A Recycling Plan to Clear Wind Turbine Blades From Graveyards

It’s difficult to recycle a gigantic wind turbine. The blades are built to withstand extreme weather, from scorching desert heat to hurricane-like winds, and that means their life almost always ends in a landfill. In Europe alone, about 3,800 blades will be removed every year through at least 2022, according to BloombergNEF, as the oldest turbines reach retirement age.  Now a Danish startup has found a way to crush these blades, turning an ultra-resistant mix of fiberglass and industrial glue into barriers designed to block noise from highways and factories. Copenhagen-based Miljoskarm can grind the blades into small pieces of 1 to 2 centimeters with the same type of machines used in auto junkyards. The material is then placed in recycled plastic cases that block noise at least at the same level as barriers made from aluminum and mineral wool, with less maintenance required. - Bloomberg Green
