In the past, # 6 polystyrene plastic and other plastics have been recycled at UST, but due to depressed plastic market, area processors will only accept # 1 or # 2 plastic unless we have a very large volume of # 6 plastic recycling. Polystyrene # 6, food service packaging is one of the most visible areas of public concern about the lack of recycling possibilities. Annual sales of Polystyrene food service packaging exceed 1.5 billion pounds according to the national recycling journal
Resource Recycling.
