Abstract
Industrial cleaning technology is one of the Monodzukuri basic technologies, and at the same time, it is an essential technological element to apply to other many Monodzukuri basic technologies. About twenty years ago, in order to protect the ozone layer in the stratosphere, we have coped with the phase-out of the ozone depleting substances in the industrial cleaning processes by the global scale team work. That success story is receiving more attention again as useful information to prevent the global warming. As emission restriction of alternative fluorocarbons, one of global warming gases, is under investigation by the Council of Industrial Structure in the Ministry of Economy, Trade and Industry, this paper intends to inspect the progress of the activities of the ozone layer protection in one field of monodzukuri.
