Heat The wort-boiling process requires the greatest amount of heat. Other major opera tions requiring heat are the mashing process (the preparation of the mash), the clean sing of the bottles and the pasteurisation of the beer. A 3.1 percent reduction in the specific consumption of heat was achieved during the period between 1997 and 1999 (125 MJ/hl and 121 MJ/hl beer respectively). The total quantity of heat consumed in 1999 amounted to 6.0 billion MJ. The increase in con sumption in 1998 was due to the acquisition of breweries that were less energy effi cient than the existing Heineken breweries. The decrease to 121 MJ per hi beer produ ced in 1999 is largely the consequence of improvements implemented in these breweries. Another explanation for the improvement of the environmental perfor mance was the installation of new equipment; for example, more energy-efficient steam boilers were installed at the breweries of El Aguila in Madrid (Spain) and Zlaty Bazant in Hurbanovo (Slovakia). THERMAL ENERGY AND RECENTLY- ACQUIRED BREWERIES Newly purchased breweries do not usually comply with Heineken's standards for environmental care. Heineken devotes a great deal of attention to the implementation of improvements at these breweries. Fundamental issues such as employees' greater awareness of the importance of the environment and good housekeeping have made a contribution to substantial savings in the consumption of water, electricity and heat. Generally speaking, savings in the heat consumption are often feas ible at the newly-acquired brewer ies. The breweries acquired since 1998 are responsible for 17.9 per cent of the Heineken Company's European production. These new breweries have been able to re duce their combined heat con sumption by 6.7 percent within the space of one year whilst, at the same time, increasing their output. Consequently these breweries have been able to achieve an 8.7 percent reduction in their specific heat consumption. The generation of heat from fossil fuels makes the largest contribution to the brew eries' emissions and consequently a reduction in the heat consump tion has a positive effect on the environment.
