Abstract
It is now known with certainty that the concentration of greenhouse
effect gases in the atmosphere causes global warming. There are six main
greenhouse gases, including, in particular, carbon dioxide. Greenhouse
gas emissions are projected to significantly increase unless mitigating
policies are implemented. In 1997, the Shimadzu Co. began to develop a
newer technology for carbon dioxide fixation. This technology was
directly aimed at reducing carbon dioxide gas emissions. The Shimadzu
Co. then developed a model in which bio-gas (a mixture of methane and
carbon dioxide) was changed into stable solid carbon and water by using
catalytic reactions. Bio-gas is produced by the anaerobic digestion of
biomass. Therefore, it also involves biomass recycling. Since 1998, the
Shimadzu Co. and Sapporo Breweries, Ltd. have conducted a laboratory-scale
carbon dioxide fixation experiment in the brewery. In the experiment, the
bio-gas was obtained from the brewery wastes. We found that carbon dioxide
fixation technology can be applicable for practical use. A part of this
work was carried out in cooperation with the Research Institute of
Innovative Technology for the Earth (Kyoto, Japan).

S�ntesis
Ahora se sabe con
certeza que la concentraci�n de gases que resultan del efecto invernadero
en la atm�sfera afectan el calentamiento global. Existen tres gases
principales causados por el efecto invernadero, siendo el principal el gas
carb�nico. La emisi�n de gases tipo invernadero aumentar�n
significativamente a menos que se adopten pol�ticas para frenarlo. La
Shimadzu Co. comenz� en 1997 a desarrollar una tecnolog�a para la
fijaci�n de gas carb�nico, con el prop�sito de reducir la liberaci�n
de gas carb�nico a la atm�sfera. Luego desarroll� un modelo en el
cual bio-gas (una mezcla de metano y gas carb�nico) fue transformado por
una reacci�n catal�tica en un carb�n s�lido estable y agua. El
bio-gas es producido por la digesti�n anaer�bica de biomasa, por lo que
tiene que ver con el reciclaje de biomasa. La Shimadzu Co. y Sapporo
Breweries, Ltd. han conducido, desde 1998, un experimento en escala de
laboratorio para la fijaci�n de gas carb�nico, utilizando el bio-gas
obtenido de los efluentes cerveceros. Se determin� que la tecnolog�a de
fijaci�n de gas carb�nico tiene aplicaciones pr�cticas. Una parte del
trabajo se realiz� con la cooperaci�n de la Research Institute of
Innovative Technology for the Earth (Kyoto, Jap�n).
