Toward a resource recycling society
Achieving a sustainable society is a goal shared around the world. Tackling environmental problems such as global warming and resource depletion will help achieve this goal, and corporations are increasingly expected to lead those efforts.
The Nippon Soda Group utilizes the water treatment technology, resource recycling technology, heavy metal removal technology, and other technologies developed over its long history, to come up with various environmental solutions and develop business. For sustainable plant protection, we are also contributing to the protection of the pine forests that are a feature of Japan’s natural heritage.
SDGs
Materiality
Contributing to the environmentally sound recycling of resources through chemistry (technological expertise)
-
01
Steady supply of water resources
-
02
Reduction of environmental burden caused by waste
KPI
① Volume of Water Contributed
Volume of water that can be treated with solid chlorine agents sold by Nippon Soda in FY 2025/3: 3.3 million metric tons
② Current Initiatives
In the field of waste treatment, at Nippon Soda we have developed and supply HIDION, a heavy metal fixing agent for fly ash treatment at waste incineration plants. Approximately 31.2 million metric tons1 of waste is treated annually in Japan, and approximately 1.20 million metric tons2 of fly ash is generated through the incineration process. The high quantities of lead and other heavy metals in this fly ash can pollute the environment when released as metal ions, and so by law, fly ash must undergo solubilization treatment.
In addition to demonstrating excellent heavy metal fixing performance in this process, HIDION is highly safe to handle, and has therefore received wide acclaim and been used by many incineration plants across Japan for more than twenty years.

① Current Initiatives:
Contribution to Pine Forest Protection and Contribution to Local Communities
Results in FY 2025/3
- 1. Training of forestry workers: We hosted a training session for forestry workers on the mechanism of pine wilt and measures to control pine wilt in the field at a forestry training facility in western Japan. We dispatched one employee on the day as an instructor to provide technical advice and answer questions from participants. (Participants: Approx. 15)
- 2. Technical education (pine): We participated in a training seminar on how to control pine wilt at the request of prefectures in the Chubu region. We dispatched two employees on the day as instructors to provide them with basic technical information on controlling pine wilt. (Participants: Approx. 30)
- 3. Technical education (cherry): We dispatched two employees to provide technical information at a booth at a symposium hosted by prefectures in the Kansai region on the red-necked longhorn beetle. This region has seen a rapid increase in damage from the red-necked longhorn beetle in recent years. We received many questions from participants and gave advice on how to better control this pest. (Participants: Approx. 100)
