Swedish Stockings is a sustainable hosiery company based in Sweden. Most of the modern hosiery uses nylon yarn, which is created from “an environmentally harmful petroleum-based manufacturing process.” According to their site, Swedish Stockings creates their products from both pre and post-consumer nylon waste. Their factories are zero waste as well. They have their own recycling program for any old ripped stockings. They can be any brand of hosiery as long as there are 3 or more pairs of stockings. Once you mail the stockings to the recycling center listed on their website, you will receive a discount code.
