NOVELTY - Converting relatively low value carbonaceous feedstock into relatively high value chemical product comprises: introducing relatively low value carbonaceous feedstock into inductively coupled plasma (ICP) torch based reactor under conditions to generate synthetic gas mixture having specific composition; introducing synthetic gas mixture into microbial bioreactor configured to convert synthetic gas mixture into relatively high value chemical product, where specific composition of synthetic gas mixture is based on needs of microbial bioreactor; and collecting high value chemical product.    USE - The method is useful for converting relatively low value carbonaceous feedstock (including biomass) into relatively high value chemical product, preferably converting carbon dioxide emissions into a relatively higher value chemical product including ethanol, acetate, pharmacologically valuable compound, pharmacologically active compound and amino acid (all claimed).    ADVANTAGE - The method: reduces or eliminates carbon dioxide emissions in industrial processes, while generating useful chemical products; is economical as it requires modest capital investment in the ICP reactor and digester, less operating costs and less electrical power; reduces or eliminates expenses associated with managing carbon dioxide emissions; has ability to rapidly adjust the quantity and quality of the synthetic gas mixture produced in response to changes in the downstream microbial digesters; has ability to operate at variable power inputs, to optimize the production of a synthetic gas mixture, thus achieving maximum operational efficiency; and easily produces synthetic gas mixtures without the need for the removal of contaminants including sulfur from the feedstock.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for:    (1) a system for converting a relatively lower value carbonaceous feedstock into a relatively higher value chemical product, comprising (a) an inductively coupled plasma reactor configured to generate a synthetic gas mixture having a tailored composition, and (b) a microbial digester configured to convert the synthetic gas mixture into the relatively higher value chemical product;    (2) a system for converting carbon dioxide emissions into a relatively higher value chemical product, comprising (a1) IPC reactor configured to generate a tailored synthetic gas mixture from the carbon dioxide emissions and a carbonaceous feedstock, (b1) a bio-reactor configured to convert the tailored synthetic gas mixture into the relatively higher value chemical product, and (c1) a controller configured to implement the function of controlling the ICP reactor such that a quantity and composition of the synthetic gas mixture produced corresponds to the needs of the bio-reactor; and    (3) converting carbon dioxide emissions into a relatively higher value chemical product, comprising introducing the carbon dioxide emissions and a carbonaceous feedstock into ICP reactor under conditions to generate a synthetic gas product, introducing the synthetic gas mixture into a bio-reactor configured to convert the synthetic gas mixture into the relatively higher value chemical product, and collecting the relatively higher value chemical product.
