Targets set for FY2011
Status
Comments
GAB will be focusing on the reduction of electricity, thermal energy and water
consumption by 10% of the gap between actual consumption and its best
practice requirement, following the Heineken Utilities Benchmark Model.
In 2011, our bottle return rate increased by 7.7% from the
previous year. This has had significant impact on thermal
energy and water consumption.
We will be extending the Freon-free air-conditioning system
to the Technical offices in FY2011.
This was not done in FY2011. This project will commence
in 1st half of FY2012.

Lowering Our Water Consumption
Water is fundamental to our business. Our
consumption is in the form of the raw materials used
to produce our products and extends to the cleaning
process, packaging, production equipment and utility
installations. We have embarked on several water
saving initiatives and optimisation efforts to reduce
dependence on this valuable commodity. We reduced
our water consumption by 7.8% from 2009 to 2011.
This large saving from 2009 to 2010 came from the
reduction of cleaning required by better planning of
brewhouse operations. In 2011, our bottle return rate
increased by 7.7% from the previous year. This has
had a significant impact on our water consumption as
water is used in the cleaning process. This is one of
the main reasons why our water consumption did not
reduce by much in 2011.
All of our water is drawn from the municipal water
supply. Our wastewater is treated to ensure that no
harmful substance is released from the brewery.
We use two methods of biological treatment to
treat wastewater before it is released into the
river. The first method is an anaerobic treatment
where a biochemical reaction takes place in the
absence of oxygen resulting in organic carbon being
converted into carbon dioxide, methane and biomass.
The second method utilises an anaerobic treatment
where oxygen is associated in biological reactions
and results in organic carbon being converted to
carbon dioxide and biomass. This process ensures
that our COD (Chemical Oxygen Demand) levels stay
well below the 400ppm prescribed by the Department
of Environment. In 2010, our average COD level was
approximately 100ppm.
