Environmental activity plan S-TEC:Sanyo Tactics for Eco Challenge

We developed the environmental activity plan S-TEC mainly focusing on energy saving, reduction of release of chemical substances, and measures against waste, and since fiscal 2000, we have been promoting it as a company-wide activity. In the S-TEC for the period from fiscal 2018 to fiscal 2020, we have been engaging in the activity with its name changed to Global S-TEC Level 2.

Environmental load reduction activity

Energy saving

In 2005, when the Kyoto Protocol came into effect, we established the Kyoto Protocol Activities Policy and formed a working group (WG) to combat global warming issues with our domestic offices. Since then, we have been working on issues for the improvement of energy use efficiency, improvement of production process, and fuel conversion.

As a global goal, we aim to reduce the unit energy consumption per production amount by 5.9% from the fiscal 2014 level.

In 2018 onwards, the unit energy consumption has been significantly worsened mainly due to a reduction in the domestic production amount and increase in the production amount of products that require more energy in manufacturing.



Reduction of greenhouse effect gas emission

The Global S-TEC Level 2 sets the domestic CO2 emission goal as 190,000 tons or less for fiscal 2020 and 160,000 tons or less for fiscal 2030. The goal for fiscal 2030 corresponds to a decrease by 25.4% from the fiscal 2005 level, which is the same decrease rate as the goal of the Japanese government.


The CO2 emissions from the domestic offices in fiscal 2019 significantly decreased to 176,000 tons (-8.3% in comparison with the previous year) due to the decrease in the production amount (-9% in comparison with the previous year).


In overseas affiliates, as the production amount is expected to increase year by year, the goals are set by using the unit CO2 emissions per production amount as an index. In fiscal 2019, the overseas production amount increased, CO2 emissions decreased by 3.2% compared with the previous year mainly due to the improvement of unit CO2 emissions from SDN and the stabilization of production in SDPM, which started operation in fiscal 2018, but the goal could not be achieved.



Preservation of water resources

In the Global S-TEC Level 2, from the viewpoint of water resource protection, unit service water use per production amount is included in the indexes, and the goal is set to decrease by 6.8% from the fiscal 2014 level.


Water resource measure WGs are established in domestic offices, progress management is conducted with the reduction target items, such as repetitive use or recycled use of service water in the production process and reuse of steam drains, listed in the form of slip, and their information is shared by our group for the promotion of the activity.


In fiscal 2019, the unit service water use worsened from the decrease in production amount and the increase in the production rate of products that require larger amounts of service water for manufacturing.



Resource saving/reduction of wastes

To effectively use the resources, we are engaged in the 3R (reduce, reuse, recycle) activity.


While the amount of domestically generated waste in 2007 was 72,000 tons, it decreased to 46,000 tons in 2014 because of the waste reduction challenge. The Global S-TEC Level 2 sets the goal of total generated waste amount at home and abroad to 50,000 tons or less and the goal of landfill disposal amount to 10 tons or less, although the overseas production amount is expected to increase.


The generated waste in fiscal 2019 showed a decrease in association with the decrease in the domestic production amount, which accounted for the great majority of the total generated waste amount.



Reduction of release of chemical substance

We have been conducting a voluntary activity to understand the amount of chemical substances released and transferred into the environment and to promote a reduction in the release of chemical substances by determining priorities.


In fiscal 2019, the amount of volatile organic compounds (VOCs) released into the atmosphere increased by 18% to 89 tons compared with the previous year, exceeding the goal value. This is because of the three months’ stoppage of the VOC treatment equipment in the Kashima Factory due to a defect.


In the Nagoya Factory, the release of propylene oxide is expected to decrease to the goal value or below from the improvement in treatment, but for the purpose of further reductions in the release amount, we will continue to discuss the introduction of VOC treatment equipment.

The substances subject to the PRTR Law are reviewed by the national government, and the law is expected to be significantly revised in the near future. In order to promptly respond to the revision, we have started the preparation for it.



Chemical substance management

In accordance with our chemical substance management rule, the handled chemical substances are classified into prohibited substances, restricted substances, and substances to be appropriately managed, and we manage the handling of the chemical substances during production and inclusion in products to assure safety. We have completely abolished the handling of the substances that had been prohibited substances according to the hazardous substance reduction program implemented in the past, such as lead compounds and dichloromethane.


There are a wide variety of chemical substance management laws and regulations, which include the Act on the Regulation of Manufacture and Evaluation of Chemical Substances, Industrial Safety and Health Act, PRTR Law, and Poisonous and Deleterious Substances Control Act. In our business activity, the Product Evaluation Department undertakes control in accordance with these laws and regulations in terms of products and the Environmental and Safety Administration Department undertakes the control in terms of production.



Pollution prevention

In order to prevent air and water pollution, we observe the standard values stipulated in the relevant laws and regulations through appropriate maintenance and management of equipment, periodic inspections, and other measures and try to suppress the release of these contaminants. Concerning soil and groundwater pollution, we have been continuously conducting voluntary inspection on our premises in such opportunities as construction, and no special problems have arisen.


In fiscal 2019, we received a complaint about noise from neighborhood residents. We made apologized and implemented countermeasures. There have been no violations of laws, regulations, or administrative direction nor any lawsuits related to the environment.
