Bradken’s environmental
strategy has a role for
everyone in reducing
waste and increasing
1. Do it once and do it right
Having to redo things, whether
memos or castings, wastes
time, manpower, energy
and raw materials. It’s worth
spending a few moments
more to get it right first go.
2. Put waste in the right bins
Avoid wasting resources
through contaminating
recyclable materials with the
wrong waste. For example,
wood in a scrap metal bin, or
plastic in the paper bin, prevents
the waste being recycled.
3. Think energy saving
Save energy by turning
equipment off when not in use.
4. Report faulty equipment
Equipment that doesn’t
operate as it should wastes
time, manpower, energy
and resources.
5. Report leaks and spills
Leaks of compressed air,
water, gas and the like can
result in significant resource
wastage and contamination
of the site and the storm water
system. Early attention to
cleaning up spills may mean
being able to reuse the material.
Waste and resource
management are among
the main environmental and
cost issues for foundries
and engineering operations.
Governments around the
world are setting lower landfill
targets. Several have policies
of zero waste to landfill by
2020 and have introduced
levies that promote waste
minimisation and recycling
schemes by increasing the
cost of waste disposal.
The benefits to both Bradken
and the environment of
improving our performance
in waste and resource
management are clear. It slows
the rate at which landfills are
filling up, reduces raw material
costs and the rate at which
valuable resources are
consumed and reduces
emissions. In addition,
reducing our energy use also
lowers costs and decreases
greenhouse gas production.
Here are some of the current
recycling and reuse practices
in operation at Bradken
All metal used to produce
the castings is now
processed through our
Metal Recycling business.
This would otherwise have
been sent to landfill.
In line with our product buy-
back plan, when products
are worn out we buy them
back from customers and
recycle them to produce
new products.
We extend the life of our
mining buckets and heavy
equipment by refurbishing
them at our facilities at
various locations.
Foundry sand on most sites
is recovered and re-used up
to 10 times. Our American
sites lead the way in sand
Henderson site even
separates chromite sand
and recycles it on site for
their site and Welshpool.
Foundry sands are no
longer able to be reused
in our processes and can
be recycled into other
industries, reducing the
amount of waste sand sent
to landfill. For example,
waste sand is used in
cement kilns to make
Portland cement, in bitumen
batching plants for bitumen
on roads, as road base,
construction fill, pipeline
and mine site backfill, as
well as in compost and
as a soil additive in the
landscaping industry.
Bradken sites recycle a
wide range of materials
– paint and solvents, oils
and oily water, cardboard
and paper, tins and drums.
Plastic welding reels and
shrinkwrap are collected for
shredding and reprocessing
as recycled plastic. Arc
furnace electrodes are
collected and crushed so
the foundry can use the
graphite in the furnaces.
Pallets, crates and other
scrap timbers are either re-
used or crushed for mulch.
Some have even been
converted to worm food.
Last year122,000 tonnes of waste were removed
from Bradken sites at a cost of over $4 million.
44,000 tonnes of this waste was able to be recycled.
