End of presentation

Steel

Steel is made from iron ore which is found in some naturally occurring rocks. These rocks are mined and transported to factories to be melted in large furnaces to extract the metal.

CLOSE

Aluminium

Aluminium occurs in the earth’s crust as bauxite. Bauxite is a clay like rock which is mined and then refined; first into aluminium oxide and then into aluminium by electrolysis.

CLOSE

GlassCLOSE

Glass is made from the minerals sand, soda ash and limestone. These materials are extracted and transported to factories and melted together at very high temperatures.

Plastics

Example country: Saudi Arabia

CLOSE

Plastics are made from crude oil which is formed by decaying plants and animals in seas that existed millions of years ago and is found under the ground. This crude oil is drilled out of the ground, transported to oil refineries for processing and taken on to factories to made into plastics.

PaperCLOSE

Paper is made from cellulose fibres found in trees.  These cellulose fibres are usually sourced from recovered waste paper, forest thinnings and sawmill residues that result from the furniture and construction industries. Papermakers then transport this material to their factories to be pulped into new paper based products.
