environmentally friendly diesel
Alcoa Anglesea is trialing an environmentally
friendly diesel product to operate all of the major
equipment at its coal mine in a bid to reduce
greenhouse emissions across the site.
As part of the Alcoa Anglesea’s commitment to
environmental improvements, the mine is
undertaking a six-month trial of the diesel product
for all of its earthmoving equipment fleet.
The product, commercially known as FLEX, has
the potential to deliver substantial reductions in
emissions:
> 28% reduction in CO2 emissions;
> 20% reduction in particulates;
> 35% reduction in SO2; and
> reductions in hydrocarbons and NOx.
Based on the 1.7 million litres of fuel used by Alcoa
Anglesea for its mining operations each year,
emission reductions that could be achieved are
estimated at CO2 emission reductions of around
1150 tonnes, CO reductions of 51 tonnes,
particulate matter reductions of 5 tonnes together
with additional reductions in hydrocarbons, NOx
and SO2.
Whilst to use this product Alcoa Anglesea had to
move away from a national contract, the new fuel
can be used without any additional cost for the
business.
What is FLEX?
It is an ester-based oxygenated fuel made from
vegetable oils (canola) and animal fats (tallow).
There are many advantages for using
environmentally friendly diesel such as FLEX as a
transport fuel. For example, it can be produced
from domestically grown oilseed plants such as
canola. Producing it from domestic crops reduces
Australia’s dependence on foreign petroleum,
increases agricultural revenue and creates jobs.
Today’s diesel engines require a clean-burning,
stable fuel that performs well under a variety of
operating conditions. Products like FLEX are the
only alternative fuel that can be used directly in any
existing, unmodified diesel engine. Because it has
similar properties to petroleum diesel fuel, it can be
blended in any ratio with petroleum diesel fuel.
Successful alternative fuels fulfil environmental and
energy security needs without sacrificing operating
performance. Operationally, FLEX will perform very
similar to low sulphur diesel in terms of power,
torque, and fuel without major modification of
engines or infrastructure. The only issue in the
short term is ensuring that fuel filters are changed
early as FLEX will clean out the fuel lines.
If the trial is successful, the mine’s equipment will
permanently switch from extra low sulphur diesel
to environmentally friendly diesel.

OUR ENVIRONMENT AND OUR EMPLOYEES..
Barry
Barry,, why would we initiate a trial of envir
environmentally
onmentally
friendly diesel in the mine?
The environmental benefits are significant, particularly the 25%
decrease in greenhouse gas emissions. To do so with no added
cost, makes it a win-win scenario for the business.
Your time at Anglesea has come to an end.
In a way, yes. I will still have some Anglesea responsibilities, but
will be based at Pt Henry as the Senior Environmental Scientist.
Highlights?
Achieving two consecutives years without a non-compliance is
my highlight, and also our work on community engagement, the
first EIP for Anglesea, environmental reporting and waste & water
reductions. The people at Anglesea have been very friendly and
great to work with.
Final thoughts?
Anglesea is a terrific location to work and the environmental
performance over the past few years is something we can all be
very proud of - there is some world class work occurring here.
There is also significant challenges ahead, but I’m sure with
everyone’s full commitment, Anglesea can operate sustainably
for many years.
