The Newton City Council approved a ban Tuesday on restaurants using disposable plastic stirrers and polystyrene food containers. The measure also prevents retailers from selling or distributing polystyrene foam disposable food containers and ban selling or distributing foam polystyrene packing material. The new ordinance goes into effect on Jan.1.

Newton City Councilor Vicki Danberg — one of the authors of the ordinance — says she is thinking of setting her sights next on a plastic water bottle ban.
