风机叶片不再填埋，丹麦如何把退役巨刃变成资源？
A growing mountain of waste lurks behind the clean energy success of wind power. Modern turbine blades, longer than a football field, are built from tough composite materials that can last for decades. But when they reach the end of their service life, burying them in landfills has become an increasingly unsustainable habit. In Denmark, a country that leans heavily on wind, this problem has sparked a quiet engineering revolution.
At an industrial park near Esbjerg, a facility run by the start-up ReBlade Solutions has set out to prove that a blade’s final spin does not have to end in a hole in the ground. Workers guide the enormous structures into a custom-built saw, which cuts them into smaller segments. These chunks then enter a sealed pyrolysis chamber, where intense heat in the absence of oxygen breaks down the resin without burning the fibers. The process strips away the sticky polymer, leaving behind clean, reusable glass fibers.
