    Abstract: Method for the utilisation of plastic wastes, which arise in the production, further processing or after use of the plastic, in that the plastic wastes, in a sewage treatment plant, are a) comminuted, then mixed with a sewage sludge to which organic flocculants are added and to which, if required, further amounts of finely divided charcoals and/or ashes are added, b) the plastic, if required, is modified in its surface properties by binders in such a way that it is better bound into the sludge, c) this pretreated sludge mixture is subjected to filtration, in which case the plastic can assume the properties of a filter aid, i.e. the reduction of the filter residue, d) the filter cakes obtained are burnt, in which case the plastic assumes the function of an additional energy source and e) the ash is deposited, for example, in a sanitary landfill or supplied for utilisation or a) comminuted if required b) and then mixed inside or outside a combustion furnace with a mixture, which has previously been subjected to filtration, of sewage sludge, organic flocculant and, if required, further amounts of finely divided charcoals and/or ashes, c) filtered again if required, d) the resulting mixture is burnt and e) the ash is deposited, for example, in a sanitary landfill or supplied for utilisation.
