Governments should tax products for their disposal costs. Eventually everything needs to be disposed of so charge it at purchase time and remove the costs the individual pays later for garbage collection. This would mean products that don't use wasteful packaging become cheaper and people would buy less junk.
Every board room: "Just put some soil and seeds into this used plastic bottle and it becomes a handy plant pot - therefore it has an extended use and shouldn't need disposing of, hence zero disposal tax!"
I do exactly that with pails/buckets and plastic beer cups.
