Nature and the environment
At different stages of a products life-cycle the material used
may have different impacts on the environment and as
a result it is important that designers and manufacturers
consider this when designing and manufacturing new
Raw Materials Extraction – damage can be caused to
the environment by the extraction of raw materials.
E.g. mining for metals, de-forestation for wood , oil
Materials Processing – process of turning raw materials
into usable materials. E.g. refining crude oil into plastics,
processing wood into paper and smelting metal ore into
metal alloys. This can use up huge amounts of energy as
well as producing by products and waste materials
Disposal – products which are not made of recyclable
materials are thrown away in landfill sites.
Recyclable products however are broken down and their
parts are re-used again for example the Dyson Hoover
is collected by Dyson to shred the thermoplastic parts
for re-use. Those products which can be re-used may be
repackaged and used again.
Greenhouse gases are gases that trap and emit infrared
radiation emitted from the earth into the atmosphere.
The natural greenhouse gases in the Earth’s atmosphere
are water vapour, carbon dioxide, methane, nitrous oxide,
and ozone. Other greenhouse gases such as gases used in
aerosols are created exclusively by humans.
