FACTS ON PLASTICS
z Over the lifetime of averge car, plastic parts saves 650 gallons of gas due to
their lighter weight.
z By using plastics in their packaging products manufacturers saves enough
energy to power a city of 1 million homes for 3 & 1/2 years.
z Today’s most innovative medical procedures are dependent on use of plastics.
z Plastic Artificial hips & knees helps smooth working & trouble free joints.
