The output of the Poul-AR® is a substrate with acceptable N-levels to use in a thermophilic CSTR. The digester produces biogas, for the smallest installation about 1 MWe. The digestate is separated, and all liquid fraction is reused to dilute the incoming manure. The other output is the N-fertilizer. This can be ammonium sulphate or – nitrate, or any other ammonium solution, and is related to the N-content of the ingoing manure. This product is comparable to commercial available artifical fertilisers and has an average wholesale cost price of € 100/tonne. The N-fertiliser has been tested over last years through universities and farmer organisations mainly in the Netherlands, but also in other EU countries (Belgium, Spain and Italy).
