1. A method for processing rubber-based material comprising the steps of:
receiving rubber-based material;
loading the rubber-based material into one or more reusable trays;
pre-heating the rubber-based material in the one or more reusable trays using radiant heating in an oxygen depleted atmosphere to between about 100° C. to 250° C.;
processing the pre-heated rubber-based material by applying microwaves and further heat the pre-heated rubber material in the one or more reusable trays in an oxygen depleted environment until the pre-heated rubber is substantially reduced to a processed material comprising a carbonaceous material having a volatile content of below 5 wt %;
post-heating the processed material in the one or more reusable trays to more than about 400° C. using radiant heating in an oxygen depleted environment;
cooling the processed material in the one or more reusable trays to less than about 200° C. in an oxygen depleted environment; and
extracting the processed material from the one or more reusable trays.
