A method for obtaining a permeate in aqueous solution from a homogenized organic waste wherein the obtained permeate comprises low molecular weight fatty acids with a C1-C6 carbon chain and valuable nutrients selected from the group consisting of: nitrogen in the form of ammonium (NH4-N) or nitrate (NO3-N), phosphorus in the form of phosphates (PO4-P), and potassium, calcium, magnesium, sodium, sulfur, and boron, cobalt, copper, manganese, iron, molybdenum and zinc, comprising the steps of i. feeding the homogenized organic waste into a closed and gas tight, mixed reactor, ii. hydrolyzing and acidifying the homogenized organic waste in the reactor under thermophilic and microaerophilic conditions utilizing natural enzymes released by bacteria present in the waste, iii. separating the hydrolyzed and acidified waste obtained in step ii into o the permeate, and o an organic slurry rich in thermophilic bacteria and non-hydrolyzed organic solids, iv. re-feeding the organic slurry rich in thermophilic bacteria and non-hydrolyzed organic solids into the reactor for further hydrolysis and acidification, v. discharging the obtained permeate for further use, vi. discharging spent solids from the reactor when the concentration of fixed solids in the reactor, measured continuously, reaches a value of 40 to 50 m/m %, vii. measuring continuously temperature, redox potential, pH, and fixed solid concentration in the reactor, viii. adjusting head space pressure in the reactor to a constant equilibrium by feeding gas, formed during hydrolysis and collected in a pressure adjustment means, from said pressure adjustment means into the reactor when pressure drops in the reactor due to discharge of the permeate and/or spent solids from the reactor, ix. ensuring a hydraulic detention time of the waste in the range between 1 and 24 hours, x. adjusting the pH in the reactor to a value between 6.0 to 6.8 by addition of acid when the pH value rises above 6.8 or by addition of alkali when the pH value drops below 6.0, xi. maintaining the temperature in the reactor between 60 to 65 degree Celsius by a means for cooling and heating to ensure thermophilic conditions therein, xii. maintaining microaerophilic conditions in the reactor by adjusting the redox potential in the range of (-300) mV to (-200) mV by adding air or oxygen thereto, xiii. carrying out step i and step v at a 1:1 ratio and adding water to the reactor through a water pipe mounted to the reactor to prevent hydraulic imbalance in the reactor. i. feeding the homogenized organic waste into a closed and gas tight, mixed reactor, ii. hydrolyzing and acidifying the homogenized organic waste in the reactor under thermophilic and microaerophilic conditions utilizing natural enzymes released by bacteria present in the waste, iii. separating the hydrolyzed and acidified waste obtained in step ii into o the permeate, and o an organic slurry rich in thermophilic bacteria and non-hydrolyzed organic solids, o the permeate, and o an organic slurry rich in thermophilic bacteria and non-hydrolyzed organic solids, iv. re-feeding the organic slurry rich in thermophilic bacteria and non-hydrolyzed organic solids into the reactor for further hydrolysis and acidification, v. discharging the obtained permeate for further use, vi. discharging spent solids from the reactor when the concentration of fixed solids in the reactor, measured continuously, reaches a value of 40 to 50 m/m %, vii. measuring continuously temperature, redox potential, pH, and fixed solid concentration in the reactor, viii. adjusting head space pressure in the reactor to a constant equilibrium by feeding gas, formed during hydrolysis and collected in a pressure adjustment means, from said pressure adjustment means into the reactor when pressure drops in the reactor due to discharge of the permeate and/or spent solids from the reactor, ix. ensuring a hydraulic detention time of the waste in the range between 1 and 24 hours, x. adjusting the pH in the reactor to a value between 6.0 to 6.8 by addition of acid when the pH value rises above 6.8 or by addition of alkali when the pH value drops below 6.0, xi. maintaining the temperature in the reactor between 60 to 65 degree Celsius by a means for cooling and heating to ensure thermophilic conditions therein, xii. maintaining microaerophilic conditions in the reactor by adjusting the redox potential in the range of (-300) mV to (-200) mV by adding air or oxygen thereto, xiii. carrying out step i and step v at a 1:1 ratio and adding water to the reactor through a water pipe mounted to the reactor to prevent hydraulic imbalance in the reactor.
