The aim is to develop, build and verify the operation of a processing line for the material transformation of dry sewage sludge, stabilized by anaerobic fermentation while using the energy of the organic portion of the sludge. The produced biochar will be usable as a highly porous fertilizer and at the same time as a quality component for soil cultivation and fertilization.
