How many times do I have to say this, ban metal resale to the general public and remove the can deposit. You get nothing for redeeming any sort of metal. After you complete your home renovation and remove some older copper piping you get nothing, just toss it on the curb for garbage pickup.

The only people that will be allowed to benefit through the redemption of scrap metal are licensed contractors who will require permits to remove, transport, and resell materials. They will pay yearly renewal fees to continue these types of operations.

If you aren't in the construction industry, any reasonable person wouldn't waste their time taking metal to the scrapyard for a couple extra bucks, just as taking pop cans back to the store is a complete waste of time, energy and gas.
