The bio-chamber has a chamber body that defines a receiving chamber and an aeration chamber. The aeration chamber underlies the receiving chamber and is divided therefrom by a partition. The partition has a plurality of holes formed therein. An oxygen probe and a temperature probe are positioned inside the receiving chamber. An air blower is connected to the aeration chamber and is operable to blow air therein. The method comprises: mixing the poultry manure with a carbon carrier; loading the mixture into the receiving chamber; monitoring the temperature and the oxygen concentration of the mixture; aerating the mixture; and regulating the temperature and the oxygen concentration by adjusting the operation of the air blower. The temperature and oxygen concentration are regulated to provide conditions that permit aerobic bacteria to propagate and biodegrade the mixture. ## Claims ### Claim 1 A bio-chamber for producing organic fertilizer, the bio-chamber comprising: a chamber body defining a receiving chamber and an aeration chamber, the aeration chamber underlying the receiving chamber and being divided therefrom by a partition, the partition having a plurality of holes formed therein; at least one oxygen probe positioned inside the receiving chamber; at least one temperature probe positioned inside the receiving chamber; and at least one air blower connected to the aeration chamber and operable to blow air therein. ### Claim 2 (depends on 1) The bio-chamber according to claim 1, further comprising: a plurality of said oxygen probes, at least one of said oxygen probes being positioned in each of a lower region, a middle region, and an upper region of said receiving chamber; and a plurality of said temperature probes, at least one of said temperature probes being positioned in each of the lower region, the middle region, and the upper region of said receiving chamber. ### Claim 3 (depends on 1) The bio-chamber according to claim 1, wherein said plurality of holes are arranged in a grid pattern, the grid pattern defining a plurality of square cells, with one said hole being positioned at each node of the grid pattern, and one said hole being positioned at a center of each of said cells. ### Claim 4 (depends on 3) The bio-chamber according to claim 3, wherein the cells are approximately 10 cm by 10 cm. ### Claim 5 (depends on 1) The bio-chamber according to claim 1, wherein the holes have a width of 4 mm to 5 mm. ### Claim 6 (depends on 1) The bio-chamber according to claim 1, further comprising: an exhaust fan connected to the receiving chamber. ### Claim 7 (depends on 1) The bio-chamber according to claim 1, further comprising: a cover for the receiving chamber that is at least partially removable. ### Claim 8 (depends on 1) The bio-chamber according to claim 1, wherein the chamber body comprises a sea container or a shipping container. ### Claim 9 (depends on 8) The bio-chamber according to claim 8, wherein the sea container or shipping container has walls that are at least partially covered with stainless steel sheets; and the partition comprises at least one stainless steel sheet. ### Claim 10 (depends on 1) The bio-chamber according to claim 1, wherein the at least one air blower has a motor power of at least 0.75 kW, a pressure of at least 4200 Pa, and a volumetric flow rate of at least 9.5 cubic metres per minute for each 2.2 m3 of a mass contained in the receiving chamber, the mass having a height of 1.5 m. ### Claim 11 (depends on 1) A method of making organic fertilizer from poultry manure mixed with a carbon carrier, the method comprising: mixing the poultry manure with the carbon carrier;
