ZOETERWOUDE GETS ITS
OWN ENERGY SOURCE
Kirin's President
visits Heineken
THE PRIZE
On 31st May this year Dr. Bela Julesz, of the United States, and
Professor Dr. Werner Reichardt, of West Germany, were
presented with the Dr. H.P. Heineken Prize by H.R.H.
Prince Claus of the Netherlands.
This was the first time that the prize had been awarded to two
scientists at the same time.
Both prizewinners have achieved outstanding results in their
research into the visual perception of depth and movement.
Dr. Bela Julesz
Prof. Dr. Werner Reichardt
From now on our brewery in Zoeterwoude (Holland) will have its own source of energy on tap.
On the site of this brewery a combined heat and power generating plant, enabling a saving of
around 24% on the energy bill, recently became operational.

The Dr. H. P. Heineken Prize is
awarded once every three years to a
scientist who has performed
pioneering work in the fields of
biochemistry or biophysics. The
prize is named after the father of
our present Chairman of the Board
of Managing Directors, Mr. A.H.
Heineken. Dr. Henri Pierre
Heineken was a doctor of
chemistry and an enthusiastic
scientist. The prize was awarded for
the first time in 1964. The Heineken
Foundation, established in 1963 to
promote science and culture,
confers the prize, which consists of
46,800 in cash as well as a crystal
bearing a miniature replica of the
microscope invented by Antoni
van Leeuwenhoek (1632-1723),
the Dutchman who was the father
of microbiology. This year was the
eighth time that the Dr. H.P.
Heineken Prize has been awarded.
TWO WINNERS OF
1985 DR. H.P. HEINEKEN
PRIZE I
Dr. Julesz, Hungarian by birth, is the
head of research into visual perception
at Bell Laboratories in Murray Hill,
USA. He has succeeded in designing
methods for the testing of eye
abnormalities. His methods are used in
many clinics.
Each eye forms a slightly different
image from the other and the
combination of these two different
images allows us to see things in depth
With the aid of a computer Dr. Julesz
designed pictures which consist of a
collection of black and white squares
positioned "at random". In one of
these pictures he placed a number of
sections which together form a
particular shape, for instance a
rectangle, pointing in one direction. If
such a picture is then viewed through a
stereoscope, the shape appears to
move towards the viewer as if there is
depth in the picture. A picture like this
is called a stereogram. Using this
stereographic technique,
abnormalities in the stereoscopic
vision of the eyes can be identified with
great precision.
Professor Dr. Werner Reichardt is
director of the Max Planck Institute for
Biological Cybernetics in Tubingen,
West Germany.
Prof. Reichardt's main achievements
lie in the field of the visual processing
of information by the brain, especially
as regards the perception of
movement. He used ordinary house-
flies in his research. As everyone
knows, those are insects with good
eyesight. In his laboratory Reichardt
constructed a sophisticated "home
trainer" for the house fly. He
suspended the fly on a thin wire inside a
cylinder. Then all sorts of pictures were
projected on to the sides of the
cylinder. Via the tiny wire the fly's flight
movements were recorded, so that it
was possible to make various
measurements. Thanks to these
investigations a lot has now become
known about what happens in the
brain when the eye perceives motion.

In May this year the president of the Kirin Brewery Co. Ltd.,
Mr. Motoyama, paid a visit to Heineken. Mr. Motoyama was
accompanied by his wife and by Mr. Okada, a senior staffmember of Kirin
The visiting party was welcomed by Mr. Heineken at our brewery in
Zoeterwoude (Holland). Since 1984 Kirin has been brewing Heineken
beer under licence for sale on the Japanese market.
By pressing a button, which
was the signal for lots of
noise from many hooters
and bells, the Dutch Minister of
Economic Affairs, Mr. G.M.V. van
Aardenne, performed the official
opening of new heat/power co-
generating plant. This new power
plant will enable the brewery to cover
its own electricity and steam
requirements. Nationally, it will mean
a saving óf some 11 million cubic
metres of gas on an annual basis.
Three gas turbines form the heart of
the power plant. These turbines drive
generators which produce electricity.
Then the hot exhaust gases from the
turbines are used to raise steam for the
brewery. Brewing kettles,
bottlewashing lines and pasteurisation
units are the brewery's heaviest heat
consumers. Coupling the generation of
power (electricity) with the generation
of heat (steam) means that consider
ably less energy is wasted compared to
the former situation when electricity
was taken from the public grid.
In conventional public power stations
the steam that has been used in the
turbine to generate electricity must
first be cooled down (condensed) until
it turns into water again. After that, it
can be fed back to the boiler in which
steam is raised. During that
condensation process a lot of heat is
given off and carried away in the
cooling water. This is accompanied by a
substantial loss of energy. The energy-
efficiency ratio for that form of power
generation is at most 40%In a
combined heat and power plant this
ratio is considerably higher (about
78%). The heat/power co-generation
plant in Zoeterwoude can supply 11
megawatts of electricity and 55 tonnes
of steam an hour.
The project was achieved via cooper
ation between Heineken and Shell.
For the purpose of this cooperation a
joint venture was set up in which both
partners have a 50% share. The
agreement was signed in 1983 and
construction of the plant started in
1984. The total project involves capital
expenditure of over 5 million.
