Circular Agronomics > Recovering nitrogen from agricultural waste

A new pilot plant for nitrogen recovery from agricultural waste and intended to tackle nitrate contamination in groundwater has become operational in February 2020 in Berge, Germany. The plant was designed and built within the framework of Circular Agronomics by project partners PONDUS Verfahrenstechnik GmbH and Kompetenzzentrum Wasser Berlin gGmbH (KWB).

The plant will allow for a separation of nitrogen from the digestate high-carbon fraction and, subsequently, for an adequate soil improvement by means of carbon or by soil fertilisation with nitrogen. In particular, this approach will have a positive effect on the groundwater, since the nitrogen can be selectively applied.
