Zusammenfassung: | A process for the recovery of a complex of wastes is described, comprising waste oils and non-recyclable plastic materials, fed separately. According to the invention, the process provides at least a fractional distillation step of the waste oils as well as a devulcanisation step and a depolymerisation step of the vulcanised plastic materials with oil production, the mixing of the products of the fractional distillation of the waste oils and of the depolymerisation of the vulcanised plastic materials, and the subsequent hydrorefining of the mixture thus obtained. According to a preferred embodiment, the rubber powder which is discharged after the shredding step is mixed with the bitumen obtained from the fractional distillation of the waste oils, to give a rubber-powder-modified bitumen. According to a second aspect, there is also described a plant for the recovery of a complex of wastes which comprises a steam reforming area (1), a hydrorefining reactor (3), a fractional distillation column (7), and a "Plastbreaker" unit (9). |
