1. A method for a thermomechanochemical (TMC) waste treatment via a TMC waste treatment system, wherein the TMC waste treatment system includes a controller, comprising:
feeding a waste material to a TMC chamber from one or more containers housing the waste material in one or more of a liquid-solid state, a semi-wet or slurry solid state, and a dry solid state;
processing the waste material at the TMC chamber by milling at elevated temperatures in a presence of co-milling reagents including, via the controller setting an operation temperature of a heater in a range of 160° F. to 650° F., setting a heat duration in range of 6 hours, setting a milling speed in range of 30 revolutions per minute; and
removing byproducts obtained after processing of the waste material from the TMC chamber, including removing solid and semi-solid byproducts via a disposal system and removing gaseous byproducts via an emissions control module.
