Stance and target

Why is "Effluents and Waste" a critical issue to be addressed?
Explanation of the reason and background

We believe that minimizing the impact of our business activities in Japan and overseas on the environment will lead to sustainable operations. Accordingly, we believe that it is important for effluents and waste to be minimized as much as possible in a form with a low environmental impact.

Vision (attainment goal) / target

Mid-term targets are set for water use in Japan and overseas.
Based on these targets and after confirming water risks and the status of wastewater, we will improve recycled water use and ultimately aim for a closed system.
We will work to achieve a reduction of 1% in waste materials per unit of waste, and aim for the attainment and maintenance of 100% recycling*1. We will then aim to achieve total zero-emissions*2 at all production bases by FY 2017.
Specially managed industrial wastes such as PCB, asbestos, and chlorofluorocarbons will be appropriately processed in accordance with laws and regulations.

*1 100% recycling: Achieve zero final disposal (= direct landfilled amount + incineration disposal amount resulting in ineffective use)

*2 Total zero-emissions: Make the direct landfilled amount.

Measures for vision achievement

  • We will introduce water recycling facilities, increase recycled water use, and reduce the volume of water discharge.
  • Even for business locations that have been established in accordance with law, we will look for and select industrial waste disposal contractors that do not conduct landfilling, and contract recycling processing.
  • The processing of PCB-containing devices owned will be conducted within the legal deadline.

Review of FY 2014 activities

At overseas production bases in areas with high water risks (Thailand and India), closed systems have been introduced at the time of plant construction, and there is minimal water uptake and no water discharge.

Generated amount of waste material at Group companies in Japan and overseas

The generated amount of waste material at all Group production bases in Japan and overseas during FY 2014 increased by 2.0% year-on-year to 31,039 tons.
We conduct recycling and activities aimed at achieving total zero emissions at all production bases in Japan and overseas. In FY 2014, zero emissions were achieved at production bases in Russia and maintained subsequently.
We are conducting activities aimed at the target of total zero emissions by FY 2017 at production bases overseas (North America).

Storage and management of PCB wastes

Used PCB-containing devices are properly stored and processed based on laws and regulations. During FY 2014, 66 PCB-containing devices (26 tons) were processed. We will continue to properly store and gradually process PCB-containing devices.

Case introduction

At the Onomichi Plant, we improved and strengthened water filtration capabilities, worked to stabilize water quality, and succeeded in significantly improving the period of possible repeated use.

Generated amount of waste material at production bases in Japan

The generated amount of waste materials in FY 2014 resulted in 17,226 tons, a 2.1% decrease year-on-year, and we were able to improve the unit base of the generated amount of waste materials (per net sales) by 6.5% compared to the previous year.

The processing flow for waste materials at production bases in Japan during FY 2014 is as follows.

In order to prevent improper disposal such as illegal dumping, local audits are conducted on processing contractors every year. A total of 85 audits were conducted FY 2014, and it was confirmed that all contractors conducted proper disposal.

Issues and future improvement measures

  • Selection of industrial waste disposal contractors that don't conduct landfilling at overseas production bases
  • Development of low water use facilities, closed system reviews and investments
  • Formulation of disposal plans for devices containing low concentrations of PCB that are currently in use
