Oil spillage accident and response (Aisin Seiki)

There was an accident in which fuel containers loaded on a construction contractor vehicle toppled, spilling light oil into a river.

Upon discovery, Aisin Seiki contacted the relevant authorities and began clearing the oil slick. Although the effect on the environment was minimal, the company formulated measures to prevent recurrence such as notifying all of its construction contractors of the precautions required when transporting fuel containers.

Expansion of the E-Volante system (Aisin Seiki)

Aisin Seiki is working on expanding its water quality management system known as E-Volante. Using this system, the Company is integrating management of waste water data, such as pH values, measured at each of its business bases and communicating information to those bases for risk minimization. In FY2011, the Company implemented the system at two plants and one proving ground.

Regular monitoring of groundwater (Aisin Keikinzoku)

Aisin Keikinzoku installed observation wells at five locations within the premises of its main plant, through which groundwater is regularly monitored so that it can promptly respond in the event of any contamination.

Introducing a System to Purify and Recycle Industrial Effluents (Aisin Hokkaido)

One of AISIN's basic concepts is the “pursuit of zero emissions” in aiming to operate ecological plants. Aisin Hokkaido which was established in February 2006 installed the latest equipment to purify plant wastewater and recycle 90% of it as industrial water. This represents Japan's first die cast production plant to make such efforts.

Among the benefits that can be anticipated from this equipment are

1. Reducing the amount of waste-water to enable a reduction of environmental load
2. By purifying plant wastewater to a quality that exceeds that of industrial water, accumulation of scale inside pipes is prevented, which also leads to energy savings, as less power is required without pressure loss arising from pipe blockage.

We are working towards the goal of 90% recycling of plant wastewater by managing the operation of an economical and sustainable system.
