5.2 Energy consumption
5.2.1 Breweries
Heineken's production facilities make use of two kinds of energy: electricity and ther
mal energy. In most instances telectricity is purchased from external suppliers.
However, one brewery possesses an on-site power station which not only generates
electricity, but also produces steam. Two facilities obtain their heat from an external
supplier.
Electricity
Heineken uses electricity for refrigeration, wastewater treatment, C02 recovery, the
production of compressed air, electric motors in the packaging departments and in
the offices.
In spite of an increase in the use of electrical equipment, we have nonetheless been
able to achieve a reduction in the specific consumption of electricity. This reduction
was achieved by virtue of improvements in scale, improved working methods and
inspections and the installation of new, low-energy equipment.
For the purposes of comparison, our total European electricity consumption of 506.9
million kWh is sufficient to provide a city like Helsinki with electricity for two weeks.

■IN AN AFRICAN QUOTE WE SAT: THE WORLD IS NOT OURS,
THE AIR IS NOT OURS. IT'S A TREASURE WE HOLD IN TRUST FOR FUTURE GENERATIONS.
AND I OFTEN HOPE, WE WILL BE WORTHY OF THAT TRUST.'
BIOGAS
Biogas is released during the
anaerobic digestion of organic
matter in wastewater treatment
installations. The biogas is re
covered and used as an additional
fuel process, thereby enabling the
brewery to achieve savings in its
consumption of fossil fuels. Seven
of our European breweries are
currently equipped with a waste
water treatment facility which pro
duces biogas. Heineken's brewery
in Den Bosch (the Netherlands),
for example, obtains more than
4 percent of its total energy re
quirements from this sustainable
source of energy.
