I read a really good in-depth article about the life cycle of clothing, and clothing donation, and I can’t find it for the life of me. I’ve shared it on the SDMB a couple times and I may have gotten the link from here but I still can’t find it.
You can search google for “what happens to donated clothes?” and find a lot of interesting info, just in much shorter articles.
If you look at @am77494 's graph it shows we’re throwing away a ton of clothing. But it’s not Goodwill or Planet Aid that’s throwing away clothing, it’s consumers. There’s money to be made in reselling clothing or selling it as textiles. Sometimes the money goes to a for-profit company (ok much of the money goes to for-profit companies) and sometimes it goes to a non-profit.
People are asking on local Facebook groups every week where they can donate clothes to places that will immediately put these clothes on the backs of poor naked people in our area. They don’t want their discarded clothing being sold. As someone who has successfully sold a lot of clothes online, it’s a weird way of thinking. Clothing takes up a lot of space, especially if you want to present it in a way that prospective recipients can view, feel, inspect and choose the items that they need and want to wear. Clothing has seasons, too. And sizes. And occasions. I mean it’s great if you want to donate your size 2 summer wardrobe because you grew a little over the last couple years, but right now it’s winter and everyone at the women’s shelter is a size 8 or above and someone could sell your clothes to keep the lights on a little longer instead.
Here’s a good article about the lifecycle of a physical donation to Goodwill, focused on one store in the PNW.
Yes, Goodwill will take your donations and sell them at a profit, but the profit does go back to their charity (how well it’s distributed is something people like to argue about, but even when you look at it through a microscope it’s not nearly as bad as people perceive it to be). Goodwill also takes your un-sellable stuff and gets it into the hands of recyclers who will figure out a way to make a profit on the raw materials. And when all those avenues are exhausted, they take some of the profit from your good sell-able stuff and pay the fees to put it in a landfill.
So you can either toss your clothing directly into the landfill (well not directly - put it in your home trash can first), or find that gem of a clothing drive that has actual people in actual need of your actual clothing, or you can dispose of it via a store or donation bin that will either turn it into profit, charity, textile or trash but at least it had a fighting chance to stay out of the landfill.
If you can find the right charity that can get your clothes directly to people in need (and your clothes are worth re-wearing) then do that. But if you have stuff that is more niche or is in bad shape, you’re better off not burdening a small charity with them and diverting them through Goodwill so they can be re-sold or turned in to textiles. Goodwill has the better resources for that. Whatever you do, don’t just toss them. I mean if you’re going to throw it out anyway, what does it matter if someone makes a little profit off them?
