Environmental protection in the electronic and electrical industries

Global environment conservation in the electronic and electrical industries is discussed in this paper from three stand-points: the prevention of pollution and contamination, global environmental problems and the development of products contributing to environmental protection in the society. These can be summarized as follows: (i) to prevent pollution and contamination in manufacturing activities by way of environmental management and investment for improvements Hitachi has invested for the last twenty years; (ii) to establish an action program for environmental issues such as ozone-layer protection, global-warming prevention, industrial-waste reduction and products recycling; and (iii) to innovate and develop product technologies for the improvement of energy efficiency, contributing to the prevention of global warming.
