Production of value added products from separately collected urine

For many reasons it is advantageous to collect urine separately and collection systems, so called "no-mix-toilets" exist. Therefore, this work deals with some methods to make use of this urine to produce value added products: IBDU and ammonia water. It could be shown that urea can be converted to IBDU only after concentrating urine. With air stripping and absorption ammonificated urine can be treated very effectively and a solution of 10% w/w of ammonia can be obtained.
