What 上海泰欣环境工程股份有限公司 does

Shanghai Taixin Environmental Engineering Co., Ltd. (上海泰欣环境工程股份有限公司), operating as Techspray Environmental Protection Co., Ltd. and listed on China's NEEQ under stock code 837783, is an industrial engineering and technology services company specializing in flue gas purification systems, with a dominant position in China's municipal solid waste incineration sector. Its core product portfolio comprises modular flue gas treatment systems including Selective Non-Catalytic Reduction (SNCR) denitration, low-temperature Selective Catalytic Reduction (SCR) denitration operating at 170–230°C, dry, semi-dry, and wet acid gas removal systems, activated carbon injection for dioxin and heavy metal control, and a proprietary leachate concentrate re-spray system enabling zero liquid discharge at waste-to-energy plants. These modules are combined into integrated ultra-clean emission processes achieving near-zero pollutants (NOx <50mg/Nm³, SOx <10mg/Nm³, dust <5mg/Nm³, dioxin <0.05ng-TEQ/Nm³), well below Chinese GB18485-2001 standards and meeting EU 2000 benchmarks.

The company reports over 60% domestic market share in SCR/SNCR denitration for waste incineration plants and over 40% in wet flue gas purification, with more than 300 customers and nearly 700 installations across waste-to-energy, paper, cement, petrochemical, and thermal power sectors. Its go-to-market is direct enterprise field sales through public tenders, invitation-based bidding, and direct negotiation, with projects delivered under EP (design-procurement) and EPC (design-procurement-construction) contracts valued on a project-by-project basis. The company holds exclusive technology licensing from Hitachi Zosen (wet acid removal, low-temperature denitration) and GEA Niro, and serves flagship customers including Everbright International, Shenzhen Energy Environmental Protection, Sound Environment, Kangheng Environment, Shanghai Environment Group, and Guangzhou Environmental Investment Group. Revenue is recognized at project completion/acceptance, creating lumpiness, with 2016 revenue of 43.6M RMB and 2017 H1 revenue of 74.1M RMB (up 160.65% YoY).

Founded in 2008, originally as Shanghai Qinxin Environmental Protection Complete Equipment Co., Ltd., and rebranded to its current name in 2012 and share-company form in 2016, the company became a wholly-owned subsidiary of state-controlled listed company Wuhan Donghu Gaoxin Group (stock code 600133) in 2019. It operates from Shanghai Pudong and maintains two subsidiaries: Shanghai Bojie Environmental Protection Engineering (60% owned, pending deregistration) and Shanghai Chengyue New Energy Technology (100% owned), with international operations extending into Southeast Asia and Africa. As of mid-2017 the company employed 88 people and held 18 patents including 5 invention patents, 11 utility models, and 2 software copyrights.

Broad incumbents

• CECEP (China Energy Conservation and Environmental Protection Group): Largest state-owned environmental industry group in China, operating across energy conservation, waste-to-energy, water treatment, and atmospheric pollution control. Functions both as a major customer and indirect competitor to Techspray through its broader environmental engineering portfolio.
• ANDRITZ: Austrian global engineering group with a substantial environmental technologies segment covering air-pollution control, scrubbers, and emissions reduction for power and industrial customers. Comparable to Techspray at the system level but operates at much greater scale and geographic breadth.

Emerging players

• Hamon: Belgian engineering firm specializing in industrial cooling systems and air-pollution-control equipment including wet scrubbers and FGD systems for power and industrial markets. Overlaps with Techspray's wet acid removal / wet FGD offerings, particularly in international markets.
• Sumitomo Heavy Industries: Japanese industrial conglomerate with environmental equipment offerings including flue gas treatment and waste-to-energy systems. Serves similar emissions-control end-markets as Techspray and competes in Asia, though with a much broader industrial portfolio.
• Babcock & Wilcox: US-based boiler and emissions-control equipment manufacturer offering SCR systems, wet and dry scrubbers, and particulate control for power and industrial applications. Comparable to Techspray in flue gas treatment technology portfolio, with stronger global reach but a weaker position in Chinese WtE.

Direct peers

• Hitachi Zosen: Japanese industrial engineering firm (TSE: 7004) and global leader in waste-to-energy plants and flue gas treatment systems. Both a direct competitor in WtE emissions control and Techspray's key technology licensor for wet FGD and low-temperature denitration, making it the most strategically relevant international peer.
• Feida Environmental Protection (菲达环保): Major Chinese electrostatic precipitator and air-pollution-control equipment manufacturer (SSE: 600526), serving coal-fired power, waste-to-energy, and industrial customers. Comparable to Techspray in flue gas treatment end-markets, though historically stronger in ESP and dry systems than in SCR.
• Longking Environmental (龙净环保): China's largest air-pollution-control equipment company (SSE: 600388), covering dust removal, denitration (SCR/SNCR), and desulfurization (FGD) for power and WtE plants. Direct competitor to Techspray across flue gas treatment technologies with a much broader portfolio and larger installed base.
• Chongqing Yuanda Environmental Protection (重庆远达环保): Chinese SCR catalyst and air-pollution-control equipment manufacturer affiliated with China Energy Engineering Group. Direct competitor in SCR catalyst and denitration systems for thermal power and WtE plants, with state-owned enterprise backing similar in profile to Techspray's parent.

Regional players

• Doosan Enerbility: Korean power plant and environmental equipment manufacturer offering SCR catalysts, electrostatic precipitators, and flue gas treatment systems primarily in Korea and Southeast Asia. Comparable to Techspray in technology stack but serves different core geographic markets.
