An industrial wastewater treatment company built around what happens after treatment
Shanghai Jingyu Environmental Engineering Co., Ltd. is an industrial wastewater treatment company that has worked since 2009 at the hardest end of the water business: high-salinity streams, landfill leachate, and the brine that other processes leave behind. We design, build, and operate the systems that turn those streams into reusable water and salable industrial salt.
An industrial wastewater treatment company since 2009
JINGYU is headquartered in Shanghai and was founded in 2009 with registered capital of RMB 175 million.
The group operates through 7 wholly owned subsidiaries, 8 controlled entities, and 6 branch offices, with regional presence in Beijing, Ordos, Xi'an, Baoji, Panzhihua, Huaibei, Nantong, Nanjing, and Xinjiang. In FY 2025 the group reported approximately USD 170 million in revenue and USD 160 million in total assets.
Our work concentrates on two things that most water companies treat as separate: zero liquid discharge for complex industrial streams, and the recovery of that discharge as a product. In 2025 we established our International Business Division to bring that capability to clients outside China.
What we do
We cover the full chain, from bench-scale process development through construction, commissioning, and fifteen-year operating contracts. Clients engage us for a single piece of that chain or for all of it.
Process and design
Water quality analysis, pilot testing, process package development, and detailed engineering design.
Equipment and delivery
Core process equipment supply, system integration, EP and EPC delivery, construction, and commissioning.
Operation
Long-term O&M with performance-aligned KPIs, delivered by an in-house team of more than 650 operators.
Investment models
BOO, BOT, TOT and ROT structures for owners who prefer to buy treated water rather than build a plant.
How we got here
JINGYU did not start in zero liquid discharge. Each capability we sell today came out of a problem a client could not solve, and the sequence explains why the company looks the way it does.
2009 to 2014: leachate and photovoltaic water
Shanghai Jingyu Environmental Engineering Co., Ltd. is founded in Hongkou District, Shanghai. First demonstration project completed: high-recovery water reuse for a photovoltaic manufacturer.
Our photovoltaic wastewater process is adopted across the sector and recognized as a reference technology.
Landfill leachate treatment technology developed in-house, addressing a treatment gap the Chinese market had no domestic answer for.
The leachate concentrate problem is solved. We develop humic acid extraction from nanofiltration concentrate, and a volume reduction process for reverse osmosis concentrate.
Zero liquid discharge applied in the photovoltaic industry. Pilot campaign completed for coal chemical high-salinity brine ZLD.
First food waste leachate project delivered. Leachate treatment plants built for Shenzhen Energy, Shanghai Chengtou, Everbright Environment, Dynagreen, Beijing Enterprises, and Capital Environment.
2015 to 2020: brine, salt, and owned assets
Purification, evaporation, crystallization, and selective salt separation for industrial brine reach full-scale validation. Three strategic transformation targets are set for the company.
Formal entry into the industrial brine market, giving the company two parallel lines: municipal leachate and industrial high-salinity wastewater.
Strategic equity investment from Yitai Group, Tsinghua Tus-Holdings, and Hongrui Group. China's first coal chemical ZLD plant with crystallized salt recovery enters service, separating industrial salt that meets national product standards. Headquarters relocates to Baoshan District, Shanghai.
Regional subsidiaries established across China. We introduce the EFO model, combining integrated design, project financing, and operating service in one contract.
Yitai Hongqinghe mine water ZLD plant starts up. The Huineng coal chemical ZLD project enters production.
Hongqinghe begins commercial operation as a BOO asset, our first large-scale mine water ZLD plant owned and operated in-house. First steel industry ZLD project awarded.
2021 to 2025: scale, and beyond China
Entry into the petrochemical sector. Coking wastewater ZLD with crystallized salt recovery delivered, producing salt to industrial specification.
Construction starts on the Baijiahaizi mine water ZLD plant, our largest by design capacity at 72,000 m³/d. Full water system ZLD awarded for the world's largest integrated BDO production base.
Waste salt recovery and reuse technology reaches commercial deployment. Contract awarded for Huaneng Group's Qingyang Xinzhuang project.
Recognized as a national Specialized and Sophisticated "Little Giant" enterprise. Strategic cooperation agreement signed with Huaneng Yangtze Environmental Technology. Xinjiang branch established.
International Business Division established to deliver ZLD and resource recovery projects outside China.
Research and development
Three research institutes and more than 1,500 m² of pilot testing and analytical facilities support every process package we sell. Work runs from water quality analysis and bench trials through to full-scale engineering validation on the client's actual wastewater.
