How much hazardous waste is produced when PS is manufactured?
PS is an inert substance. In addition, the production aids used to make food service PS packaging are few in number and pose no known threat to human health or the environment. All additives to food service PS are used in compliance with US Food and Drug Administration (FDA) regulations. Production processes contain numerous emission control devices that capture and reduce emissions. Examples of the small amount of hazardous waste generated are solvents and inks from printing on finished PS products (industry uses water based and high solids inks), and any spills of intermediate chemicals that might be used to make PS in polymer plants.
