Achieving Drastic Reductions in Environmental Load Emission Volume Per Unit of Sales in Our Global Production Activities


As we engage in the manufacturing activities of a wide range of products and parts such as automotive parts and life related products, fossil fuels, industrial water and chemicals are consumed. However, we are focusing our efforts on reducing substances of environmental concern and adhering to the regulations on wastewater and air pollution by establishing and following the Aisin Environmental Standard, our own stringent standard.

Soil and Groundwater Contamination Countermeasures at the Nishio Plant

In June 2006, an abnormal discharge of water was found when renovating facilities at Aisin Seiki's Nishio Plant. When the soil was analyzed and surveyed, it was discovered that levels of hexavalent chromium and cyanide compounds in part of the soil exceeded environmental standards.

Aisin Seiki acted in accordance with guidance from Aichi Prefecture and other relevant authorities to swiftly implement purification measures after a more detailed survey of the site. We also offered briefings and 2,000 liters of drinking water to local residents until safety could be confirmed. After a thorough survey, it was confirmed the well water was not contaminated.

Regarding our facilities, in addition to purification of the contaminated soil, we quickly took preventive measures such as increasing the number of pumping wells in order to reinforce purification treatment capabilities for contaminated groundwater.

Voice from the Person in Charge

While we caused worry among local residents, by April 2007 we were able to complete the implementation of countermeasures that included excavating contaminated soil, setting up 17 pumping wells and an additional 10 observation wells, as well as installing hexavalent chromium reduction devices. We will remain vigilant by continuing water treatment as well as periodic observations of groundwater to ensure that no contaminated water is leaked outside of our site.
