New York (CNN) - Mayor Michael Bloomberg, known in New York City for his tough regulations on everything from large sodas to smoking in Central Park, proposed a new target during his final State of the City speech Thursday: plastic foam containers.

"Styrofoam increases the cost of recycling by as much as $20 per ton because it has to be removed," the mayor said. "Something we know is environmentally destructive, that is costing tax payers money, and that is easily replaceable, I think, is something we can do without."
