Most plastics are made from crude oil (coal and natural gas can also be used), Crude oil is found deep underground and by drilling deep down into the rock oil is brought to the surface and then shipped or piped from the producing regions to refi neriesThe crude oil is then refi ned to make petrol, diesel and motor oils for cars and lorries.
Out of every 100 litres of oil refi ned, 10 litres are used to make plastic.Everything is made up from tiny particles called atoms. To make plastics, the atoms that make up oil are pulled apart and separated. They are then joined back together in long thin chains of atoms called polymers.
By changing the order of the atoms in the polymer chains, different kinds of plastic can be produced, Plastic is then moulded into thousands of different shapes. There are three main ways of moulding plastic, by injection, heat or being blown.
