Intelligently recovering and recycling balsa wood
Intelligently recovering and recycling balsa woodThere are 30,000 wind turbines in operation in Germany, many of which are starting to age. In 2019, 2000 rotor blades had to be discarded; in 2024, this figure will shoot up to 15,000. But where to put these up to 90-meter-long, 15-metric-ton behemoths? Researchers from the Fraunhofer Institute for Wood Research, Wilhelm-Klauditz-Institut, WKI have a solution: they used a new recycling technique to recover and process the balsa wood contained in the rotor blades into, for instance, insulation mats for buildings.
