A historian of note had once observed that there is no such thing as a “natural” resource, rather there are only “potential” resources.
By way of example, the lumber and stones that were cleared on family farms here in Illinois were (at best) looked at as a temporary resource which quickly became an excess of lumber and rocks that had to be stacked for future use/sale, or in the case of the lumber – burnt to make way for farmable land.
In this sense the CO2 that could be (potentially) harvested, has gone from a waste material and pollutant, to becoming a resource that the manufacturers of CO2NCRETE would be willing to pay for (or receive for a nominal, free, or paid basis) in order to provide cheap building materials that can in turn, be sold for construction use.

“A UCLA research team has developed a plan for capturing carbon from power-plant smokestacks (the largest source of harmful global greenhouse gas in the world) and use it to create a new building material — CO2NCRETE — that would be fabricated using 3D printers while replacing production of cement (which creates about 5 percent of the planet’s greenhouse gas emissions).”
