Our challenge is to be more efficient
users of energy at all our sites.
Recent audits at the Australian
foundries have identified opportunities
to save up to 17% and these are
currently being investigated. Several
sites have come up with additional
energy and cost savings ideas.
With health, safety and
environment (HS&E) a core
value of Bradken, and an
integral part of effective
business and management
practices, actively working
towards making sure our
sites, equipment and work
practices are environmentally
responsible is part and parcel
of our responsibilities.
One of the biggest
environmental issues for
Bradken is energy – sources,
emissions and associated
costs. The company faces
increasing costs for energy and
raw materials, increasing legal
compliance costs, compulsory
energy efficiency measures
in some states, increasing
monitoring and reporting
requirements and more intense
public scrutiny. And if Australia
and America introduces a
carbon cost, energy costs will
go even higher.
Each year Bradken uses over
2 million gigajoules of energy,
at a cost of over $33 million,
creating around 220,000
tonnes of greenhouse gases.
The foundries account for
almost 90% of these energy
costs and emissions. Atchison
in the US and Runcorn in
Queensland Australia are
responsible for 30% of the
energy cost and 40% of the
energy use.
At this stage, renewable energy
resources, such as solar and
wind electrical power, are
not economic or practical for
our energy demands when
compared to coal and gas
generated electricity. Bradken
is involved in the development
of ‘green energy’ technologies,
for example, by supplying
specialised steel castings for
wind power turbines. There is
irony in the fact these types
of green technologies could
not exist without foundries and
heavy engineering facilities.
Examples of recent energy
saving initiatives at Ipswich
include the replacement
of skylights, reducing the
amount of artificial lighting
required during the day and the
installation of a new inverted
ladle heater. At Runcorn, a new
heat treatment oven layout is
expected to improve efficiency
and reduce gas use.
As individuals we can
contribute to energy and
cost savings, by turning off
lights and equipment when
not in use, reporting faulty
equipment as soon as possible
and reducing air conditioning
