Eventually, these elements react with the CO 2 in the atmosphere to create new rocks like calcium carbonate and limestone, sequestering CO 2 in the process. Related Story.

Well, food-grade calcium carbonate, anyway; we suspect lime pulled straight out of a marine diesel's exhaust might not quite qualify there. Europe was buying industrial-grade lime for $340/tonne.

To make concrete, limestone, or calcium carbonate, is mixed with clay and other materials and then calcined at high temperatures, so CO2 is released via the thermal decomposition of calcium carbonate.
