GOLDTOE Socks, a trademark owned by apparel manufacturer Gildan, recently announced a free sock recycling program. The company teamed up with TerraCycle, a private U.S.-based recycling business, for the initiative.

The program will offer consumers a way to recycle used socks from any brand. Recycled socks will be used to manufacture new socks. In return for sending in their old socks, people will receive points to use as donations to non-profits, schools, or a charitable organization of their choosing, according to a press release. It is a free recycling program that is open to any individual, office, or community organization.

Here’s how it works: Those interested can head over to the TerraCycle website to sign up. Once there, users download a free shipping label. Then it’s as simple as mailing used, clean socks to TerraCycle. The company notes that while it will take care of the recycling, enrollment limits apply. It adds that if the program is full, you will be added to a waitlist.

“While commonplace in our lives, socks can be difficult to recycle,” said TerraCycle CEO and Founder Tom Szaky in the press release. “Through this program, GOLDTOE is encouraging consumers to embed responsible practices into their daily lives by cleaning out their drawers and doing some good for the planet and their community, all without compromising convenience.”

The partnership with TerraCycle is just one of Gildan’s sustainability initiatives. The company announced a new set of goals committing to further advances in different areas, including circularity, in 2022.

“We are pleased to partner with TerraCycle to provide customers with an innovative yet simple way to divert waste from landfills by giving new life to their socks,” said Gildan’s VP of marketing, Emma Budzisz, in a press statement “At GOLDTOE, as part of leading apparel company Gildan, we believe that clothes should be made with respect from start to finish, including the end-of-life of our garments.”
