Conventional leachate treatment facilities cannot remove salinity. Currently, the concentration of chloride ions in the treated water is being discharged at around 10,000 ppm. While salt is essential for our bodies, excessive amounts can cause significant harm. The same is true in nature, especially for rice, which is sensitive to salinity, raising concerns about its impact. At Kyowa Chemical, we use a desalination device called "Super Saltless" to reduce the concentration of chloride ions in the treated water to below 500 ppm before discharge.

1,4-Dioxane is classified by the International Agency for Research on Cancer as Group 2B (possibly carcinogenic to humans), and discussions are currently underway in the Central Environmental Council's Water Environment Subcommittee to establish discharge standards. 1,4-Dioxane is poorly biodegradable and cannot be removed by biological treatments such as conventional activated sludge treatment, coagulation and sedimentation, or sand filtration. Additionally, adsorption treatment using activated carbon has a relatively low adsorption efficiency. Currently, the advanced oxidation process, which has a proven track record in the decomposition of dioxins, is the most effective treatment method.

This is an introduction to the Environmental Microbiology Research Institute of Kyouwa Chemical Co., Ltd. The Environmental Microbiology Research Institute aims to contribute to society through the development of scientific and technological solutions related to environmental issues, focusing on fundamental research on microorganisms that protect the environment and the development of technologies for utilizing these microorganisms. Although our institute is small in terms of facilities and the number of researchers, we are determined to achieve remarkable results, embodying the spirit of "even a tiny insect has a soul," and to play a part in solving environmental problems. We appreciate the support of all stakeholders. The decomposition of organic waste through high-temperature aerobic fermentation is a safe treatment method that does not cause pollution. We are analyzing the microbial communities responsible for this process. We have already isolated a new genus and species of thermophilic bacteria. The enzymes produced by these bacteria are also useful. Of course, we are also advancing research on the utilization of enzymes from thermophilic bacteria. To protect the environment, environmental analysis, such as water quality surveys, is essential. It is also our mission to develop more sensitive, accurate, rapid, convenient, and cost-effective analytical methods. Under joint research between industry, government, and academia, we are also investigating waste decomposition technologies utilizing the metabolic activity of thermophilic bacteria and the utilization technologies for the enzymes they produce.
