共和化工 Company Overview

We aim to be a trusted company that coexists with society, while also challenging ourselves to create and innovate technology, striving to be a vibrant company with rich human qualities that can lead through technology.

Since our founding, we have been working daily to improve water treatment technology with the theme of "restoring natural water." In the treatment of wastewater from meat processing centers, we developed the unique Kyowa-style two-stage oxidation method, establishing ourselves as pioneers in high-concentration treatment. Additionally, at the leachate treatment facility for final disposal sites, we have introduced the first desalination system in the water treatment industry and are expanding it nationwide. Furthermore, based on our additional theme of "purifying water and revitalizing the earth," we are undertaking a new business initiative focused on ultra-high-temperature aerobic fermentation treatment using YM bacteria. At the Environmental Microbiology Research Institute, we have invited the renowned researcher Dr. Tairo Oshima, who is well-known in the field of ultra-high-temperature aerobic microorganisms, to work daily on the creation of technologies and the development of new techniques using microorganisms.

Business Activities

【Water Treatment Business】 Our company is engaged in addressing wastewater treatment issues with the theme of "restoring water." We have developed superior technology, the "Kyowa-style two-stage oxidation method," which is unmatched by other companies. We have constructed water treatment facilities in various fields, including public sewage treatment, general industrial wastewater, and livestock wastewater treatment, and have been working to prevent pollution. Notably, in the treatment of wastewater from meat processing centers, we have established a unique position as a pioneer and continue to maintain a top market share. 【Recycling Business】 The recent societal system of mass production, mass consumption, and mass disposal has exceeded nature's purification capacity, exacerbating various environmental issues such as global warming and desertification. Building a sustainable circular society that effectively utilizes limited resources has become an urgent global challenge. In this context, our company has established ultra-high-temperature aerobic fermentation technology using YM bacteria and, in April 2002, formed a technical partnership with Yamari Co., Ltd., which has over 20 years of experience, and has been granted the right to implement their patented technology.

Recycle food on your own! Fermentation processing device that circulates fertilizer - YM Himawari-kun.

  • PRODUCT

Powerful decomposition of organic matter through ultra-high temperature fermentation! A groundbreaking product that also reduces running costs. Achieve food recycling on your own! YM Himawari-kun is a fermentation treatment device that utilizes the power of YM bacteria to strongly decompose organic matter. It contributes to the suppression of global warming and is a revolutionary product that can achieve complete recycling by utilizing our recycling network. 【Features】 ● Ultra-high temperature fermentation by YM bacteria The fermentation heat from YM bacteria sterilizes and kills weed seeds, decomposing organic matter. The resulting products can be effectively used as fertilizers and soil conditioners. ● Environmentally friendly with suppressed CO2 emissions By converting organic waste into fertilizer without using fire, CO2 emissions are suppressed, and no harmful substances are generated. ● Adoption of a rotary type for low costs Energy-efficient design significantly reduces running costs.
