never to fail.<\/p>\n<p>Twenty five years of gusts, ice, heat and load reversal, bending millions of times over without a crack opening anywhere along it.<\/p>\n<p>The industry met that specification.<\/p>\n<p>Then the blade comes down, and the same property becomes the whole problem, because nothing at a waste site can process an object engineered&nbsp;<strong>never to break<\/strong>.<\/p>\n<p>So it goes in the ground.<\/p>\n<p>More than a thousand&nbsp;<strong>turbine blades<\/strong>&nbsp;lie in&nbsp;<strong>one landfill cell<\/strong>&nbsp;on the high plains, and being careless had nothing to do with it.<\/p>\n<h2>The chemistry that will not run backward<\/h2>\n<p>A blade is glass fiber locked into cured epoxy.<\/p>\n<p>Cured is the operative word, because a thermoplastic melts and can be shaped again while a thermoset sets once and sets permanently.<\/p>\n<p>Heat does not soften it.<\/p>\n<p>Heat destroys it, so there is&nbsp;<strong>nothing to melt<\/strong>&nbsp;and nothing to separate either, because the glass and the resin have become a single object.<\/p>\n<p>Landfill machinery works by crushing.<\/p>\n<p>That is precisely what a blade was designed to resist, and a dozer can climb over a section and&nbsp;<strong>the section survives<\/strong>.<\/p>\n<p>Burning one whole is not an option either.<\/p>\n<p>A blade fed straight into a furnace leaves a mass of glass ash that fouls the equipment, which is why the material has to be reduced first.<\/p>\n<p>Which leaves cutting.<\/p>\n<p>Cutting composite means a diamond wire saw working at the turbine before anything moves at all, and that is&nbsp;<strong>expensive per foot<\/strong>.<\/p>\n<h2>What actually went into the trench<\/h2>\n<p>The blades came off four wind farms.<\/p>\n<p>Sites around Glenrock, Arlington, Saratoga and Hanna sent them to the regional landfill outside Casper.<\/p>\n<p>Each one arrived in three pieces.<\/p>\n<p>A blade of roughly&nbsp;<strong>120 feet<\/strong>&nbsp;left its tower as three sections of about 40 feet, because that is what fits on a semitrailer.<\/p>\n<p>In the cell they were nested.<\/p>\n<p>The narrow tip section was pushed inside the wide root section like a stack of cups, which is the only reason the volume stayed manageable.<\/p>\n<p>Even nested it swallows space.<\/p>\n<p>One blade occupies about&nbsp;<strong>44 cubic<\/strong>&nbsp;yards, the load of three concrete mixer trucks, and the city was paid&nbsp;<strong>$602,000 in all<\/strong>&nbsp;for the room.<\/p>\n<h2>What the dates actually show<\/h2>\n<p>Deliveries began in May of 2019.<\/p>\n<p>The count reached&nbsp;<strong>1,124 blades<\/strong>&nbsp;by the middle of September the following year, which is the figure that has been circulating ever since.<\/p>\n<p>Then it simply stopped.<\/p>\n<p>No wind farm has taken a blade to that site since the middle of 2021, and the landfill manager says operators stopped calling.<\/p>\n<p>Nothing was outlawed.<\/p>\n<p>Sites that still accept composite want it ground to chunks&nbsp;<strong>four inches<\/strong>&nbsp;or smaller first, and grinding at that scale costs more than operators are willing to pay.<\/p>\n<p>The four inch rule is the real gatekeeper.<\/p>\n<p>Reducing a 120 foot blade to fragments that small takes an industrial shredder and a haul to wherever that shredder happens to sit.<\/p>\n<p>Burial did not become illegal.<\/p>\n<p>It became&nbsp;<strong>the expensive option<\/strong>, which is a far duller explanation than the aerial photographs of that trench usually carry.<\/p>\n<h2>The word recycling is doing a lot of work<\/h2>\n<p>What replaced burial sits on a river.<\/p>\n<p>A plant in a Missouri river town has been shredding blades since 2020 and has passed&nbsp;<strong>7,000 of them<\/strong>, turning out something like coarse sawdust.<\/p>\n<p>The powder goes into cement kilns.<\/p>\n<p>By&nbsp;<a href=\"https:\/\/www.veolianorthamerica.com\/what-we-do\/waste-capabilities\/wind-blade-recycling-program\" target=\"_blank\" rel=\"noopener\">the operator<\/a>&#8216;s own accounting each blade displaces five tons of coal, 2.7 tons of silica and 1.9 tons of limestone.<\/p>\n<p>The fiberglass is consumed.<\/p>\n<p>Nothing comes back out as fiber and no second blade is ever built from the first, which puts it nearer to what happens to&nbsp;<a href=\"https:\/\/www.ecoportal.net\/uk\/solarcycle-opens-solar-panel-recycling-plant\/2100\/\">recycled panels<\/a>&nbsp;than to&nbsp;<strong>a returned bottle<\/strong>.<\/p>\n<p>Geography decides the rest.<\/p>\n<p>A blade is a low value and enormously bulky object, so hauling one several hundred miles to a kiln can cost more than&nbsp;<strong>the material earns<\/strong>&nbsp;at the far end.<\/p>\n<h2>The decision was made at the factory<\/h2>\n<p>Scale is the harder half.<\/p>\n<p>Estimates put the global blade waste stream near&nbsp;<strong>47 million<\/strong>&nbsp;tons by the middle of the century, and the list of kilns able to take it is finite.<\/p>\n<p>The clever answers stay small.<\/p>\n<p>Two blades became&nbsp;<a href=\"https:\/\/www.ecoportal.net\/uk\/a-county-londonderry-footbridge-built-from-two-retired-turbine-blades\/2169\/\">a footbridge<\/a>&nbsp;in Ireland, which is a genuinely good idea and is also two blades.<\/p>\n<p>Every option here was priced decades ago.<\/p>\n<p>Somebody specified a thermoset resin, which was the right call for the blade and was never a decision about the blade&#8217;s last day.<\/p>\n<p>Newer resins are meant to come apart.<\/p>\n<p>A mild solution releases the glass fiber intact and the resin as a reusable liquid, which turns disposal into&nbsp;<strong>a chemistry question<\/strong>&nbsp;instead of a hauling one.<\/p>\n<p>Those blades are still up there.<\/p>\n<p>They will not come down for another twenty years or so, which leaves everything already on the ground needing somewhere to go, as&nbsp;<a href=\"https:\/\/cowboystatedaily.com\/2024\/08\/21\/why-old-wind-turbine-blades-arent-being-buried-in-landfills-anymore\/\"
