Detailed explanation-1: -Synthetic plastics are derived from crude oil, natural gas or coal.
Detailed explanation-2: -Plastics are made from raw materials like natural gas, oil or plants, which are refined into ethane and propane. Ethane and propane are then treated with heat in a process called “cracking” which turns them into ethylene and propylene. These materials are combined together to create different polymers.
Detailed explanation-3: -Plastics are produced from natural gas, feedstocks derived from natural gas processing, and feedstocks derived from crude oil refining.
Detailed explanation-4: -In the US, chemists at Rutgers University have developed a new technique using electrocatalysts containing nickel and phosphorus to combine water and carbon dioxide with electricity to produce complex carbon-containing molecules that can be used to produce plastics and other products such as pharmaceuticals.
Detailed explanation-5: -It is made by linking short strands of DNA with a chemical derived from vegetable oil, which produces a soft, gel-like material. The gel can be shaped into moulds and then solidified using a freeze-drying process that sucks water out of the gel at cold temperatures.
