1. A method for recycling CO2 from CO2 containing inputs to produce hydrocarbon products, the method including the steps of:
(i) capturing CO2 from at least one CO2 containing input;
(ii) producing a CO2 feed stream from the captured CO2;
(iii) reacting the CO2 feed stream with a H2 feed stream to produce a methane containing output;
(iv) separating the methane containing output so as to at least provide methane and a first waste output;
(v) processing methane from the methane containing output to produce an acetylene containing output; and,
(vi) separating the acetylene containing output so as to at least provide acetylene and a second waste output,
wherein the first waste output is incinerated or gasified to provide one of the at least one CO2 containing inputs for step (i).
