What Cathay Pacific Environmental Protection does

Hangzhou Guotai Environmental Protection Technology Co., Ltd. (杭州国泰环保科技股份有限公司), founded in 2001 and headquartered in Xiaoshan District, Hangzhou, Zhejiang Province, is a publicly listed (szse:301203) Chinese environmental engineering and technology enterprise specializing in sludge treatment and resource recovery, pollution control, and the treatment and resource recovery of waste gas, wastewater, and solid waste (the 'three wastes'). The company's core proprietary technology is a domestically pioneering sludge deep dewatering system that reduces 80% moisture-content sludge to approximately 45% (some as low as 40%) under ambient temperature and low pressure, decreasing sludge volume by over 60% without secondary pollution. This technology was designated a national 11th Five-Year Plan water special project in 2008 and passed national acceptance in 2013. The firm also operates a portfolio of complementary process technologies — multi-stage coupling oxidation, Fenton catalytic oxidation, and sulfur-based autotrophic denitrification — for industrial wastewater treatment, plus petrochemical waste resource recovery for organic residues from DMC, DPC, EO/EG, MMA process units. The company holds 60+ patents and proprietary technologies and has completed 10 national/provincial-level major science and technology projects.

The company's commercial model is B2B project-based, delivering environmental engineering services through an EPC (Engineering, Procurement, Construction) model, complemented by technology licensing and long-term operational service contracts. Revenue is generated from technology development, engineering design, project construction, and ongoing operation of sludge dewatering and wastewater treatment facilities. Customer segments include large municipal sewage treatment plants (Hangzhou, Shaoxing, Shanghai, Nanchang), ultra-large petroleum refining and petrochemical enterprises (Zhoushan, Ningbo), and emerging-industry manufacturers in lithium battery, semiconductor, and consumer electronics supply chains, alongside traditional chemical, pharmaceutical, and printing/dyeing industries. The company maintains R&D platforms including a provincial enterprise research institute, a provincial high-tech enterprise R&D center, the Tongji-Guotai Environmental Protection Engineering Technology Center, and a cooperation agreement with the Zhejiang Academy of Agricultural Sciences' Institute of Environmental Soil Science. Its 2026 strategic cooperation agreement with Zhejiang Ecological Environment Group positions the firm to scale provincial-level deployment under China's dual-carbon strategy and 15th Five-Year Plan carbon management framework, with headcount in the 251–500 range.

Core offering

Hangzhou Guotai Environmental Protection provides proprietary sludge deep dewatering technology, industrial wastewater treatment processes (multi-stage coupled oxidation, Fenton catalytic oxidation, sulfur-based autotrophic denitrification), and three-wastes (waste gas, wastewater, solid waste) treatment and resource recovery solutions, sold via EPC project contracts, technology licensing, and long-term operational services to municipal wastewater plants, petrochemical refineries, and emerging-sector manufacturers in China.

Product overview

杭州国泰环保科技股份有限公司 operates as a specialized environmental protection enterprise founded in 2001, offering an integrated portfolio of waste treatment and resource recovery technologies. Its core offerings include the proprietary 污泥深度脱水技术 (Deep Sludge Dewatering Technology) — a domestically pioneering solution that dewateres high-moisture sludge under ambient conditions — complemented by 污染控制与清洁生产技术 (Pollution Control and Clean Production Technology) and 三废处理与资源化技术 (Three-Wastes Treatment and Resource Recovery Technology). The company also provides sector-specific solutions such as 石化行业固废/有机废液资源化技术 (Petrochemical Waste Resource Recovery), and process technologies including 多级耦合氧化技术 (Multi-Stage Coupled Oxidation), 芬顿催化氧化技术 (Fenton Catalytic Oxidation), and 硫自养反硝化技术 (Sulfur-Based Autotrophic Denitrification). Together, these offerings address the complete waste lifecycle — from dewatering and stabilization to resource recovery and final disposal — serving traditional manufacturing industries (chemical, pharmaceutical, printing and dyeing) as well as emerging sectors (lithium batteries, semiconductors, new materials).
