N2 Applied’s sludge treatment technology wins an award nomination

A sludge treatment solution that converts liquid manure into nitrogen-rich fertilizer has been shortlisted for an award recognizing green technology.

Using a technique called plasma conversion, N2 Applied’s technology ‘locks’ both methane and ammonia in liquid sludge to produce sustainable fertilizer on the farm.

Plasma-treated fertilizer has been scientifically proven to reduce ammonia and methane emissions almost completely. It also retains nitrogen to further eliminate the need for chemical fertilizers while maintaining comparable crop yields.

Now the company behind the technology has been nominated for a ‘Tech For Good’ award at the UK Business Tech Awards in recognition of its efforts to create the green solution.

Nick Humphries, Chief Agronomist and UK Director of N2 Applied, explained: “We have developed an innovative solution that uses only air and electricity to locally produce environmentally friendly fertilizers while stopping methane and ammonia emissions from livestock manure. We believe this is the most effective and integrated solution to solve the challenge.”

N2 Unit, as the technology is called, has been used in the UK, Northern Europe and South Africa, with the Scottish Rural College (SRUC) becoming the first UK purchaser and Arla Foods UK conducting a trial in his Innovation Farm where he used the technology to process manure from the farm’s 500-cow dairy herd.

Annual trial data recently released by the company from international trial sites has been independently evaluated by scientists including Oxford Agricultural Trials. It showed that the wheat crop used 85% of the nitrogen applied to the fields through the company’s fertilizer compared to 58% from an ammonium nitrate chemical fertilizer and 53% from untreated slurry.
