".....Recycling of Polystyrene
Please note that due to present economic conditions, polystyrene food service packaging is generally not recycled. Polystyrene protective packaging and non-packaging non-durables (i.e., video/audio cassettes, agriculture trays, etc.) are the primary forms of polystyrene collected for recycling. There has been a decrease in the amount of polystyrene food service packaging recycled during this period. Non-food service packaging is not contaminated with food and other wastes as is food service polystyrene packaging, and therefore is more cost-effective to recycle. Presently, food service polystyrene packaging is not recycled because it is not economically sustainable. It is important to note that because of unfavorable economics, no other post-consumer foodservice disposable material, including paper and paperboard, is recycled in a measurable way......."

Use of single-use polystyrene in food service is environmentally unacceptable. The theoretical recyclability is moot because the recycling plants won't take it.
