To cope with the large amounts of ammonia and methane emitted by the livestock industry into the atmosphere, the Norwegian startup N2 Applied is betting on a technology that captures most of the harmful gases and turns them into fertilizers that do not affect the climate, he explained. the ‘startup’ in its Web page.
At present, agriculture represents approximately 11% of all global greenhouse gas emissions and it is a major source of air pollution worldwide, recalls the firm.
In turn, livestock produce ammonia and methane by breaking down substances in manure and urine. These compounds can mix with other chemicals in the air, resulting in toxic smog.
The founders of N2 Applied have found a way to reduce the levels of these substances in slurry such as manure. The new device presented by Norwegian engineers acts like an air ozonator. It is installed near waste deposits by passing an electrical discharge through the air.
The reaction causes the material in the air to heat up so much that it forms a plasma stream, resulting in molecular breakdown and the release of electrons. Then, a liquid suspension is formed that prevents the formation of ammonia and finally the resulting liquid can be used as nitrogen fertilizer.
In addition to the positive impact on the climate and agriculture, this technology could also reduce unwanted odors on livestock farms.
N2 Applied claims that its device can remove approximately 90% of the ammonia and 99% of the methane that is released from manure into the air. However, the company does not specify the cost of applying this process.
