Developing and implementing brewery plants that operate
efficiently and effectively in the long-term, while producing
optimum product quality together with a fast return on investments
and also low life-cycle-costs, are necessary because of increasing
of prices for raw materials, energy and transportation, as well as
a worldwide shortage of water and the moral commitment to save
resources. When we look at grain prices on the world market we
see that in 2006 the average world market price for grain was 146
EUR/t and in 2007 the price rose to 215 EUR/t. The same situation
we find for energy costs. In Europe the energy increase from 1992
to 2007 is about 11%, in North America 14%, and in South America
26%. In the past, the focus was mainly on saving investment costs,
but margins are exhausted, so now there is a big challenge for
brewing technology suppliers to reduce operational costs by a) new
layout and architecture structures; b) new ways of water treatment
(collecting rain water, reuse of process water and using in process
sections; c) high efficiency extract in wort technology; d) energy
saving in the wort boiling step; e) combination of heat and power
area; f) reduction of peaks and energy using with, for example,
energispar motor; g) no waste technology means reduced costs
for waste disposal, CO 2 neutral emissions due to residuals used as
biogenic fuel and hence benefits on emission trading equivalent to
savings of fossil fuel; h) use direct ammonia cooling systems and
buffer systems to reduce peak loads in the cold block area; i) and
so on. This presentation gives an overview of possible solutions for
technical equipment and design and process technology which is
necessary to fulfill the high technical and economical demands for a
brewery in 2010, which are water:
