Many people are unaware of how many of the products we use every day come from petroleum and natural gas. In the United. States each family of four uses more than two tons of petroleum products annually. That "s almost 1200 lbs of chemicals each. Year for, every man woman and child in the United States - a staggering total of 225 billion pounds of chemicals, from petroleum. And to a, lesser extentNatural gas.
Of the vast amount of petroleum and natural gas we consume more than, 90 percent is burned as fuels. Only. About 5.5 percent is used for the manufacture of petrochemicals by the chemical industry. These petrochemicals vary widely. In their functions and includes such products as drugs detergents rubbers paints,,,,,, fertilizers dyes perfumes explosives,,, Food, preservativesArtificial sweeteners and agricultural, chemicals. Finally about 1.5, percent of the oil and natural gas is used as raw. Material for plastics. This small percentage translates into the production of billions of pounds of polymers that yield. Many different and useful products.
In post - World War, II years the United States was flooded with domestic and imported. Items of extremely, low costLow quality and limited, lifetime. This led to the image of "cheap plastics" with low durability. Today however the image,,, Of plastics has changed. Plastics perform an extremely broad range of functions from heart, valves and artificial kidneys. To ski boots nonstick, glues, surfaces supper, spacecraft, and parts and they compete with natural products in durability.No other materials expect plastics could perform all these different functions.
Plastics are replacing more and more parts. Of your car. The use of 1 lb of plastic can replace an average of 3.5 lb of metal in an automobile. An automobile with 400 lb. Of plastic substituted for metal will weigh about, 1000lb less which increases its gas mileage by about 3 mi / gal.The fuel savings are estimated to be about 160 million barrels of oil annually. That "s more than the total amount used. By the chemical industry as raw materials to make the polymers. As, another example synthetic polymer fibers are commonly. Used in fabrics for both, economical and practical reasons. If the world "s synthetic fibers were replaced, by cottonThis would require an additional 40 million acres of farmland.
Certainly the use of polymer plastics will increase. One. Can expect to find more applications in home construction and furniture because of the unlimited design freedom of, plastics. Plastics will be used more in drink containers and food packaging.The 700 billion gallons of liquids consumed each year in the United States will find their way to the consumer more and. More in plastic bottles. Diseased of malfunctioning parts of the body will be replaced by specialized plastic components. To a greater degree. We are indeed becoming a plastic society.
