At our home, we use the plastic bags we get from grocery shopping to store garbage. Technically, we are putting them to good use, but they are still a wasteful invention, and something needs to be done to prevent problems like this .
I don't think so. Just for money, a gas company wouldn't prefer to spend so much petroleum in plastic bags (cents) instead of gasoline (dollars). Moreover, I understand that bas are made of gasoline refinement process residues. That is, petroleum derived product you cannot use to make gasoline.
