Together with biogas, the so-called “digestate” is the main product of anaerobic digestion. Digestate is the material remaining after the anaerobic digestion of a biodegradable feedstock. Can replace mineral fertilisers with environmental and economic advantages.
The digestate resulting from anaerobic digestion of manure and slurry, the so-called “biogas-slurry,” is much appreciated as a safe, organic, liquid fertilizer. This organic fertilizer is rich in phosphorus, which is an essential plant nutrient but increasingly scare.
