Absorbing large amounts of CO2 happens every second since 2-3 centuries at this point, and is the main driver of ocean acidification and subsequent coral bleaching, loss of wildlife, etc. If the mentioned process could "recycle" the CO2 needed for lime production, then it could be a big win for a very hard to decarbonize sector.

What is still to be checked is how more expensive this lime will be, and how it will stack up compared with traditional limestone+carbon tax

Price can be justified, if the government puts carbon tax on cement companies who dump large quantities of CO2 in the atmosphere.
