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 m.sup.2 of the filled plastic containing waste to air interface, and the volume is the volume of the plastic containing waste in m.sup.3.

A field in-place film-covering fermentation device is provided. The device includes a support structure, a covering film, and a ventilation structure. The support structure is connected to the covering film through cross-connecting rings on the covering film to form a columnar pile structure. The covering film is in a split configuration to form an upper surface, a lower surface, and a side elevation of the columnar pile structure by cutting. The ventilation structure is fixed in the columnar pile structure. The device can realize the in-place and nearby treatment of organic wastes, improve the material conversion efficiency of agricultural organic wastes in their production area, and promote the improvement of the regional ecological environment.
