Product description

The digestate of Arbio (biogas installation digesting manure and organic wastes) is separated into a liquid and a solid fraction. The liquid fraction is concentrated via Reverse Osmosis (RO). This concentrate (NK) is then backmixed into the drying of the solid fraction digestate just before drying. Finally, pelletised, this results in an easy to distribute fertiliser-pellet with an optimised and higher N/P-content: 5,5% N (TN fresh weight) of which 50% mineral N, and 2,8% P2O5 (fresh weight). The nitrogen in the concentrate is due to the high ammonium content on the one hand very easily absorbed by plant roots but volatilizes quickly on the other hand and must therefore be used professionally. In the new Fertiliser Regulation dried digestate (pellets) can be  categorized as PFC 1 A (solid organic fertiliser) or PFC 3 A (organic soil improver) or in blend).  At the end of 2019 the full industrial scale of the NPirriK post-treatment flow can realise about 1500 tonnes/y of the high N/P-pellets. The market price for the pellets is estimated to rise due the optimised post-treatment add-on from 25€/t to 45€/t. The second RO-stream - water - can under certain conditions be either discharged into surface water, used as process water or, in case of drought, be used to irrigate nearby agricultural plots.
