In 2025, Aotu (Kaifeng) was listed as a reserve enterprise in Henan Province. It collaborated closely with the century-old prestigious university, Henan University, and undertook the major scientific and technological project of "Challenge and Solution" in Henan Province. This move aimed to further enhance Aotu's technical capabilities.

In the future, AoTu will continue to uphold the "One Health" concept. Focusing on the big health industry, driven by AI chemistry, it will develop new technologies for environmental improvement, new electronic information materials, and new biodegradable materials, achieving vertical diversification and coordinated development. AoTu will make its contribution to the comprehensive improvement of living environment, breeding environment, and soil environment.

industrial-scale synthesis device for potassium permanganate hydrogen peroxide complex salt (PMPS) in Shanghai. Since 2011, based on different application scenarios of oxidants, they have deeply innovated and provided customized and superior solutions for customers, with market demand increasing 100-fold over 20 years.

oxidants, and the "Hong's Ten-Point Policy" for selecting ideal disinfectants. Among them, the reaction kinetics of chemical disinfectants was recognized by Professor Xue Guangbo, the founder of Chinese disinfection science, as "laying the foundation for establishing a new discipline of mathematical disinfection science".

The plan for the AoTu Kaifeng production base began in 2017, including the batch production of PMPS, γ-PAG, and 20,000 tons/year water and soil improvement agent project for environmental improvement using microorganisms. PMPS adopts the internationally leading microchannel continuous flow synthesis process, achieving intrinsic safety and environmental friendliness in chemical reactions. AoTu (Kaifeng) has successively received certifications as a national high-tech enterprise, a provincial specialized and innovative enterprise, and a provincial engineering technology research and development center. It is one of the leading drafters of several national and industry standards related to water treatment, infectious disease disinfection, and soil remediation. It has obtained more than 20 related patents and its products have been exported to 26 countries and regions. Its market share in the domestic market is leading, and the procurement rate from leading enterprises is 100%. AoTu has passed ISO9001, ISO14001, and ISO45001 system certifications.
