On-site Green Fertilizer Production from Air and Waste Gases

environmentPrototypeTRL 3

Imagine a device that acts like an artificial leaf, sucking up pollution and CO2 from the air or factory smoke. Instead of just cleaning the air, it turns those pollutants into liquid fertilizer right where the plants are growing. This removes the need to buy, transport, or store heavy bags of chemicals.

The business problem

What needed solving

Traditional fertilizer production relies on fossil fuels and creates significant CO2 and nitrogen pollution. Additionally, the logistics of transporting and storing these chemicals increase costs and environmental damage.

The solution

What was built

A lab-scale prototype including AHA IL-based membranes for CO2 capture and an electrolyser for converting nitrogen and CO2 into urea.

Business applications

Who can put this to work

Precision Agriculture
mid-size
Target: Smart farm operator

If you are a smart farm operator dealing with high transport costs and soil runoff — this project developed a self-sustaining system that converts CO2 and nitrogen into urea in situ. This allows for autonomous fertilizer delivery without the need for storage and transport.

Industrial Emission Control
enterprise
Target: Factory with flue gas emissions

If you are a factory owner dealing with carbon taxes and nitrogen pollutants — this project developed an electrochemical system that captures CO2 and N-compounds directly from flue gas. It turns a waste liability into a sellable or usable fertilizer product.

Green Chemistry
SME
Target: Sustainable fertilizer manufacturer

If you are a manufacturer dealing with reliance on fossil fuel-based ammonia production — this project developed a lab-scale technology using solar photocatalysis and electrochemistry. It enables the production of urea using renewable energy sources instead of natural gas.
