Method for degradation of a plastic-containing waste

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;
• wherein the plastic comprises polylactic acid (PLA) or polybutyrate adipate terephthalate (PBAT);
• and
• wherein the bacteria belongs to the Geobacillus thermoleovorans or the Bacillus licheniformis.
