NOVELTY - Processing organic side flows and waste slurries e.g. industrial waste slurries, in connection with a bio refinery e.g. ethanol production arranged in communication with an industrial facility, comprises: treating the waste slurries in at least one of a ethanol production (12) and biogas production to produce ethanol and/or biogas and residual organic slurry; and combining the residual organic slurry with an applicable drying agent for drying the slurry and for producing a granular product capable of being used as a fertilizer and/or a soil enrichment agent.    USE - The method is useful in waste water treatment plants. The method is useful for the preparation of the granular product as fertilizer and/or soil enrichment agent.    ADVANTAGE - The method: is safe and inexpensive; reduce the amount of waste from final disposal; reduces the need for chemical fertilizers; and produces cleaner waste waters; and does not require chemical process. The total energy produced in the process is greater than the energy from separate processes.    DETAILED DESCRIPTION - Method of processing organic side flows and waste slurries in connection with a bio refinery arranged in communication with an industrial facility, where the organic side flows and waste slurries comprises at least one of industrial waste slurries, municipal bio waste slurries, municipal waste waters and agriculture slurries, and the bio refinery comprises ethanol production, bio gas production, and algae farming to produce residual organic slurry and at least one of hydrogen, bio ethanol and bio gas, comprises: treating the waste slurries in at least one of a ethanol production (12) and biogas production to produce ethanol and/or biogas and residual organic slurry; and combining the residual organic slurry with an applicable drying agent for drying the slurry and for producing a granular product capable of being used as a fertilizer and/or a soil enrichment agent. An INDEPENDENT CLAIM is included for a fertilizer that is formed of residual slurry collected from at least one of ethanol production and biogas production and a drying agent.
