Environmental Load Reduction

Santen seeks to reduce environmental impact by taking measures to deal with the depletion of natural resources by converting to renewable raw materials and resources, contributing to solving water resource problems by efficiently using water resources in business activities and purifying wastewater, and preventing environmental pollution.

Detailed information on reducing environmental impact is disclosed in the Environmental Data Book.

Waste Reduction

In Japan, Santen promote the 3R initiatives of “Reducing” the production of waste, “Reusing” packaging and stationery used during the distribution process, and “Recycling” waste by sorting, at each operational site. Furthermore, we ensure that our waste is properly treated at our outsourced waste disposal service provider by confirming the waste policy, and the form of management of the waste treatment, and by making regular visits to the service provider. Before concluding an agreement with a new outsourced waste disposal service provider, we visit the outsourced service provider and check that appropriate waste treatment is being conducted. The final disposal rate in FY2020 was 0.01%. We have achieved the medium-term target of reducing the final disposal rate to 0.01% or less by FY2020.

Santen’s final disposal rate as a Group in FY2020 was 0.3%, We worked to reduce waste even production volume expanded, and achieved the medium-term target of reducing the final disposal rate of the entire group to 2.1% or less, which is the same level of FY2017, by FY2020.

Conservation of Water Resources

While no Santen plants or laboratories are located in areas under water stress,(*)we view water as a precious resource and are striving to reduce our environmental impact by restricting water consumption and other means. Our water consumption per unit of revenue in FY2020 was 2.2 thousand m3 per billion yen, constituting of 8% reduction from FY2015. We worked to curb water usage even though production volume expanded, and achieved the medium-term target of reducing the basic unit of sales revenue for water usage by FY2020 to less than the level of FY2017 of 0.24 thousand m3 per billion yen.

  • Being under water stress: Situation where the annual amount of water available for use per person is below 1,700 m3, causing people to suffer water-related inconveniences in their everyday lives

Appropriate Control of Chemical Substances

Santen seeks to provide appropriate control of chemical substances at every operational site that handles chemical substances.

In Japan, based on the Law concerning Pollutant Release and Transfer Register (hereinafter, “PRTR”) and the Industrial Safety and Health Act. Among the 462 Type 1 Specified Chemical Substances according to PRTR, the substances of which we handled more than 1 kg per year in FY2020 were 27 substances with a total mass of 3,062kg, including acetonitrile, 1,857kg, boron and its compounds, 611kg, and xylene, 391kg. Because more than one ton of acetonitrile per year was handled at a single operational site, we registered the amount of release into the air as well as the amount of transfer to the outside of the operational site according to the PRTR.

Furthermore, we introduced a “system for controlling chemical substances” to provide centralized control of the amount released and stored and the location of storage, as well as to appropriately purchase and use chemical substances. In order to reduce the release of chemical substances into the air as well as to decrease the impact on the environment, we installed an instrument to recover organic solvents, and ensure that the performance of the instrument is maintained through inspection and maintenance of the instrument.

Prevention of Environmental Pollution

Santen regularly measures and analyzes a variety of indices at each operational site, including air pollution, water contamination and noise levels, in order to appropriately control and identify pollution levels according to the regulatory standards stipulated in laws and local regulations.

We also compile procedures to prevent the leakage of pollution and install equipment that prevents wastewater leaked from the storage container from flowing into the general discharge channel outside the plant, and practice the operation thereof. We establish the system to prevent impact on the environment and the neighborhood.

Hazardous Waste trend

According to the laws and regulations of various countries, we have defined as “Hazardous Wastes,” specially managed industrial wastes in Japan and hazardous wastes in China, and disclose the results for FY2020.

The Hazardous waste emissions in FY2020 were 164 tons.

Forest Conservation Activities

Because appropriate forest conservation contributes to not only facilitating the absorption of CO2 but also maintaining the rich natural environment and headwater conservation capacity, leading to the protection of biodiversity, Santen engages in forest conservation activities.

Activities of Noto Plant

Noto Plant supports the Environmental Education Project to conserve nature at Mt.Hodatsu, organized by the board of education of Hodatsushimizu Town, the local government of the area where it is located.

Activities of Shiga Product Supply Center

Santen employees participate in events held by a Shiga Prefecture-based NPO to offer practical training on the management and use of satoyama (village forest) forests and other matters. However, it was not implemented because of the COVID-19 infections in FY2020.

Employees are taking training on the use of satoyama forests.

Local Environmental Clean-up Activities

To contribute to the cleaning up and beautification of local environments, Santen’s offices, laboratories and plants, including the Noto Plant, the Shiga Product Supply Center and the Shimoshinjo Office (Osaka Office), conduct clean-up activities in collaboration with local governments and regional organizations. However, we have reduced the scale of activities due to the COVID-19 infections in FY2020.

Employees are participating in clean-up activities.
