Restaurant, manufacturing and recycling groups have sued to stop New York City’s proposed ban on plastic foam containers.

Coalition members from The Restaurant Action Alliance NYC said Thursday their lawsuit filed in Manhattan state supreme court seeks to block the ban that’s set to go into effect July 1.

Court papers filed by attorney Randy Mastro say Mayor Bill de Blasio was predisposed by politics to stop the sale of plastic cups, food containers, plates and other items.

Mastro served as a deputy mayor under Rudolph Giuliani.

The ban was to take effect unless a yearlong inquiry found it could be recycled effectively. The Restaurant Action Alliance NYC says in court papers plastic foam recycling technology exists.

City officials say polystyrene foam causes real environmental harm.
