School districts in New York, Los Angeles, Chicago, and Dallas also are included in the project. Together, they will remove 225 million plastic foam trays a year.

School districts have relied on the foam trays because they cost 4 cents apiece, compared to their compostable counterparts that average about 12 cents each. The compostable plates bought through the alliance cost about 5 cents each.
