Ranking of Chinese environmental protection equipment enterprises—leading companies categorized by sector (Source: Industry reports/listed company financial statements): Longking Environmental ranks first with a 6.2% market share (the world’s largest manufacturer of industrial flue gas treatment equipment, holding approximately 21% of the market for ultra-low emission desulfurization and denitrification in thermal power plants); Feida Environmental operates with a dual-engine strategy of atmospheric treatment and water services; Yingfeng Environment ranks high in net profit for environmental equipment (477 million RMB, Source: Stockstar)—the top ten companies in the industry hold a combined market share of 38.6% (indicating a fragmented landscape), so leading companies are best selected by specific sector.
I.
Leaders in Atmospheric Treatment
Longking Environmental (600388): The world’s largest manufacturer of industrial flue gas treatment equipment, offering a full range of technologies including electrostatic precipitation, low-low temperature electrostatic precipitation, wet electrostatic precipitation, and ultra-clean electric-bag composite precipitation; holds approximately 21% of the market for thermal power plant retrofitting (Source: 2025 Annual Report); Feida Environmental (600526): Established in 1969 in Zhuji, Zhejiang, and a national benchmark for flue gas treatment (dust removal + desulfurization/denitrification); Qingxin Environment (002573): An operator of desulfurization and denitrification facilities; Zijin Longking: Ranks first in net profit at 557 million RMB (+25%, Source: Stockstar)—choose Longking or Feida for dust removal and desulfurization in power plants and steel mills.
II. Water Treatment & Solid Waste
Capital Environment (首创环保): Industry leader in water services & solid waste (full industry chain operations); Hongcheng Environment (洪城环境): Wastewater treatment design capacity of 4.234 million m³/day (dividend yield: 5.17%); Weiming Environment (伟明环保): Leader in waste incineration (market cap of RMB 27.49 billion, ranking among the top in the industry); Gaoneng Environment (高能环境): Hazardous waste & soil remediation; Zhefu Holdings (浙富控股): Renewable resources—for wastewater, choose Capital Environment or Hongcheng Environment; for waste incineration, choose Weiming Environment (operational services selected based on region).
III.
Equipment Manufacturing Sub-sectors
Yingfeng Environment (000967): Sanitation equipment & environmental protection equipment (leader in new energy sanitation vehicles); Huahong Technology (002645): Renewable resource processing equipment (net profit RMB 343 million, up 330%); Jinke Environment (金科环境): Water treatment membrane equipment; Zhengzhou Puhua / Beijing Song’an: Specialized manufacturers of bag-type dust collectors; CECEP Environmental Protection (中电环保): Flue gas & water treatment (small market cap with high growth potential)—equipment manufacturing selected by category (sanitation: Yingfeng; dust removal: Puhua; renewable resources: Huahong).
IV.
Overseas Procurement Recommendations
First, consider the target of treatment (flue gas: Longjing/Feida; wastewater: Capital Environment; solid waste: Weiming); second, check certifications (CE/ISO 14001 + compliance with emission standards); third, examine project case studies (track record in the industry); fourth, compare EPC capabilities (integrated delivery of Design-Procurement-Construction); fifth, verify operational data (actual emission concentrations/treatment efficiency)—for overseas B2B procurement of environmental equipment: determine emission standards first, then select the enterprise (industry leaders ensure compliance; EPC offers turnkey delivery).
V. Trends
Ultra-low emissions: Retrofitting for ultra-low emissions in thermal power and steel sectors (integrated desulfurization and denitrification); Dual Carbon goals: Emerging markets for carbon capture and energy-saving equipment; Smart environmental protection: Digitalization of monitoring and O&M;
Going global: Export of Chinese environmental equipment to Southeast Asia, the Middle East, and Africa (leveraging cost-effectiveness and EPC capabilities)—Key Chinese enterprises: Longking/Feida (Air), Capital Environment/Hongcheng Water (Water), Weiming (Solid Waste), Infore Environment (Sanitation) (categorized by sector; meeting compliance and acceptance standards).
