How Scotland’s First Commercial Wind Farm Achieved Near-Zero Waste
Glasgow, Tuesday, 8 September 2026.
Scotland’s first commercial wind farm achieved an unprecedented 99.9% recycling and reuse rate during decommissioning, successfully repurposing even the historically difficult turbine blades into construction polymers.
A Landmark Decommissioning in South Lanarkshire
Hagshaw Hill, Scotland’s first commercial onshore wind farm, began operating in 1995 with 26 turbines of 600 kilowatts (kW) each, totaling 15.6 megawatts (MW) of capacity [1][2]. Located in South Lanarkshire, the wind farm was dismantled in 2023 after nearly 30 years of operation [2]. A recent decommissioning report compiled by Mott MacDonald for ScottishPower Renewables, published around September 6, 2026, confirmed that an unprecedented 99.9% of the materials from the original 26 turbines were successfully recycled or reused [1][2]. This milestone provides a real-world case study for circularity in wind energy, which is particularly relevant as the UK’s Onshore Wind Taskforce projects decommissioning to peak between the late 2020s and 2030s at 0.5 GW to 1 GW annually [2].
Overcoming the Turbine Blade Recycling Challenge
Historically, wind turbine blades have represented the most difficult component to recycle, often ending up in landfills due to their robust composite structures [3][GPT]. However, for the Hagshaw Hill project, ScottishPower Renewables partnered with Plaswire, a recycling specialist based in Lurgan, Northern Ireland [2][3]. Plaswire successfully processed all the decommissioned turbine blades, transforming them into a specialized polymer known as “RX Polymer” [2]. This proprietary polymer is used to manufacture construction and engineering products, such as site fencing, marker posts, and drainage components, substituting traditional materials like concrete, timber, and virgin plastics [1][2].
Local Economic Impact and the Repowering Process
Led by Chief Executive Andrew Billingsley, Plaswire experienced a 50% increase in output in 2026 following a 30% growth in 2025, and the company plans to double its workforce over the next 12 months while preparing to open a second facility in Scotland [2][3]. The decommissioning and repowering program at Hagshaw Hill supported over 100 jobs and secured contracts for at least 10 UK-based companies [2], with the majority of the supply chain contracts sourced within 30 miles (48.28 kilometers) of the site [1]. Ross Galbraith, the onshore construction and operations director for ScottishPower Renewables, emphasized that the project demonstrates how wind power can support a circular economy and foster a new industry for the future [1].
Methodological Considerations and Future Outlook
Following the decommissioning of the 1995 assets, the site was “repowered” in 2025 [1]. The original 26 turbines, which had a combined capacity of 15.6 MW, were replaced by 14 larger, more efficient turbines with a total capacity exceeding 79 MW (commonly cited as 80 MW) [2][4]. This represents a significant capacity increase of 64.4 MW, allowing the repowered facility to generate enough clean electricity to power the equivalent of approximately 57,000 homes annually [4]. While the 99.9% recycling and reuse rate sets a high benchmark, analysts note that the definition of recycling boundaries heavily influences these figures, as concrete remains the dominant material when foundations are included in the calculations [2]. Nonetheless, with ScottishPower planning to decommission approximately 1 GW of its own portfolio over the next decade [2], this circular approach will be vital to sustaining the green energy transition.
