Reduction in Environmental Impact
We believe that we have a great corporate responsibility to reduce the environmental impact generated through business operations by addressing problems such as the various emissions from production activities and waste from products after use. We will, of course, continue to comply with environment-related laws and regulations, and at the same time, strive to accomplish voluntary targets by making efforts to use resources appropriately and conserve the natural environment.
Environmental Accounting
Hisamitsu Pharmaceutical compiles environmental accounting in reference to the Ministry of the Environment's “Environmental Accounting Guidelines” in order to quantitatively understand the investments and expenses related to environmental measures and their impact. In FY2023, for the purpose of reducing CO₂ emissions to prevent global warming and saving energy, we continued to promote new installation of solar panels, conversion of lighting fixtures to LED, the upgrade of air conditioners to energy-saving types, and power saving by improving the production operation ratio. Furthermore, we are increasing items with the smaller size of medicine bags, cases, and cardboard boxes for our products (Eco & Compact) and actively promoting the efficient use of resources.

Water Resources Management
Water resources are essential to business operations. We believe that it is integral to use finite water resources more effectively and reduce our environmental impact. We conserve water resources by properly managing both water usage and drainage volumes.


Response to water risks
In the Hisamitsu Pharmaceutical Group, an assessment of water stress, which is an indicator of water scarcity, was conducted on domestic and overseas production sites and R&D sites using WRI Aqueduct*, which is a tool for assessing the water risks around the world. As a result, we verified that there was no site that was evaluated as “High” or “Extremely high” in water stress. (As of August 2024)
There were also no sites where water restrictions or problem caused by water scarcity occured, so we recognize that there is no urgent water shortage risk.We will continue to assess water risks and work on the efficient use of water resources and the reduction of water usage.

Resource Recycling
We think that we should fully consider the effective use of limited resources in business management. We promote the reduction of resource input, waste recycling, and the use of renewable raw materials as well as striving for pollution alleviation and the proper management of chemicals.
Recycling
Production waste generated in the manufacturing process (including waste plastics) is used in thermal recycling as a heat source for a cement factory and other facilities. Ash generated after incineration is used as a resource to be mixed with cement and other materials, leading to a FY2023 recycling rate of 99.8%. Moreover, transportation materials after use are separated and collected by category and recycled as a raw material for recycled paper and as a cushioning material.

Management of Air Pollutants
SOx (sulfur oxides) and NOx (nitrogen oxides), which are emitted during the operation of boilers and private generators, cause air pollution. In order to reduce the emission of these pollutants, we are upgrading our equipment and gradually replacing our fuel from heavy oil with city gas. We comply with our self-imposed regulations, which are more stringent than the standards stipulated under the Air Pollution Control Act, and we confirm that the emission of these pollutants are below the levels set in our regulations.
*SOx and NOx values are totals for the Kyushu Head Office, Utsunomiya Factory, and Tsukuba Laboratories, which have large environmental impacts.

Management of Specified Chemical Substances
We at Hisamitsu Pharmaceutical ensure proper management of chemical substances in compliance with the PRTR Act.*1 Toluene is a chemical substance we are obliged to report to the authorities. In FY2023, we handled 3.4 t of toluene. We will continue to strive for appropriate use and management (storage and disposal*2) of the substance to reduce the environmental impact.
Although acetonitrile was exempted from the reporting obligation on April 1, 2023, we are switching to a new analytical method that does not use acetonitrile in order to reduce the amount used.
*1 PRTR Act: A law that requires the release amounts of certain chemical substances into the environment to be monitored and reported to the government
*2 Waste disposal:
・Waste liquid treatment
After use, the waste liquid is entrusted to a waste disposal contractor for proper disposal.
・Combustion treatment
Some manufacturing processes generate gases containing toluene. The gas is cooled and not collected as liquid waste but combusted using a gas combustion system (oxidative decomposition method).
Handling Volume of PRTR Substances( t )

---|---|---|---|---|
Toluene | Handling volume | 3.3 | 3.7 | 3.4 |
Emission into the air | 0.2 | 0.2 | 0.2 | |
Waste disposal | 3.1 | 3.5 | 3.2 | |
Acetonitrile | Handling volume | 4.3 | 3.3 | 3.0 |
Waste disposal | 4.3 | 3.3 | 3.0 |
Efforts to Go Paperless within the Company
We are making efforts to go paperless across the company by minimizing paper use for the reduction of environmental burden and using IT (digitization).In FY2023, the efforts resulted in reduction by around 69% in value terms and around 46% in terms of the number of sheets compared to FY2019, respectively.
We will continue to promote paperless operations in the future.
Emergency Drill
Simulating emergency situations, such as equipment damage and malfunction, operational errrors, and natural disasters, including earthquakes, typhoons, lightning, and flooding, we assess the types, scopes, and the severity levels of the impact that such emergencies are expected to have on the environment. Based on the assessment results, we formulate an action plan for contingencies to be handled with high priority and conduct emergency drills at least once a year. This enables us to prepare for minimizing the impact on the environment and our neighborhood.
By confirming through such drills how to respond in the initial phase and how to prevent the spread of damage, we are striving to improve our emergency response capability.

Internal Communication
●Commitments to Raising Employees’ Environmental Awareness
At Hisamitsu Pharmaceutical, we are raising the environmental awareness of employees, especially at the Kyushu Head Office and the Utsunomiya Factory, whose operations have a large environmental impact.While requiring the office and the factory to incorporate environmental training as part of their ISO14001 environmental targets, we also provide a wide variety of environmental training for our overseas business bases. In addition, we share environmental information through our inhouse website at appropriate timing so that the employees of our group companies worldwide will become more aware of environmental issues.
Commitment to Biodiversity
Some raw materials used for our products are derived from natural resources. In terms of sustainable procurement of raw materials, we think the conservation of ecosystems, including biodiversity is important.We are helping to conserve long-tail irises, designated as a 1A threatened species. Since 2015, we have been managing and nurturing this species’ seedlings from Kuboizumi-machi, Saga Prefecture on the premises of the Kyushu Head Office.
Environmental Impact Reduction at Overseas Factories
At our overseas factories, various measures are taken to reduce the use of water and the generation of waste as in the case of our domestic factories. They are working toward reducing environmental impact by raising the awareness of each of their employees of such impact.
