Detricon markets technology (patent pending) for the recovery of ammonia from waste water or air. The endproduct is a technical pure ammoniumsalt (e.g. ammoniumnitrate or ammoniumsulphate) applicable as a green fertilizer. A pilot plant is operated near the Belgian coast, treating manure and digestate, where a liquid ammoniumnitrate is produced with a concentration of 10 or 18 m% nitrogen.
