Specific electricity consumption of breweries continued to decline in 2002, falling 2%
compared with 2001 to 10.3 kWh per hl of beer, reflecting the savings predominantly
achieved via investment projects at 's-Hertogenbosch (Netherlands) and efficiency
gains in Shanghai (China).
Our maltings reported a 1% decrease in specific electricity consumption, from
123.9 kWh per ton in 2001 to 122.5 kWh per ton of malt in 2002.
Specific electricity consumption by our soft-drinks plants was 10% higher, up from
4.6 kWh to 5.1 kWh per hi of soft drink, partly due to the replacement of packaging
machines at Bunnik with new equipment which uses more power and the additional
pumps installed in the new syrup hall.
Specific thermal energy consumption by our breweries continued to decline, falling
to 116.5 MJ per hi of beer in 2002. This improvement was mainly due to the new
equipment installed at our breweries in Madrid and Den Bosch.
The figure for our maltings in 2002 was 2,984 MJ per ton of malt, which represents
a decrease of 2% compared with the year before and was achieved through technical
improvements such as more efficient insulation and the overhaul of the heaters at
two maltings in Slovakia.
Specific thermal energy consumption for our soft-drink plants rose from 38.1 MJ per
hi in 2001 to 40.8 MJ per hi of soft drink in 2002, mainly due to the alterations at Lamia
and our new plant in Skopje.
Carbon dioxide emissions
Total carbon dioxide emissions increased from 684 thousand tons in 2001 to 698
thousand tons in 2002, corresponding to specific emissions of 7.8 kg per hi of beer
and 2.4 kg per hi of soft drinks. The equivalent figure for our maltings was 165 kg
per ton of malt. Because the trend in carbon dioxide emission is related to the trend
in thermal energy consumption, it was lower for our breweries and maltings and
slightly higher for our soft-drink plants.
By-products and waste
Output of residual industrial waste was 24% lower last year, down from 101 thousand
tons in 2001 to 76.4 thousand tons in 2002, with the African region recording the
biggest decrease, of almost 25 thousand tons. Nigeria, where a good start has been
made by selling brewers' grains to local farmers instead of dumping them at landfill
sites, was largely responsible for this improvement.
