6.6 Thermal energy
Thermal energy is needed at various stages in the brewing process, mainly for boiling
wort, washing bottles and pasteurisation. The heat is obtained from fossil fuels - chiefly
from gas or oil and, in a few cases such as in China, from coal.
Specific thermal energy consumption by our breweries decreased by 7% in
2001, from 125.8 MJ/hl to 118.5 MJ/hl beer. Most of the savings were achieved by
employing heat recovery methods, for example at St. Omer (France) where a thermal
wort vapour compression system has entered service. Further more the switch from
coal-firing to more efficient oil-firing (Poland) and introducing 'good housekeeping'
measures (China) also contributed to the reduction.
Thermal energy is needed in maltings for kilning malt and in soft-drink plants
for bottle-washing and pasteurisation. Specific heat consumption by our maltings
decreased to 3,053 MJ/tonne in 2001, down 3% on the year before.
