Fields of application
Biochar produced from digestate can be used in the same way as biochar produced from any other organic raw material. Either on the own farm by spreading it on the fields. Or by refining it into other end products or by selling it.
Raw material
Digestate from biogas plants is ideally suited for the production of biochar. In a trial project spanning several years, we have optimised our plant in such a way that it produces high-quality biochar from pure digestate without the addition of other raw materials. The biochar produced by our plant from digestate meets the required EBC laboratory limits.
The digestate must first be brought to a dry matter content of 80% through separation and pre-drying. Excess waste heat from the biogas plant or excess heat from the pyrolysis plant can be used to this end.
