Launched into operation in October 2019, it signified Baofeng Energy's status as one of the largest domestic coal-to-olefins producers in single-unit scale. Jingyu Environment took on the high-salt water zero-discharge project of coal-to-olefins and coal-to-methanol, treating 3,600 cubic meters of water daily and winning the high-quality project owner award from Baofeng Energy.

This project is among the first batch of coal-to-natural gas demonstration projects approved by the NDRC. The associated LNG project features a high-salt water concentration and salt separation crystallization unit using Jingyu Environment's proprietary tech, treating 13,440 cubic meters of water daily. The phase II project covers process design, equipment supply, and commissioning of the salt separation crystallization zero-discharge project, with a treatment capacity of 60 cubic meters per hour. It boosts the clean energy industry and is crucial for exploring efficient coal utilization and ensuring national energy security in NW China's coal-rich, water-scarce regions.

It's the first fertilizer-making project in Jiangsu with a sewage zero-discharge system, chosen as one of the top ten cases of ecological & environmental tech achievements in 2023 for the green, low-carbon industry. Jingyu Environment took on Linggu Chemical's sewage zero-discharge project. Its system treats 470 cubic meters of wastewater per hour, yielding 20 tons of 98.5%-pure industrial salt (NaCl, Na?SO?) daily, achieving 100% wastewater reuse and adding 2.6 million tons of recycled water yearly.

Baijiahaizi Coal Mine, a key energy project in the national and regional "14th Five-Year Plan", is situated in Shenshuitai Village, Galuotu Town, Wushen Banner, Ordos, Inner Mongolia. It's among China's largest shaft mines, with an annual output of 15 million tons and a max. underground water inflow of 3,000 m3/h. The EPC project of Baijiahaizi Mine Water & Domestic Sewage Comprehensive Utilization by Jingyu Environment is a demo under the national water-saving policy and a milestone in ultra-large zero-discharge. Given the high salt content in its mine water, Jingyu Environment adopts a process combo of three-stage high-density, pretreatment, UF, RO, NF salt separation, and evaporation crystallization to achieve zero wastewater discharge and resource utilization of sodium oxide and sulfate. This project is vital for preventing water loss and pollution, relieving water shortages, enhancing the ecological environment, and fulfilling water demands for production and daily life.

This is a crucial demonstration project in Jiangsu Province, which aims to facilitate the relocation of steel production capacity from the Yangtze River region to the coastal area. Jingyu Environment has been contracted to handle the Concentrated Water Salt Separation and Mother Liquor Treatment System within the Zhongtian Central Water Treatment Plant general contracting project. The daily treatment capacity amounts to 3,480 cubic meters. For steel enterprises, the cooling water, after undergoing evaporation, exhibits a salt concentration in the wastewater that can be several dozen times higher than that of fresh water. By means of "salt separation crystallization", Jingyu Environment further concentrates and segregates salts from the high-concentration wastewater. Sodium chloride industrial salt products are obtained through evaporation crystallization, and simultaneously, the wastewater is converted into demineralized water for complete reuse. In the process of achieving zero wastewater discharge, a 100% resource utilization rate of the entire plant's water system has been realized. This project has emerged as a novel "green and low-carbon" hallmark for the project owner and has established a new standard for environmental protection management in metallurgical enterprises.

This project, an essential safeguard one, aims to recycle industrial sewage and boost the zero-carbon industrial chain's quality construction and development.
