A method for carbon capture and recycling, the method including the steps of: (i) Capturing CO.sub.2 from at least one CO.sub.2 containing input; (ii) Producing a CO.sub.2 feed stream from the captured CO.sub.2; and (iii) Reacting the CO.sub.2 feed stream with a H.sub.2 feed stream to produce a methane containing output.

A method for recycling CO.sub.2 from CO.sub.2 containing inputs to produce hydrocarbon products includes the steps of (i) capturing CO.sub.2 from at least one CO.sub.2 containing input, at least one of the at least one CO.sub.2 containing input including air; (ii) producing a CO.sub.2 feed stream from the captured CO.sub.2; (iii) reacting the CO.sub.2 feed stream with a H.sub.2 feed stream to produce a methane containing output; and (iv) separating the methane containing output so as to at least provide methane and a first waste output, wherein the first waste output is incinerated or gasified to provide one of the at least one CO.sub.2 containing inputs for step (i).
