A new system developed by UCLA researchers captures carbon from smokestacks and processes the C02 into a new building material that could replace concrete. The tiny cones of the "CO2NCRETE" material are fabricated using 3D printers.

“What this technology does is take something that we have viewed as a nuisance — carbon dioxide that’s emitted from smokestacks — and turn it into something valuable,” said J.R. DeShazo, professor of public policy at the UCLA Luskin School of Public Affairs and director of the UCLA Luskin Center for Innovation.

The UCLA team demonstrated a process of combining lime with carbon dioxide to produce the cement-like material.
