6 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 power plant Heineken and Shell 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.

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. Minister van Aardenne presses the button to open the heat!power co-generating plant. Right: Mr. A. A.
