1. An integrated system for converting gaseous carbon compounds to carbon neutral or negative products, the system comprising:
one or more units that produce respective reactants;
one or more sources of carbon dioxide and methane;
a biological methane processing system containing methane metabolising microorganisms and fed with methane from the one or more sources, and one or more of the reactants, wherein the biological methane processing system:
propagates methane metabolising microorganisms; and
produces carbon dioxide as a by-product;
a biological carbon dioxide processing system containing carbon dioxide metabolising microorganisms and fed with carbon dioxide from the one or more sources, the carbon dioxide by-product, and one or more of the reactants, wherein the biological carbon dioxide processing system propagates carbon dioxide metabolising microorganisms;
a microorganism harvesting and processing system that:
harvests the methane metabolising microorganisms propagated by the biological methane processing system;
harvests the carbon dioxide metabolising microorganisms propagated by the biological carbon dioxide processing system; and
produces a single cell protein; and
a control system that controls flow of the carbon dioxide, methane and the reactants to the biological methane processing system and the biological carbon dioxide processing system to provide mass balanced quantities of the carbon dioxide and methane and reactants for processes performed in each of the biological methane processing system and the biological carbon dioxide processing system.
