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.

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. ...BARRY KNIGHT
