Abstract: A hog waste processing apparatus is comprised of standard hog barns which are fluidly connected to separators. The separators are fluidly connected to a pair of reactor cells. The reactor cells are filled with EcoBlocks to increase the surface area upon which biological reactions occur. Excess fluid from the reactor cells drains into a polishing cell which recycles the water to flush the barns. A method is also affiliated with the apparatus. The method comprises flushing the barns with water once a week to remove animal waste to the separators. Once a month the separator being used is allowed to completely dry and the solid waste is removed to a storage area for further drying and shipment.
