Our Commitment to Good Environmental Performance
Thermal Energy Conservation
Heat is extensively used in the production process
as it is required for brewing, cleaning bottles and
also pasteurisation. Currently, most of our heat
requirement is generated from natural gas sourced
from the national natural gas pipeline which we
have been tapping since 2007. We switched from
fuel oil to natural gas to reduce our dependence on
the former, and simultaneously cut down our carbon
dioxide emission levels. In addition to natural gas, we
also use renewable gas, mainly biogas obtained from
the anaerobic treatment of wastewater at our water
treatment plant, to generate some of the heat that
we require.

During the period under review, our specific thermal
consumption was reduced by about 6.1% compared
to the previous year. We will be focusing on further
reducing thermal consumption by 10% of the gap
between actual consumption and its best practice
requirement, following the Heineken Utilities
Benchmark Model.
A TPM team launched to increase the Chemical Oxygen
Demand (COD) loading at the waste water treatment
plant contributed towards increasing the biogas
generated which in turn helped reduce the amount of
natural gas that was required by the brewery.
CASE STUDY
New Economiser for Boiler-9 and Boiler-10
The production process at GAB uses heat
generated by the combustion of natural gas in
the furnace. The combustion process causes a
substantial amount of heat, known as flue gas,
to be released into the environment as ‘waste
heat’.
Using the zero-loss TPM mindset, we installed
an Economiser to reduce the fuel consumption
required by the boiler. The Economiser also
further improves the overall efficiency of the
boiler and reduces the temperature of the flue
gas emitted into the environment.
The reduced environmental impact of the
economiser is substantial as this area
contributed the biggest chunk of the reduction
of our consumption of thermal energy.
