Recycling
Only five percent of the energy required to manufacture a new can is used when the same can is recycled. Therefore, an aluminium can should never end up as waste on a rubbish tip.
The story of recycling is the story of everything we don’t need to do again. Many materials are so good that they can be used over and over. A good example is aluminium, which we use for everything from aeroplanes and cars to pop and beer cans. The environmental benefit from recycling aluminium arises primarily from the amount of energy saved. Re-casting aluminium uses only five percent of the energy taken to manufacture virgin aluminium. In all, about 70 percent of all aluminium is recycled. By maximising recycling of various materials, Norway could reduce its greenhouse gas emissions by about 10 percent.
