The hill above Douglas, Scotland had been spinning the same 26 turbines for close to thirty years.<\/p>\n
Then the cranes arrived.<\/p>\n
One by one, the blades came down, then the towers, then the gearboxes buried inside each nacelle.<\/p>\n
Nothing about the sight was unusual for a wind farm reaching the end of its life.<\/p>\n
What happened to the pile afterward was.<\/p>\n
A wind turbine is not one material, it is several stacked together, and that is what makes taking one apart<\/strong> harder than it looks. Steel towers and gearbox housings are straightforward, since scrap yards have handled structural steel for a century.<\/p>\n The problem has always been the blades, because their fiberglass shell is bonded with resin that will not simply melt back down or separate on its own.<\/p>\n At Hagshaw Hill, the blades went to Plaswire, a Northern Ireland processor whose line shreds, granulates and extrudes composite waste into a recycled material the company calls RX Polymer. That polymer does not become new blades. It goes into construction products<\/strong> that stand in for concrete, timber and virgin plastic, hardware that has to survive weather rather than spin for two decades.<\/p>\n Everything else followed more familiar paths, with steel towers, copper windings and gearbox parts going to scrap and component buyers<\/strong>. The operator says the majority of that supply chain sat within 30 miles of the site<\/strong>, and the short haul is a large part of why the recovery figure came out as high as it did.<\/p>\n Hagshaw Hill was not an ordinary machine to retire. Located in South Lanarkshire, it was Scotland’s first commercial wind farm<\/strong>, and for almost three decades its 26 turbines, each rated at a modest 600 kilowatts, were a fixture on the ridge near the village of Douglas.<\/p>\n So when the original machines finally reached retirement age, there was no local playbook for what to do with them.<\/p>\n Generating 15.6 megawatts combined, the site is described by its owner, ScottishPower Renewables, as the first onshore<\/strong> wind farm to be decommissioned in Scotland. That made the teardown a kind of working test case<\/strong>, with engineers figuring out, piece by piece, where an aging turbine’s materials could actually go.<\/p>\n The headline number came from a review after decommissioning by the consultancy Mott MacDonald, commissioned by the operator once the original turbines were dismantled in 2023. Near complete material recovery<\/strong> is what it recorded: 99.9 percent of the material accounted for, split between 79.5 percent sent for recycling and 20.4 percent reused or kept as spare parts, with a sliver left for landfill.<\/p>\n So almost nothing from the hill ended up buried.<\/p>\n The breakdown matters because it separates two different outcomes, material ground down and remade into something new, and whole components simply kept as spares or sold on for a second working life elsewhere.<\/p>\n The work also stayed inside the country. The review reported that all of the recycling<\/strong> and component retention took place within the UK, with contracts going to at least 10 supply chain companies<\/strong>. Ross Galbraith, onshore construction and operations director at ScottishPower Renewables, called the project “a real flagship project”<\/a> as it proves the company can commit wind power to being part of a circular economy.<\/p>\n Even a near perfect result like this one carries an asterisk, and it sits inside the blades. The review was commissioned by the site’s owner rather than by a regulator, and published figures for where shredded blade material finally lands are thin.<\/p>\n That gap does not erase the achievement, but it is a reminder that blade recycling is younger and less standardized<\/strong> than metal recycling. Industry estimates put the recyclable share of a whole turbine at roughly 85 to 95 percent<\/strong>, and most retired blades worldwide still go to landfill, which is what makes this outcome unusual rather than typical.<\/p>\n Elsewhere, wave energy researchers face a similar early stage challenge<\/strong>, testing how much power new machines can pull from the water, work being carried out on an indoor wave channel<\/a> in Oregon. Offshore, engineers are tackling the opposite end of a turbine’s life by building rotors that fold<\/a> upward for easier maintenance before they ever reach retirement.<\/p>\n Hagshaw Hill was small by modern standards, just 26 machines rated at 15.6 megawatts combined, less than a fifth of what the same ridge now carries. But its age made it an early test<\/strong> case for a wave of retirements still coming.<\/p>\n Thousands of first generation turbines<\/strong> across the US, UK and Europe were built in the 1990s and early 2000s and are now approaching the same milestone. If more of them can match even a fraction of what came off this one hillside, the scrap yards and composite processors absorbing old blades and steel could become one of the more overlooked chapters of the energy transition.<\/p>\n The hill near Douglas has already moved on. Where the old 26 once stood, 14 larger turbines<\/a> consented at up to 656 feet to blade tip now turn, lifting the site to more than 79 megawatts<\/strong>, roughly five times its original output.<\/p>\n","protected":false},"excerpt":{"rendered":" The hill above Douglas, Scotland had been spinning the same 26 turbines for close to thirty years.
