Plastic wrap is, quite frankly, a menace. It's a binding agent for urban tumbleweed. In its PVC form, it can leach its plasticizers (the toxic chemicals that make it stretchy) into food. These things are bad, but really, what about the waste? It's astonishingly wasteful. Even if we had a way of reusing it, it's nigh on impossible to unpick a ball of scrunched-up wrap.
