Pollutant Release and Transfer Registers (PRTR) Targeting for complete elimination of methylene chloride Making Doubly Sure of Compliance with PRTR Since 1998, TDK has voluntarily participated in a survey on Pollutant Release and Transfer Registers (PRTR) conducted under the auspices of the Federation of Economic Organizations. We have held company-wide explanatory sessions and taken other steps to make doubly sure we will be in compliance with Japan’s Pollutant Release and Transfer Registers Law, which was enacted in July 1997 and is scheduled to take effect in April 2001. Figures on the respective amounts of air, water, and soil emissions containing substances addressed by the PRTR Law, along with the quantities of constituent waste substances, are shown in the table below. We are committed to the goal of reducing the overall volume of our emissions of chemical substances by 20%, relative to 1997 levels, by March 2006. The figures for fiscal 1999 show a 6.1% reduction, as well as a 34.6% reduction in the use of methylene chloride, a substance used to clean electronic components. Our goal is to completely eliminate methylene chloride emissions by March 2001, and to this end we are proceeding with efforts to come up with techniques that are not dependent on detergents and are exploring the possibilities for using alternatives.
