The use case for all of these CO2 reduction methods that seems particularly interesting is if you capture the CO2 inevitably produced as a byproduct of cement production and then convert it into useful plastics. You avoid air capture and you get something that's good for more than just burning.

We have so much plastic, I almost wonder if it would be easy enough to burn it, capture the CO2, and convert that into new plastic.

Scalable CCU at source in cement production would be great at getting the 8% or so of global emissions related to cement production down somewhat. Other ways of tackling cement production related emissions are less CO2 producing alternatives to clinker, and even reusing old concrete panels in new construction. There are many rational, viable paths to address this, and other CO2 emission sources - but as long as CO2 emissions don’t have a cost associated, incentives to research, scale and push alternatives forward are lower than to keep doing what we’re doing
