Styrofoam foodware has been banned on the campus of San Benito High School. Polystyrene can contain such chemicals as styrene and benzene, which (when heated) can release those neuro-toxins. School Board members further say that styrofoam is expensive, and difficult, to recycle.
Although the cafeteria used to use styrofoam cups and bowls, they now use compostable paper goods (for all of the food, and beverages, they serve).
