Poul-AR® Pilot Plant

The Colsen group has developed the eco-innovate Poul-AR® process a sustainable route to nutrient recovery and energy efficiency from poultry manure. The first step in the process is the biological ammonification of the manure to convert organic nitrogen into ammonia. The ammonia present in the broth is then recovered via air stripping after which it is fixated with nitric acid as an ammonium salt to produce the desired fertiliser. The residue rich in organics it then thermophilically digested to produce biogas and phosphate rich digestate.
