Abstract: The invention is directed to a process to bacterially decompose organic waste, material to a digested material in a digesting tank by mixing the organic waste material with aerobic bacteria at a temperature of between 40 C and 70° C. while supplying between 0.5 and 10 m3 of air per hour per kg of the total of organic waste material on a dry basis and digested material on a dry basis and discharging from the digesting tank a humid air stream.

Abstract: The present invention relates to a method for degradation of a plastic-containing waste further comprising cellulosic, plant and/or animal waste, the method comprising mixing the plastic-containing waste with a composition comprising bacteria in the presence of air wherein the plastic containing waste is filled to a predetermined level in a digesting apparatus comprising of an elongated tank having one or more rotating mixing shafts provided with radially extending agitating blades fixed to the shafts, wherein the plastic containing waste has a surface-to-volume ratio of at least 1.1 when the digesting apparatus is filled to the predetermined level, whereby the surface area is the surface area in m2 of the filled plastic containing waste to air interface, and the volume is the volume of the plastic containing waste in m3.

Abstract: The invention is directed to a process and equipment for use in a process to bacterially decompose organic waste to a dry composted end material wherein organic waste is composted in a composting tank in the presence of oxygen and aerobic bacteria to obtain a wet composted material. The wet composted material is partly removed from the composting tank and dried such to lower the water content of the composted material to obtain dry composted end material.
