The polystyrene manufacturing process is the 5th largest creator of hazardous waste. The process of making polystyrene pollutes the air and creates large amounts of liquid and solid waste. Polystyrene is manufactured with HCFC-22, a green house gas that affects the ozone layer, and petroleum, a non-sustainable and highly polluting resource. HCFC-22, a type of CFC, depletes the earth's ozone shield 10 miles or higher in the sky.
