(Stock Code: 002573). The Company focuses on water services investment and operations, industrial flue gas treatment, and energy services, while actively developing high-end energy-saving and environmental protection equipment manufacturing. It is an integrated environmental protection service group encompassing technology R&D, operation and maintenance services, equipment manufacturing, engineering design, and construction. As of now, Qingxin Environment’s total assets amount to RMB 25 billion. The Company holds a National Enterprise Technology Center, a Postdoctoral Research Workstation, and multiple experimental bases; it employs over 7,000 industry professionals and operates in more than 10 countries worldwide. It is a national high-tech enterprise specializing in industrial flue gas treatment, energy conservation and carbon emission reduction, resource recycling, and comprehensive ecological environment governance. The Company was listed on the Shenzhen Stock Exchange in 2011 and is currently transitioning from a mature-stage enterprise to an ecological platform enterprise. Its core businesses cover ultra-low emission retrofits and low-carbon synergistic governance for high-energy-consuming industries—including coal chemical, petrochemical, steel, cement, non-ferrous metals, and chemical sectors—while simultaneously expanding into waste and hazardous waste resource utilization, integrated environmental services for industrial parks, full-process CCUS demonstration projects, and carbon asset development. The Company possesses end-to-end service capabilities spanning “technology R&D—equipment manufacturing—engineering implementation—intelligent operation & maintenance—resource utilization.” Its independently developed SPC-3D cyclonic atomization high-efficiency desulfurization and dust removal integrated technology and SPR single-tower integrated desulfurization and dust removal deep purification technology have been successfully applied to over 300 coal-fired power generating units rated at 300 MW or above nationwide; among these, the SPC-3D technology has been included in the National Development and Reform Commission’s “Green Technology Promotion Catalog (2024 Edition).” A 300,000-ton-per-year steel slag micro-powder production line has been constructed, establishing a technological core based on “physical-chemical synergy—intelligent control—resource regeneration,” and leveraging the “Qingxin Cloud” intelligent environmental protection platform, the Company has achieved an 8%–12% reduction in desulfurization system energy consumption and minute-level operational response times. The Company holds Class-A qualification for specialized design of environmental engineering (atmospheric pollution control engineering), Grade I qualification for professional contracting of environmental engineering, Special Equipment Production License (Pressure Piping GC1 and GB1 categories), and Level IV license for installation (maintenance/testing) of electric power facilities. It is certified under ISO 9001/14001/45001 management systems and was recognized by the Ministry of Industry and Information Technology in 2023 as a “Green Manufacturing System Solution Provider.” Representative projects include the ultra-low emission retrofit of four 1,000-MW units at Huaneng Yuhuan Power Plant; the EPC project for comprehensive flue gas treatment of the sintering machine at HBIS Group’s Handan New Area; the BOT project for hazardous waste disposal center at Sichuan Yibin Lithium Battery Materials Industrial Park; and the 150,000-ton-per-year CO₂ capture plus geological storage monitoring full-process CCUS demonstration project at the Ordos Coal Chemical Industrial Park in Inner Mongolia. Internationally, flue gas treatment EPC and O&M services have been implemented in Vietnam, Indonesia, and the United Arab Emirates. Overseas revenue accounted for 6.3% of total revenue in 2025. As the Chinese lead entity, the Company participated in drafting the ISO/TC 265 Draft International Standard No. 47, “Guidelines for Monitoring Technologies for Geological Storage of CO₂.” Currently, its international business primarily involves EPC general contracting and technical service exports. Publicly available information does not indicate substantive commercial implementation of its technologies in the EU’s Carbon Border Adjustment Mechanism (CBAM) or the U.S. Section 45Q program, nor does it show any overseas production bases or registered controlled subsidiaries.
