While you can donate old T-shirts andjeans, you\'re likely to just toss your used socksin the trash. But now, Smartwool wants you togive them your old socks—from any brand—sothat they can recycle them into filling for dogbeds.rn“A lot of organizations won\'t take donatedused socks, so oftentimes consumers just don\'tknow what to do,”says Alicia Chin, the head ofsustainability and social impact at the company.Many who responded to that Smartwool surveysaid they threw out one to three pairs of socksa year, so the company began looking for a solution, and partnered with Material Return, a North Carolina-based company that turns textile waste into new products. Smartwool decides to create dog beds, though it hasn\'t ven-tured into pet products before, because of how that item fits with their“fun loving, outdoor”brand, Chin says.
