Biogas plants (anaerobic digesters) process organic waste such as manure or animal slurry, food waste from domestic, commercial and industrial sources, and sewage sludge, to produce a methane rich gas and a digestate which is typically considered a biproduct or waste.
However, the nutrient value of the digestate can be significantly improved by treating it through the N2 Unit. Commonly a doubling effect occurs making treated digestate (NEO) a stable, high nitrogen fertiliser.
For operators of biogas plants, securing an outlet for digestate is important to potentially avoid gate fees and maximize the output of the biogas plant. N2’s technology enables biogas plants to produce high quality nitrogen fertiliser from digestate utilising the energy produced locally and enhancing the overall value creation of the biogas plant.
