When it's time to replace a worn-out comforter -- whether it's down feather, polyester or a mix of feather and faux -- what do you do with it? The good news: It's recyclable. Old textiles, including clothes, blankets and, yes, comforters, are recyclable materials that can be made into new products. Usually, it's used as upholstery fill for furniture or cars, building materials or cleaning cloths. But whatever it is, old comforters should not be tossed out. Instead, put your bedding into a clean garbage bag and donate it like you would clothing to charities like Goodwill. The nonprofit will resell it to textile recyclers.
