San Francisco environmental supervisors approved a measure that bans food containers, coolers, kiddie pools, and peanut packages made from polystyrene.
This prohibition is described as the most extensive by a US jurisdiction, on cheap material for product packaging.
The measure is already applied in other parts of the United States such as Washington, Virginia and Maryland.
Polystyrene is also used to keep drinks hot or cold. The decomposition of this lightweight plastic is extremely slow and pollutes waterways, damaging marine fauna and flora and birds.

Critics say the legislation does nothing to stop Styrofoam-packed items, heaters and computers from entering the city.
Known as “expanded polystyrene” is the latest plastic to be targeted by cities and counties, much like the disposable plastic bag, which San Francisco banned in 2007.
