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.

Voice from the Person in Charge

Aiming to be an environmental top player, AISIN is working to more effectively utilize its water resources. Our efforts in wastewater treatment are particularly noteworthy in that we have realized 20% recycling for cogeneration systems at the Kariya Plant. Currently, we are taking active measures, with Aisin Hokkaido installing the latest equipment directed toward realizing a recycling rate of 90%

Kariya Plant Wastewater Treatment Facility

To promote the introduction of wastewater treatment facilities, AISIN installed a new circulating system that meets its stringent environmental standards and employs the treated water in the plant's cogeneration system (20% reduction).

Groundwater Purification Measures

AISIN actively promotes groundwater purification measures in an effort to achieve a value below the environmental standard without further delay.
