Once upon a time Coca cola used to sell coke in glass bottles that you would then give back to them, they'd wash them, sanitize them and sell them again. You'd pay a small deposit on the bottle that they'd then give back to you. They had bottling centers all over the place.
They switched to plastic bottles because it was much cheaper to let the government handle the garbage problem
