Abstract
One embodiment of a method of recycling a plastic material includes heating a plastic material in a treatment chamber in incremental steps through a series of graduated temperature set points wherein each graduated temperature set point corresponds to a vaporization temperature of an individual by-product of said plastic material, and pulling a vacuum of inert gas on the treatment chamber at each temperature set point to selectively remove an individual by-product corresponding to the temperature set point.
Claims20
A method of recycling a plastic material, comprising:
- heating a treatment chamber including a plastic material to a first predetermined temperature;
- pulling a vacuum on said treatment chamber to remove a first gaseous product from said plastic material;
- heating said treatment chamber to a second predetermined temperature greater than said first predetermined temperature;
- and
- pulling a vacuum on said treatment chamber to remove a second gaseous product from said plastic material.
A system for recycling plastic material, comprising:
- a treatment chamber for receiving plastic material therein;
- a heating system that heats said treatment chamber;
- a vacuum system that pulls a vacuum on said treatment chamber utilizing an inert gas;
- and
- a control system including computer operable instructions that control said heating system to heat said treatment chamber in incremental steps through a series of graduated temperature set points.
