14 Claims

1. An integrated process comprising:

a. processing a carbon black process feedstock in a carbon black process to generate a carbon black stream and at least a first secondary product stream comprising carbon dioxide, hydrogen, or both;

b. processing at least one material comprising carbon atoms, in a gasification process, to produce:

i. a raw syngas steam comprising at least carbon monoxide and carbon dioxide, and

ii. a first byproduct stream comprising a component selected from a metal, metal oxide, silica, steel, and/or char;

c. passing at least a portion of the raw syngas stream and at least a portion of the first secondary product stream to a gas fermentation process comprising a bioreactor containing a C1-fixing microorganism in a liquid nutrient medium to produce at least one fermentation product; and

d. providing the at least a portion of the carbon black stream and at least a portion of the at least one fermentation product to a downstream operation to produce tires.
