1. A method of producing a lubricant comprising:
exposing, at a temperature of 150-350° C. and a pressure of 100-200 psi for 12-72 hours, a plurality of polymer molecules to a catalyst comprising a substrate having a plurality of catalytic nanoparticles deposited thereon;
cleaving at least one carbon-carbon bond of a first polymer molecule of the plurality of polymer molecules;
forming a plurality of hydrocarbon fragments from the cleaving;
cleaving at least one carbon-carbon bond of a second polymer molecule of the plurality of polymer molecules; and
forming a second plurality of hydrocarbon fragments.
