There’s more to those parking-lot collection bins than pleas for clothes and books; they’re part of a billion-dollar global textile industry. Most are legit; some are just making a buck.

So throw it all in there: socks with holes, old underwear, stuffed animals — any household textile. The Blab Lab talks to two area textile recycling experts, Kevin Fisette of Goodwill Industries of Rhode Island and Larry Groipen of ERC Wiping Products.
