Detailed explanation-1: -Most plastic in use today comes from hydrocarbons derived from crude oil, natural gas and coal – fossil fuels.

Detailed explanation-2: -Plastics are produced from natural gas, feedstocks derived from natural gas processing, and feedstocks derived from crude oil refining.

Detailed explanation-3: -Plastics today are mostly made from natural materials such as cellulose, coal, natural gas, salt and crude oil through a polymerisation or polycondensation process. Going forward, plastics will increasingly be made from waste, renewable materials or CO2. Plastics can be classified into various types.

Detailed explanation-4: -Ethylene is at this point still a gas and needs pressure and a catalyst to turn it into polyethylene, a resin. The process by which polyethylene is made from ethylene is known as polymerization. The term “plastic” suggests one material, but there are actually hundreds of different plastic polymers.

Detailed explanation-5: -In its raw state, plastic is made up of a range of organic polymers, including polyethylene and ethylene. In a soft state, plastic can be molded into the desired shape and then cast into a solid state. “The different raw materials of plastic bottles include polyethylene terephthalate and high-density polyethylene.
