Denox Environmental & Technology Holdings Limited (1452.HK) is an investment holding company principally engaged in the design, development, manufacture and sale of DeNOx catalysts and related air pollution control products primarily in the People's Republic of China, with operations extending to Southeast Asia and Europe. Founded in 2010 and headquartered in Beijing, the company offers plate-type DeNOx catalysts suitable for coal-fired power plants, steel, cement, metallurgy, petrochemical and other industries; honeycomb DeNOx catalysts for similar stationary sources including waste incineration and gas power generation; vehicle DeNOx catalysts for diesel and natural gas-powered applications; emerging coated catalysts such as CO oxidation catalysts for metallurgical sectors, non-methane hydrocarbon (NMHC) catalysts, hydrogen cyanide (HCN) catalysts and dioxin treatment catalysts; as well as corrugated plate-type catalysts with enhanced performance in high-temperature and anti-poisoning applications; complemented by after-sales services including sample testing, installation guidance, system commissioning and catalyst recovery. The company maintains production bases in Hebei Gu'an Economic Development Zone and Jiangsu Wuxi Economic Development Zone, with an annual catalyst production capacity exceeding 50,000 cubic meters, and holds multiple utility model patents, invention patents and software registrations derived from technologies sourced from Germany and South Korea. In recent developments, the group signed an annual group procurement agreement with a major state-owned enterprise for plate-type catalysts in 2024, achieved breakthroughs in honeycomb catalysts for shipbuilding and waste incineration power sectors, launched commercial production of corrugated plate-type catalysts following localization of production equipment and processes, improved specifications for plate-type catalysts and high-temperature high-porosity variants, gained market recognition for dioxin catalysts, and strategically reduced investments in vehicle catalyst OEM research and development at year-end 2024 to redirect resources toward industrial coated catalyst lines including CO, NHMC and HCN products amid declining vehicle orders. For 2025, the company plans intensified marketing in emerging sectors like biomass and metallurgical power, cost optimizations via supplier expansion and equipment upgrades, and overseas strategy reviews while maintaining vehicle aftermarket sales on a self-sustaining basis.
