JNEP

What JNEP does

JNEP (Jiangnan Environmental Protection Group Inc., d/b/a JNEP, JNG) is a privately held Chinese environmental protection company founded in 1998 that develops ammonia-based flue gas desulfurization (FGD) and decarbonization technologies for industrial emissions control. Its core technology platform spans the EADS ammonia-based desulfurization process, the ADSC integrated desulfurization/decarbonization system, the CCUF carbon-capture-with-fertilizer-production process, the USPAC ultrasound-enhanced SO2 and particulate control system, and acid gas treatment for sulfur recovery unit tail gas. These technologies remove SO2 and CO2 from coal-fired power plant, refinery, and petrochemical flue gas and convert the captured sulfur and carbon into ammonium sulfate and ammonium bicarbonate fertilizers, eliminating wastewater and solid waste streams while meeting ultra-low emission standards (SO2 below 35 mg/Nm3, ammonia slip under 3 mg/Nm3). JNEP reports more than 500 desulfurization units installed globally, over 80% share of China's ammonia desulfurization market, approximately 2 million tons/year of installed SO2 reduction capacity, and roughly 4 million tons/year of by-product ammonium sulfate production.

JNEP monetizes primarily through large EPC (Engineering, Procurement, Construction) contracts awarded via competitive bidding to industrial clients, supplemented by technology licensing and by-product fertilizer sales. It serves power generation utilities (NTPC India, Yankuang Lunan, Wanhua Chemical Thermal Power, Ningbo Jiufeng), petroleum refineries and petrochemical complexes (PETRONAS, Sinopec Jinling, Sinopec Zhongke, Sinopec Yangzi, Shenghong Petrochemical), and chemical manufacturers (Tongliao Meihua). The go-to-market is enterprise field sales supported by participation in international summits (Carbon Capture Global Summit, Europe Summit, APAC Summit), direct engagement with government delegations, and four regional offices (Nanjing HQ, Bad Soden am Taunus, Abu Dhabi, Ridgefield Park NJ). Pricing is project-based and not publicly disclosed.

The company's IP position is anchored by 119 domestic patents and 11 international patent families totaling 159 invention patents across more than 100 countries. Recent strategic activity (2025) includes a Brazil cooperation MoU with Ambar Energy, engagement with Saudi Electricity Procurement Company at the London Carbon Capture Global Summit, listing of its CCU Complete Equipment in China's National Catalogue of Major Encouraged Environmental Protection Technologies, and ongoing multi-country field trials of its carbon-sulfur fertilizer with Syntech Research in Europe. Ownership remains founder-controlled under Chairman Xu Junsheng with no identified external PE or VC capital.
