China's Breakthrough Technology: Direct Conversion of Coal-Fired Power Plant Emissions into High-Efficiency Fertilizers

Can you believe it? The once vilified "environmental destroyer" from coal-fired power plants' emissions has now transformed into highly efficient fertilizers that nourish vast stretches of fertile farmland.

Chinese Solution: Transforming "Pollutants" into "Strategic Resources"

At a time when global carbon capture technology is stuck in a development deadlock, Jiangsu Jiangnan Ecology has independently developed the world's first ammonia-based integrated desulfurization and decarbonization technology for co-producing carbon and sulfur-based fertilizer. This innovation creatively redefines industrial waste gases as "strategically misplaced resources.".

The technical principle is simple and efficientThe core logic of this technology is clear and easy to understand, with the entire process completed under normal temperature and pressure, eliminating the need for harsh conditions such as high temperatures and high pressure Desulfurization stage: Precisely absorb sulfur dioxide from the flue gas using ammonia to generate ammonium sulfateDecarbonization stage: Continue using ammonia to absorb carbon dioxide from the flue gas after desulfurization, generating ammonium bicarbonateFinished product stage: Add a special booster agent, mix and granulate according to scientific proportions, and finally produce a carbon-sulfur-based booster fertilizer

It is astonishing that this technology achieves over 90% efficiency in both decarbonization and desulfurization, with no wastewater, exhaust gas, or waste residue generated throughout the process. Ammonia slip is controlled below 3mg/Nm³, far below the nation's most stringent emission standards. According to a comprehensive life-cycle carbon footprint analysis by authoritative institutions, every 1 million tons of CO₂ removed results in approximately 2.34 million tons of net CO₂ reduction—more than three times that of conventional technologies.

Cost advantage creates a dimensional reduction strike

Compared to traditional geological sequestration technologies, Jiangnan Ecological's technology demonstrates overwhelming advantages in terms of cost

Investment cost: The total investment for the entire industrial chain is only about 1,500 yuan per ton of CO₂, less than half of traditional technologies

Operating cost: 40%-90% energy saving compared to traditional methods, with a 50%-90% reduction in operating costs

Revenue Model: Generate stable cash flow through fertilizer sales, which can fully offset or even exceed carbon capture costs

The first demonstration project has been successfully implemented

In August 2025, the world's first industrial demonstration project for "flue gas-to-fertilizer" with a capacity of 10,000 tons was successfully connected to the grid and put into operation at Jiu Feng Thermal Power in Ningbo, Zhejiang. This facility can annually:

Capturing 10,000 tons of carbon dioxide is equivalent to the annual carbon sequestration capacity of 2,667 acres of mature forest

Approximately 30,000 tons of high-quality carbon-sulfur-based compound fertilizer

Simultaneously absorb all the sulfur dioxide emitted by the power plant
