Title: Method and apparatus for recycling thermoplastic containers
Inventor: SADR CHANGIZE
IPC: C08J11/06
Filed: 1991-03-18
Granted: 1993-07-06
Abstract: ABSTRACT OF THE DISCLOSURE            In general, used thermoplastic liquid containers such as oil and solvent bottles are discarded. When recycling oil bottles, the usual practice is to wash the bottles with a solvent to remove oil therefrom.  Washing of the bottles results in large quantities of used, oil-containing solvent, which present a disposal problem.  A simple solution to the problem of recycling liquid containers with no preliminary washing or cleaning operation includes the steps of tumbling the bottles to promote liquid separation, shredding the bottles into small pieces and draining the liquid therefrom, grinding the pieces of plastic to yield a particulate thermoplastic, and mixing the particulate thermoplastic and any liquid remaining therein with an additive, e.g. an oil absorbent and a filler such as calcium carbonate, glass, mica or talc , and when the liquid is an oil, an absorbent to produce an extrudable mixture which can be used to form new containers.
