Working to upend one of the most stalwart of construction materials, a team of UCLA engineers, scientists and policy experts has advanced to the finals of the $20 million NRG COSIA Carbon XPRIZE by successfully creating a version of concrete that is nearly carbon-dioxide-neutral.

The international competition, which began in 2015 and is scheduled to conclude in 2020, challenged teams to develop carbon technologies that convert carbon dioxide emissions from power plants and industrial facilities into viable products. The eco-friendly building material, called CO2NCRETE, was developed by the UCLA Carbon Upcycling team and offers similar strengths and functionality as traditional concrete.

Ten finalists have been selected from a field of 27 semifinalists by an independent judging panel of eight international energy, sustainability and carbon dioxide experts. The teams have been awarded an equal share of a $5 million milestone prize.

“As the son and grandson of civil engineers, I have always been fascinated by construction, and reaching the XPRIZE finals by doing what I am most passionate about is perfectly aligned with what I value,” said Gaurav Sant, professor of civil and environmental engineering and of materials science in the UCLA Samueli School of Engineering. “The concrete and construction industries are ripe for disruption and the ability to make a positive impact in these sectors, while lessening our carbon dioxide footprint, is a worthy cause for the entire UCLA team.”
