realises the priority of decreasing the amount of water used for beer production
with a simultaneous increase in production. At every brewery of Kompania, water
consumption calculated for a unit of the beer produced is monitored. The observa-
tions are carefully analysed and, on that basis, new solutions are introduced thanks
to which the values keep decreasing. In 2013 the water consumption indicator
for the whole company was 2.96 hl of water per a hectolitre of the beer produced
(data for 2013). By contrast, 10 years ago the indicator was 4.6 hl per a hectolitre
of beer. Water is supplied to individual breweries of Kompania Piwowarska from
its own intake stations (underground water) or from the city water supply. In order
to adjust its parameters to the beer production requirements, it is subjected to treat-
ment processes (Table 4 ).
All three plants of Kompania are successful in reducing the amount of waste-
water produced. In the last few years each of the breweries has managed to
decrease the quantity of wastewater by a few dozen per cent. In Białystok, the
amount of the wastewater generated has fallen by as many as 51 % in 7 years. The
wastewater treatment principle is obeyed by every brewery before it releases it to
the environment. When the existing infrastructure allows to do so, the treatment
process is carried out at the brewery's premises. The one in Tychy has a modern
wastewater pre-treatment plant at its disposal. It is based on anaerobic methods
of treatment with granules. As a result of anaerobic fermentation, biogas is made,
stored and, then, used as fuel of standard value to heat boilers. Wastewater from
the other breweries is directly sent to the municipal treatment plants.
