NGK ISSUES ENVIRONMENTAL REPORT 1999

NGK Insulators, Ltd. (President: Masaharu Shibata, Head Office: Nagoya, Japan) has issued its "Environmental Report 1999" which covers NGK's commitment to environmental conservation.

NGK's goal is to continuously be an excellent company based on global standards and we believe that NGK is responsible for making a first class effort to solve environmental problems. NGK's "Environmental Protection Committee" was established in 1972 and has taken a far-ranging approach to environmental issues. In 1996, we adopted NGK's core policy concerning the environment. Specific action guidelines and promotion systems have been formulated to contribute to the resolution of global environmental issues through our work in the "Triple E" areas: Ecology, Energy and Electronics. In 1999, three of our major production bases simultaneously won recognition for the global standard of their environmental management system; achieving ISO 14001 certification.

NGK applied its honeycomb forming technology to the development of a honeycomb monolith-type Diesel Particulate Filter (DPF) made from SiC, and also succeeded in controlling costs. Moreover, we developed a new ceramic material to achieve further cost cutting. Its thermal expansion is as small as cordierite DPF and thermal resistance is excellent. It is therefore possible for our new DPF to accumulate and combust 2-3 times the volume of particulates than conventional filters. This is expected to make DPF system design easier. In June, NGK will start supplying samples made from the two newly developed materials, and maintain and strengthen our mass production/supply system. It is believed that the expensive SiC will be used in DPFs in the short term, but in the middle and long term, tighter regulations will make sulfur content of diesel fuel lower. Our newly developed ceramic material and cordierite will then be used as the principal materials for DPFs.

Our "Environmental Report 1999" is the revised edition of our first Environmental Report 1998 issued in March, 1999 and adds the latest data from 1998. This new report introduces NGK's specific efforts to solve critical environmental problems such as the reduction of CO2 and industrial wastes, and our environmental preservation activities which aim for "zero emissions".

This Environmental Report contains 16 A4-sized pages made of 100% recycled paper from used milk cartons. Furthermore, the report was printed using soy ink, which reduces petroleum solvents and emissions of the volatile organic compounds (VOCs) generated during printing. For these environmental considerations, this Environmental Report was awarded the "Eco Mark" by the Japan Environment Association. Our "Environmental Report" will be issued annually and put on our Internet home page at: http://www.ngk.co.jp.
