I don’t know off hand, but there is a bag recycling program at my local Loeb grocery store, so maybe I’ll ask next time I’m in. I did a bit of searching and found this awesome website that offers a lot of information about recycling plastic bags of all types, both stores and at home. This PDF file in specific explains to retailers why they would want to implement such a program. Apparently, they can sell them to companies who want to buy them for use in other products, and from that PDF: In North America, it’s a market worth $2 billion and growing at 14 per cent a year! But it’s still not a lot of money, 46 cents per kilogram of bags. Then again, free money is good money, and they get the benefit of being a company that takes environmentally friendly actions.
