Herein, originally from Italy, though housed in the USDOE's National Laboratory library, we present a discussion about the productive recycling of Carbon Dioxide, as might originate in an industrial process utilizing Coal.
The premise, in confirmation of other documentation attesting to CO2 recycling potentials we have already provided you, is that CO2 can be used as a "substitute" raw material, in place of other chemicals, such as the highly-toxic Phosgene (aka: Mustard Gas), in the manufacture of useful, and common, plastics.
And, as interesting as such practical use of CO2 might be, these Italian scientists make a point that, due to the awkwardness of translation, might be missed:
Not only can Carbon Dioxide be productively utilized in place of other, some highly-toxic, materials, such practical use of Carbon Dioxide prevents the generation of more Carbon Dioxide in the commercial manufacture of those other raw materials.
Such co-generated CO2 arises both from the chemical reactions that synthesize those other plastics raw materials, and, potentially, indirectly, from the generation of the power needed to drive those reactions.

Abstract: The reduction of carbon dioxide emission requires the implementation of several convergent technologies in different production sectors. The chemical industry can contribute to the issue with innovative synthetic technologies, that implement the principles of atom-economy, dematerialisation, energy saving, and raw material diversification with carbon recycling. The innovative synthetic methodologies merge the issues of avoiding the production of CO2 and carbon recycling, through carbon dioxide utilisation. In this paper, some options will be discussed, namely the synthesis of carboxylic acids, organic carbonates, and carbamatedisocyanates.
The synthesis of methanol from CO2 and CO will be compared.
Introduction: The implementation of innovative synthetic technologies based on CO2 can considerably
contribute to the reduction of carbon dioxide emission. The avoided amount is not simply represented by the amount of CO2 fixed. As we have already discussed, the assessment of the exact amount of avoided CO2 requires an integrated approach which takes in consideration several parameters ... .

New synthetic methodologies that implement the principles of atom economy, solvent shift, waste minimization at source, use of less noxious materials and carbon recycling, contribute to CO2 reduction in many different ways ... .
The use of carbon dioxide is a better option with respect to both phosgene and carbon monoxide.
CO2 can be recovered from industrial plants, responding, thus, to the principle of recovery and recycling, and to the international agreement of reducing greenhouse gases emission. This goal is met not only for the recycled fraction of carbon dioxide, but also, and essentially, for the avoided use of natural resources, necessary for the synthesis of carbon monoxide or phosgene, and, the reduced production of waste."
----------
Again, as in the passage immediately above, not only can effluent Carbon Dioxide be utilized, in accordance with "the principle of recovery and recycling", instead of highly toxic chemicals, such as phosgene, in the manufacture of plastics raw materials such as "carbonates, and carbamatedisocyanates", that CO2 utilization also conserves other "natural resources" and reduces "production of waste".
And, that other "waste", production of which is reduced through the utilization of Carbon Dioxide, as revealed in the full report, does include Carbon Dioxide, as in "avoided CO2".
Moreover, the Carbon Dioxide consumed in the synthesis of plastics raw materials would be chemically, and thus permanently, sequestered within those plastics.
Finally, we must again, almost by now gratuitously, note:
These Italian scientists confirm for us one more time that we can synthesize Methanol from Carbon Dioxide. And, once we have that Methanol, we can, by using, for one instance, ExxonMobil's "MTG"(r) process, convert it into Gasoline.
