spread, wind farms could see their components designed with “second lives” in mind from the start, easing future decommissioning and reducing material waste.
