Our company, Rivax Co., Ltd., has been engaged in the collection, transportation, and intermediate processing of industrial waste. In response to the need for a comprehensive service that includes not only waste disposal but also factory cleaning, we launched the swell business, specializing in equipment cleaning, in 2014, and we established it as a separate entity in 2024, marking our 10th anniversary. We have a proven track record of specialized high-level work in various environments, including cleaning services focused on factory wastewater treatment facilities, piping, and tanks, as well as the collection of powdered materials, acid and alkaline sites, and long-distance horizontal piping. Our strengths lie in our ability to address customer challenges that have not been solved until now, utilizing the advanced technology of our high-performance vacuum and cleaning vehicles, and proposing better cleaning services tailored to the customer's site, contributing to improvements in cost and efficiency. With our technical expertise and proposal capabilities, we contribute to maintaining the functionality of the environmental infrastructure in factories.
