ABSTRACT:
The present invention is a process for separating granulated plastic oil containers from the oil residue remaining within the containers after use. In this process, the plastic oil container is granulated prior to the separation of the oil from the plastic; the subsequent separation is done mechanically without washing or solvent deployment. The system comprises a conveying system, a size reduction means operating in conjunction with a centrifugal separation apparatus, and a means of segregating and storing the separated oil and the plastic granulate. In a first embodiment, the process is employed as a truck mounted unit for mobile processing of oil containers at the location of utilization. In a second embodiment, the process is employed as stationary processing facility.
