You notice that the dryer ate one of your socks, so you wonder to yourself, are single socks recyclable? The answer may surprise you: yes. Even though they seem unsellable at charity stores like Goodwill, the nonprofit will gladly take your single socks off your hands. Only a small percentage of donated clothes actually get resold in Goodwill stores. The remaining items (like torn T-shirts and holey or single socks) get separated and sold to textile recyclers. These recyclers break down the material and use it for things like home and car insulation.
