Title
(EN) METHOD FOR DEGRADATION OF A PLASTIC-CONTAINING WASTE
(FR) PROCÉDÉ DE DÉGRADATION DE DÉCHETS CONTENANT DU PLASTIQUE
Abstract
(EN) 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.
(FR) La présente invention concerne un procédé de dégradation de déchets contenant du plastique comprenant en outre des déchets végétaux et/ou animaux cellulosiques, le procédé comprenant le mélange des déchets contenant du plastique avec une composition comprenant des bactéries en présence d'air, les déchets contenant du plastique étant introduits jusqu'à un niveau prédéfini dans un appareil de digestion comprenant un réservoir allongé ayant un ou plusieurs arbres de mélange rotatifs dotés de pales d'agitation s'étendant radialement fixées aux arbres, les déchets contenant du plastique ayant un rapport surface/volume d'au moins 1,1 lorsque l'appareil de digestion est rempli jusqu'au niveau prédéfini, la surface étant ainsi la surface en m2 des déchets contenant du plastique introduits jusqu'à l'interface d'air et le volume étant ainsi le volume des déchets contenant du plastique en m3.
