Replacing your worn-out old comforter? Yes, you can recycle it -- and it's easy. Whether it's down feather, polyester or a combination of both, all you have to do is bring your old comforter to a textile recycler, or even easier, Goodwill. Almost any kind of fabric or textile can be recycled. The recyclers tear apart old clothes and items like comforters and turn the materials into things like upholstery filling, cleaning rags, carpet padding, building materials and insulation for cars. Anything that can't be recycled is safely disposed of in a landfill. But the best part? Goodwill makes money for their charitable works by selling your old comforter to textile recyclers.
