Recycling
Process
- Metals recycling is a
‘pyramid’ industry which includes many small, family owned companies, as
well as large, international businesses.
- All metals are made
from non-renewable minerals and ores (such as iron-ore) found in the
soils and rocks of the earth's crust.
- Metal products such
as steel and aluminium cans can be recycled through the kerbside
recycling system.
- Metals recycling
protects the environment and saves energy.
- Steel cans including
aerosol (spray) cans, can be recycled through the kerbside collection
system.
- The manufacturing
processes generally do not change the properties of the metals (except
in alloys and other mixtures), only the shapes. Therefore recycling
metals is a simple process of melting and reshaping.
- Aluminium is made
from an ore called bauxite. Australia is one of the largest producers of
bauxite.
- Converting bauxite to
aluminium is not as simple as melting the ore and recovering the metal.
Technology
- Melting separation
technology is the technology of separating the element containing the
radioactive isotope in the radioactive metal waste, and reducing
concentration of radioactivity.
- A new duallabeling
technique in which intracellular and extracellular metal pools in prey
cells are separately labeled with 2 isotopes of a single trace metal.
- Oxygen Sparging
Method is the metal recycling process that uses a pyro-metallurgical
metal separation technique (without radio nuclides). This process
utilizes the difference of the oxygen affinities between metals.
- Dragout reduction and
recovery is an important P2 technique for metal finishing. It is a
simple technology used by metal finishers to return plating chemicals to
their original bath before they become integrated into a waste stream.
- A new technique is
available to predict where metal quality is lost in the recycling
process could make recycling cost-effective and reduce the need for raw
material inputs.
Market
- Metals recycling is a
£4.5billion UK industry, processing ferrous and non ferrous metal scrap
into vital secondary raw material for the smelting of new metals. The
industry employs over 8,000 people and makes a net contribution to UK
balance of trade.
- Metals recycling
supplies a major worldwide industry. Manufacturing of metals continues
to be one of the largest UK manufacturing sectors, employing more
people, and contributing more value to the UK economy, than motor and
aerospace combined.
- Recycled materials
account for between 30 and 60 percent of the total world consumption of
metals and are a major component in the availability of minerals and
metals for future generations as minerals and metals are not “consumed”
in the way some other nonrenewable resources are.
