These are some examples of ways to use things like concrete - something that normally produces CO2 - and engineer it so that uses CO2 as a building material.

Brent said that for every one ton of portland cement produces one ton of CO2. It inspired him to look for solutions elsewhere and he found it in nature - in the coral reef.

Calera makes materials that sequester the CO2 from the atmosphere; cementitous materials that could replace the typical portland cement.
