There are two alternatives for the treatment of cow and chicken manure.
a) The biomass is integrated with organic carbon. In this way it is ensured that the starting mixture presents a correct relationship carbon-nitrogen (C/N), so it can be introduced inside the Biocase modules.
At the end of anaerobic digestion, biomass can be used directly in agriculture as a soil amendment.
b) The biomass is subjected to ADNEX technology.
After having reduced or eliminated the nitrogen content, cow and chicken manure can be introduced inside the Biocase modules.
At the end of anaerobic digestion, the biomass is treated by carbon dioxide or sulfuric acid, to produce respectively “calcium carbonate of defecation” or “gypsum of defecation” (BIOSOLFATO), soil corrector that is not subject to nitrates directives.
The ammonia nitrogen extract can be burned inside the genset to allow an energy recovery, or used for the production of the liquid fertilizer, ammonium sulfate
