Malting
RESULTS
6.4 Water
Water is in quantity the most important raw material used in the production of beer
and soft drinks. It is also used for cleaning process tanks, packaging materials (kegs,
cans and bottles), production plants and pipelines. Water is used in our maltings for the
conversion of barley to malt.
Specific water consumption by our breweries in 2001 was 5.7 hi of water per
hi of beer, a decrease of 7% compared with 2000. This reduction was partly due to the
installation of water meters at our Zagora (Bulgaria) plant, which has enabled us to
monitor water consumption more accurately. The introduction of water recycling at our
Massafra (Italy) plant also resulted in decreased water consumption. The breweries that
have not yet reached their targets will continue their water-saving efforts. Now that a
large number of our breweries have reached the target of 7 hl/hl, an even lower target
will be set for the years ahead.
Specific water consumption at our maltings was reduced from 5.6 m3/tonne in
2000 to 5.0 m3/tonne in 2001. Our malting in Bulgaria, where water-savings have been
achieved in the steeping process, accounted for a large proportion of this improvement.
Specific water consumption for soft-drink production remained fairly constant at 3.6 hl/hl.
