Paper and aluminum alternatives to polystyrene foam food containers in New York City would cost almost twice as much, according to a study. A pending bill to ban PS foam containers could cost the city $100 million annually, "and a fraction of this cost would be borne by state agencies ... The replacements just can't do that [insulate hot and cold foods] as well, and the costs for that food service would nearly double," said Keith Christman, the American Chemistry Council's managing director of plastic markets. ACC is offering to help cities plan recycling initiatives for PS containers, Christman added.
