IMPORTANCE OF PLASTIC:- Plastics are a subset of materials known as Polymers. These are composed of large molecules formed by joining many smaller molecules together (monomers). Other kinds of polymers are fibres‚ elastomers‚ surface coating and biopolymers‚ such as cellulose‚ proteins and nucleic acids. Plastics owe their name to their ability to be shaped to form articles of practical value by various conversion and forming processes. These are some peculiar properties of plastics materials‚ which

for thousands of years‚ and only recently has it started to take its toll on the environment. Chemists have been experimenting with different types of fuels and adding to gasoline to make it more efficient. This is when ethanol made its debut into the fuel industry‚ as an additive to gasoline. Ethanol is put into gas as a combatant against water‚ which can find its way into fuel tanks of vehicles. It reduces the effect that this water has on the health of the vehicle‚ and as a result increases gas
