Abstract: The system is based on a recirculating Carbon Flow Loop, within which toxins in municipal waste or other feedstock are neutralized in a plasma reactor, by using an electric arc in ionized gas to generate ultra high temperatures. This breaks down substances into their basic molecules, and transforms the feedstock into syngas (which is comprised predominantly of hydrogen and carbon monoxide). This can be processed by a water shift reactor, an engine driven electric generator or another exothermic device where carbon monoxide is transformed into carbon dioxide. This continues flowing in the carbon loop to an Algae Bioreactor. Here photosynthesis of the algae transforms the carbon dioxide to become part of an oil rich carbohydrate. This can either continue to the next stage as feedstock and recirculate again around the Carbon Loop and/or exit, and be used to manufacture biofuel or other substances.
