Hacking the fertilizer value chain

The Norwegian technology company N2 Applied has developed a technology that enables livestock farmers to efficiently recycle nitrogen on the farm and produce fertilizer with lower greenhouse gas emissions.

Nitrogen is an essential nutrient to plant growth. However, the nitrogen content of manure is too low for the balanced fertilization of most crops. Ammonia loss during the storage and application of the manure is also common. The root of the problem is the biological decomposition which releases ammonia, which, in turn, increases the greenhouse gas emissions from agriculture. N2’s technology enables livestock farmers to recycle nitrogen and produce fertilizer with lower greenhouse gas emissions, improved resource efficiency and reduced cost. The N2 plasma reactor fixates nitrogen from air by splitting the nitrogen and oxygen molecules in air into atoms forming nitrogen oxides. The nitrogen oxides are then absorbed into liquid manure or biogas digestate and combined with free ammonia to form stable ammonium nitrate fertilizer. N2 Applied’s absorption system can be adapted to various types of manure or digestate. All N2 plasma reactors are connected to N2 Cloud, a digital environment where all production data is stored and analyzed. The cloud solution enables remote operation and maintenance of the reactors and forms the basis for value-added services to the farmer.
