Reducing Our Electricity Consumption
At GAB, electricity is used for refrigeration, water
treatment and also to operate our compressors and
other machinery. It is also used to liquefy CO ² , power
our office equipment and light up our workplaces.
During the period under review, we reduced our
electricity consumption at the brewery by 7.9%.
Our goal is to reduce our consumption by 10% of
the gap between actual consumption and its best
practice requirement, following the Heineken Utilities
Benchmark Model.
Our TPM teams have been responsible for the
reduction in our electricity consumption. Other
initiatives include the de-aerated water plant
process to reduce electricity in the cooling plant;
and proactive measures taken by our Kaizen teams in
tackling compressed air leakages and restoring the
cooling plant plate exchanger evaporators.

Upgrading of CO ² Plants
CO ² is a natural product of the fermentation process
in the manufacturing of our products. We recuperate
the CO ² from this process to use in the bottling of
our products.
Prior to the upgrade of the CO ² plants, we had to
supplement our CO ² requirements through purchases
from third parties. This, however, presented us with
supply issues where we faced shortage one year. We
managed to turn the challenge into an opportunity by
investing in the upgrade of the CO ² plants.
Upgrading our CO ² collection process has minimised
the emission of CO ² and reduced electricity
consumption associated with the collection process.
We are now self-sufficient for CO ² supply.
Reducing Emissions
Non-renewable fuel generates bi-products such as
CO ² , nitrous oxide (NOx) and sulphur oxide (SOx)
which contributes to climate change. Our initiative to
switch to natural gas has resulted in a reduction of
CO ² by 3%. NOx and SOx each remained unchanged
compared to the previous year.
CASE STUDY
Freon Air-conditioning System
GAB has introduced a new air conditioning system
that uses alcohol water. The medium is chilled
with liquefied ammonia via a heat exchange
from the cooling plant process, against the
conventional process which used Freon (R-22,
ozone-depletion refrigerant) for air-conditioning.
The new system has no ozone-depletion and no
global-warming potential.
The creative system uses our existing resources
more efficiently, reduces our environmental
impact, and also drastically reduces air-
conditioning maintenance costs. With this
initiative, GAB has taken a significant step in
a positive direction towards environmental
conservation and we are proud to be able to play
our part as a responsible brewer.
We have successfully implemented the new
system at our newly-renovated Engineering and
Packaging offices and will be extending it to the
rest of the Technical offices in the near future.
