Wind turbines are excellent sources of clean, renewable energy. However, a problem comes up when these giant machines reach the end of their operational lifespan after 20 years of use. How should they be disposed of? Many of the parts can be recycled, but this can be a long process that takes a lot of energy. One European company has come up with a unique approach to recycling wind turbines. The main advantage of this method is that it does not require melting down large amounts of steel or other materials.
風力發電機是潔淨能源與再生能源的絕佳來源。然而，當這些巨型機械在運行二十年後達到使用期限時，一個問題隨之浮現。該如何處理它們？許多零件可以回收再利用，但這是一個漫長且極為耗能的過程。一間歐洲公司提出了一個回收風力發電機的獨特方法。此方式的主要優勢在於無須熔化大量鋼材或其他材料。
