The term “plastics” includes materials composed of various elements such as carbon, hydrogen, oxygen, nitrogen, chlorine, and sulfur. Plastics typically have high molecular weight, meaning each molecule can have thousands of atoms bound together. Naturally occurring materials, such as wood, horn and rosin, are also composed of molecules of high molecular weight. The manufactured or synthetic plastics are often designed to mimic the properties of natural materials. Plastics, also called polymers, are produced by the conversion of natural products like oil, natural gas, or coal. The plastics industry is the third largest manufacturing industry in the United States. Yet one big negative remains: plastics are non-biodegradable. That means when thrown away, they are with us forever.
The plastics industry realized more than 20 years ago that recycling plastics was a necessity for our planet. Can you recognize the important facts about recycling plastics? ALL BUT ONE statement is true. That is
A) Every ton of plastic bottles recycled saves about 3.8 barrels of oil.
B) Only plastics marked with the #1 resin code can be recycled economically.
C) Recycled bottles and containers are used to produce lumber products that can be used as an outdoor building material.
D) Because different types of plastic must be recycled separately, the numbers on plastic containers are there to help consumers and recycling centers with sorting.
