A system and a method for processing plastic, and plastic processed therefrom

A system for processing plastic wherein, in use, the system is adapted for the frictional heating of the plastic, the system comprising:

• a frictional heater adapted in use to bear against the plastic;
• wherein the frictional heater is substantially cylindrical and comprises a plurality of molten plastic conduits arranged radially and substantially perpendicular an axis of rotation of the frictional heater;
• the plurality of molten plastic conduits being adapted to allow molten plastic to enter substantially within the cylinder;
• and
• wherein the frictional heater is configured to allow molten plastic to flow from within the frictional heater under gravity.

A method for processing plastic including the frictional heating of the plastic, the method comprising:

• providing a substantially cylindrical frictional heater comprising a plurality of molten plastic conduits arranged radially and substantially perpendicular an axis of a rotation of the substantially cylindrical frictional heater;
• providing at least one pusher adapted to bear the plastic against the substantially cylindrical frictional heater in a direction substantially perpendicular to the axis of rotation of the substantially cylindrical frictional heater;
• depositing plastic feedstock into a chamber adapted to confine the plastic feedstock, the plastic feedstock optionally comprising one or more non-plastic contaminants;
• with the at least one pusher, pushing the plastic feedstocks into engagement with an outer periphery of the substantially cylindrical frictional heater in a direction substantially perpendicular to an axis of rotation of the substantially cylindrical frictional heater;
• substantially melting the plastic feedstock by frictional engagement with the substantially cylindrical frictional heater and allowing substantially molten feedstock to flow through the plurality of molten plastic conduits to substantially within an interior of the substantially cylindrical frictional heater to perform intimate mixing of plastic types and the one or more non-plastic contaminants and causing the one or more plastic contaminants to be finely dispersed throughout the molten mass.
