We have a situation here which is good. One of our local scrap metal places takes the metal trash our group brings in and pays us for it. It can be cans, washing machines, tin foil, etc. Each month the group has raised about $500 or so for the animal cause they work for.
By the way, a lot of plastic packaging is there to deter shoplifters. More for higher end things of small things other than groceries where it is clearly more marketing.
