Perhaps it is not surprising that New York City, one of the fashion capitals of the world, generates a lot of fashion waste. New Yorkers throw 200 million pounds of clothing into the trash every year. That’s the equivalent of 440 Statues of Liberty. Those clothes end up in landfills, where they will sit for at least 200 years.

This week, the Ellen MacArthur Foundation–an organization focused on making the entire economy more circular–is joining forces with the NYC Department of Sanitation, the NYC Economic Develop Corporation, and several fashion companies, for a citywide social media advertising campaign to help divert some of that waste away from landfills. These organizations are calling for New Yorkers to drop off their old clothing at one of 1,000 drop-off points throughout the city. (The full list is here, in case you’re interested.) They are also encouraging people to swap, sell, or repair their clothes.

Most of these drop-off points already existed, although about two dozen were launched to coincide with this campaign. Yet the EPA says that only 14.2% of clothes and shoes were recycled in 2015. Francois Souchet, the head of Make Fashion Circular, a division of the Ellen MacArthur Foundation, says the point of this new outreach is to show New Yorkers that this resource has been there for them all along.

“[O]ur real ambition was to show the potential of the existing system,” he says. “New York has many better options for old clothing than landfills. It’s a powerful opportunity to show what can happen when the industry comes together.”

Fast fashion brands including ASOS, H&M, Reformation, and Zara also helped support this campaign, which makes sense since they make clothes that are very closely linked to fashion trends, which means that customers often don’t have a reason to wear the clothes once they are out of style. Over the last few years, many of these brands have faced criticism–including from this publication–for helping spur on the environmental crisis by turning clothes into disposable items. Other companies that are part of this effort include clothing resale company ThredUP, and Lenzing, which makes eco-friendly fibers.

Clothing recycling hasn’t been widely available in the past. Most people donated their old clothes to organizations like Goodwill and Salvation Army, but only a proportion of those clothes end up being sold or given to people in need. A large amount ends up being sent to landfills anyway.
