Plastic Project - Week 1
Plastic has ben around since more than 200 years and it is a big problem for the environment. Since we were little we were exposed to plastic and to use it. Nowadays everybody knows that is a big problem and we started recycling. We made progress with the recycling but it’s not enough, because it’s still too much plastic out in nature.
The atoms are the lowest-low units of matter in chemistry. They are defining everything in the world. They are formed from a nucleus and one or more electrons bound to the nucleus. This nucleus is formed by one or more protons and neutrons. Hydrogen hasn’t got any neutrons, it’s an exception and it has 1 electron, 1 proton and 0 neutrons. These atoms in groups of two or more form the molecules.
Polymerisation is the process to create polymers. Polymerisation is a chemical reaction. When molecules unite themselves, they become monomers. They get combined to create larger molecules to create a polymer. In a polymer there are hundreds of molecules. Using heat and pressure, the molecules in the polymer expand and form plastic. Ethylene monomers are polymerized to form polyethylene polymer used for making carry bags, milk jugs, storage containers and trash barrels. Nowadays plastic is made of cellulose, coal, natural gas, salt, crude oil through a polymerisation or polycondensation process. Oil is a complex mixture of thousands of compounds and must be processed before it can be used. Plastics production begins with the distillation of oil in an oil refinery.
