About the portable automatic water sampling device.

Real-time VFA monitoring device to maximize the efficiency of methane fermentation in anaerobic digestion.

The online VFA meter EZ7200 series is a high-performance online titration device designed for monitoring wet anaerobic digestion tanks. It proposes a new management method for medium to large-scale anaerobic digestion processes. In biomass power generation, industrial wastewater, and sewage treatment, the anaerobic treatment of wastewater and sludge in fermentation tanks involves the breakdown of very complex organic carbon compounds, which presents challenges. Real-time measurement of VFA (volatile fatty acids) is effective for stabilizing the methane fermentation tank in anaerobic treatment. Relying solely on pH measurement and sampling can make it difficult to monitor the conditions inside the fermentation tank, depending on the timing. The ideal pH value inside the fermentation tank is said to be between 6.5 and 7.5, but measuring pH alone is not sufficient; adequate buffering capacity [total alkalinity TAC (also referred to simply as alkalinity)] is necessary to compensate for changes in acid concentration. By continuously monitoring VFA, which are intermediate substances during methane fermentation, it contributes to maintaining a more stable fermentation tank and maximizing gas production. By conducting online measurements at 10-15 minute intervals, it becomes possible to anticipate various events within the digestion tank in advance.

We would like to inform you that our company has recorded a special loss (executive retirement benefits) for the first half of the fiscal year ending December 2025, as detailed below. Furthermore, the payment of executive retirement benefits was approved at the "51st Annual General Meeting of Shareholders" held on March 28, 2025. 1. Recording of Special Loss In recognition of the long-standing contributions of one retiring director, we have recorded a special loss of 14,045 thousand yen as executive retirement benefits. 2. Impact on Performance The impact of this matter on the performance forecast for the fiscal year ending December 2025 is minimal. End.

We will disclose the interim financial results for the fiscal period ending December 2025.

As part of the "Hometown Ibara Future Creation Human Resource Development Project," we welcomed local elementary and middle school students to the special summer program "Ibara Job Exploration Tour 2025," a collaboration between the Ibara City Chamber of Commerce and the Corporate Branding Committee. We conducted a presentation that clearly and enjoyably introduced how our technology supports society, allowing the children to learn about the appeal of manufacturing and the significance of working while interacting with actual devices and products. Through this initiative, we hope to deepen our connection with the community and nurture the curiosity of the children who will carry the future. We sincerely thank everyone who participated, as well as all those involved in planning and organizing the event.
