Environmental Protection Activities

Cooperation with Suppliers and Group Companies

Aisin AW pursues its environmental conservation activities based on an Environmental Management Program (EMS) and with key emphasis on the three imperatives of complying with laws, preventing accidents, and improving performance.

AW's approach to environmental conservation

Management of Chemicals

While chemical substances provide numerous conveniences in our corporate activities, they also account for some of the environmental impacts of our operations. We strive to minimize the environmental impacts of chemical substances while taking advantage of the benefits they offer.

Preliminary Chemical Evaluation and Management Systems: Example Using Greases and Chemical Substances

Sections of the company that plan to use new greases or chemical substances apply in advance to do so after taking such steps as checking applicable laws based on the relevant material safety datasheet (MSDS) and testing whether the new material is amenable to removal from wastewater streams during treatment. Next, the Environmental Management Section conducts a comprehensive evaluation including the material's impact on the human body and the environment. In this way, only approved greases and chemical substance are used in the company.

Dealing with Soil and Groundwater Problems

At the end of 1993, Aisin AW completely stopped using organic chlorine solvents that pollute soil and groundwater, such as trichloroethylene and 1.1.1-trichloroethane. Since then we have conducted soil and groundwater investigations at all our plants where these solvents had been used. We then examined the most effective solutions for rehabilitating our head plant after pollution was detected there, and implemented measures to repair the environmental damage.

Preventing underground seepage

Aisin AW has been installing linings in catch basins and relay tanks consisting of underground pits in an effort to prevent soil pollution caused by underground seepage of oils and fats. We completed these efforts for all 88 existing facilities in May 2008. New facilities are required to incorporate these specifications from the design stage.
Starting in fiscal 2011, we will focus on making buried plumbing visible under the three-year plan.

Air Quality Efforts

To reduce air pollution, Aisin AW is promoting measures such as upgrading facilities to use state-of-the-art technology, eliminating the use of toxic materials, and making use of cleaner fuels.

Reducing Toxic Gas Emissions

To prevent the generation of toxic gases from our incinerators, we have implemented emissions controls. Through careful combustion control and exhaust gas treatment technology we have eliminated harmful gases such as hydrogen chloride gas and dioxin, We also conduct continuous measuring and monitoring to ensure compliance with emission standards.

Conserving Water Quality

In addition to batch processing of oil-contaminated wastewater, production process wastewater, and domestic wastewater discharged by company facilities at a general water treatment plant, AW is working to prevent water pollution by installing equipment for separating oil from rainwater runoff at production plants. The company also recycles some processed water, circulating it for use in industrial processes in an effort to conserve water resources.

Treated wastewater recycling and abnormal wastewater/raw water return system

  • 1. Treated water is recycled and used in industrial processes, to water grass and plants, etc.
  • 2. When abnormal wastewater is detected, the system automatically stops all discharge immediately and returns the abnormal.

Rainwater treatment system

AW collects all rainwater runoff at its production plants for storage in regulating reservoirs after all oil content has been separated out. The system is designed to prevent oil from flowing into surrounding rivers.

Biotope of Okazaki East Plant

The biotope at Okazaki East Plant is home to a variety of local animal and plant life clustered around a creek carrying water discharged from the plant's wastewater treatment facility. The plant has released Japanese killifish and dark chub, species that live in downstream rivers, into the creek and continues to confirm that the newcomers are not having a harmful effect on the host ecosystem.

Noise Pollution

Aisin AW's noise pollution measures focus primarily on prevention. Our first priority is to address the source of noise, so we design all our facilities and machinery with low-noise specifications from the planning stage. We are also working to reduce the noise level in work areas by installing soundproofing materials and structures on equipment and machinery as necessary. Finally, we regularly take readings of noise levels at the boundaries of plant premises to ensure that noise levels meet environmental regulations.

Noise Pollution Countermeasure

Efforts to combat noise pollution include mechanisms to ensure not only evaluations at the planning stage for equipment and facilities whose impact may be felt at the boundaries of plant premises but also reliable re-evaluations when systems are updated or otherwise modified.

  • Noise pollution countermeasures implemented when cleaning towers were updated
  • Noise pollution countermeasures at a cogeneration facility

Greening Initiatives

Creating Landscapes of Green and Flowers

Based on the four basic concepts listed above, Aisin AW develops attractive parks and gardens and opens them to the local community; it holds a flower festival with the participation of all employees; it is working to protect natural forest on the company's land; and it is implementing a "five-year greening plan" at all of its plants. In acknowledgement of these efforts we received the following awards:
To promote Harmony and goodwill with local residents To create safe, comfortable and healthy workplaces for employees To promote communication between all employees To improve the company's image

Minister for International Trade and Industry Award for the Greening of Industrial Facilities

Chief of Agricultural Production Bureau Award for the National Flower Town Creation Contest

Flower Festival (with participation by all employees)

Contact with Nature (Installation of a Break Area in a "Green" Setting)

We added new break areas as one way to increase employee satisfaction. Designed to evoke parks and gardens so as to provide an environment that is conducive to employee relaxation, these areas incorporate trees and grass, exercise and health equipment, and other amenities.

Rooftop Gardening

Rooftop gardening at the Monozukuri Center (approximately 2,000 square meters) was recognized as Aichi Prefecture's first rooftop greenbelt in 2005. Rooftop gardening helps reduce air conditioning energy use.

Seasonal Flowers

Plants such as cherries and azaleas in the spring and pansies in the fall enable employees and visitors alike enjoy the changing of the seasons.

Relaxing by the Water (developing a park-like biotope)

We built a walking path and a grass plaza near a rainwater regulation pond at the Head Office Plant to serve as a place for improving communication among employees. We planted flowers and fruit trees so that employees could experience the passing of the seasons in the setting of a park-like biotope.

【View from the southern side of the third floor】
A grassy relaxation plaza lies in the center, and a walking path rings the pond (about 250 meters in length).

【View toward the west from the grass plaza】
Visitors can see the pond in its entirety as well as Route 23. Benches in the plaza provide seating for about 30 people.
