Abstract

There is a need to take care of the nutrients in the system. Anaerobic digestion is a valuable way to convert the nutrients and produce renewable energy. A model is presented that use grass-clover as feedstock for anaerobic digestion and separate the digestate in 3 fractions. Anaerobic digestion and separation have positive effect on N2O-emissions. But a very dilute solution of ammonia and sulfur generated high emissions when applied to the soil with 100 kg N per hectare.
