Tongxing Environmental Protection Technology Co., Ltd. was founded in 2006. It is a listed company on the Shenzhen Stock Exchange (stock code: 003027) . It is a well-known domestic comprehensive service provider for flue gas treatment in the non-electric industry. The company's core business is the production and supporting services of general contracting of environmental protection engineering (EPC ) and low temperature (SCR) denitrification catalysts. It has the Class A qualification for environmental engineering design, Class A professional contracting qualification for environmental protection engineering, pressure pipeline design qualification and Pressure vessel design and manufacturing qualifications are the executive director unit of China Environmental Protection Industry Association, the member unit of metallurgical enterprise of China Energy Conservation Association, the member unit of Coking Industry Association, and the outstanding private enterprise in Anhui Province. They have been recognized as "high-tech enterprise" for many years.

Since its establishment, Tongxing Environmental Protection has taken the responsibility of controlling industrial waste gas pollution and recreating clear water and blue sky as its mission, and is committed to technological innovation. It has joined hands with professional institutions such as China University of Science and Technology, Beijing University of Technology, Dalian University of Technology and MCC Jiaonai to create Beijing and Anhui. The two industry, academia and research bases have achieved a series of scientific research results. The company undertakes and completes the Ministry of Science and Technology’s “Innovation Fund” project and participates in the formulation of the “Coking Industry Clean Production Level Evaluation Standard”; “Sintering Node Flue Gas Low Temperature SCR Denitrification Technology and Equipment”, “Key Techniques and Equipment for Flue Gas Denitrification Catalyst Materials for Industrial Furnace Kiln Flue Gas and Industrialization, "coke oven flue gas desulfurization and denitrification technology and equipment" reach the international advanced level; "coke oven waste gas desulfurization and denitrification integrated device" technical level is at the forefront of the domestic technology; "Corresistance and low temperature selective catalytic reduction (SCR) in coke oven flue gas Denitrification technology, coking flue gas rotary spray desulfurization + SCR denitrification technology" was included in the 2018 "National Advanced Pollution Prevention and Control Technology Catalog (Field of Air Pollution Prevention and Control)" by the Ministry of Ecology and Environment.

As of the end of 2021, the company's environmental protection engineering performance has spread to more than 20 provinces, cities and autonomous regions across the country. It has made positive contributions to the owners' units' ultra-low emissions, and has gained high product visibility and recognition. It has become my country's steel, coking, The new force in energy conservation and emission reduction in building materials, industrial furnaces, waste incineration, glass, ceramics, industrial silicon and other industries and the backbone of low-temperature desulfurization and denitrification.
