1. A method for converting an electric and/or electronic waste source to a Clean Fuel Gas source and Char source comprising:
inputting an electric and electronic waste source into a thermolysis system to generate a Clean Fuel Gas source and Char source;
wherein the thermolysis system comprises at least two reactors, an oil/water separator, an oil/tar cracker, and a gas scrubber;
wherein the reactors generate oils and tars;
wherein all of the oils and tars are separated in the oil/water separator and gas scrubber,
thereafter cracked in the oil/tar cracker, and sent to the secondary reactor to generate the Clean Fuel Gas source;
wherein the Clean Fuel Gas source is used for power to a system or application;
wherein the Char source contains recoverable metals; and
wherein the Clean Fuel Gas source and Char source are substantially-free of halogenated organic compounds and do not contain oils and/or tars.
