US: A team from the University of Colorado Boulder (UCB) has developed a carbon-neutral alternative cement from biogenic limestone. The limestone comes from farmed cocolitophores, which capture CO2 as they grow.
The UCB scientists collaborated with colleagues from the University of Carolina at Wilmington and the National Renewable Energy Laboratory on the project. Their work has received US$3.2m in US Department of Energy funding.
