CARBON SEQUESTRATION THROUGH THE PRODUCTION OF

per year. Waste cement is a suitable source material for PCC production via mineral carbonation and can be recovered from waste concrete as a byproduct of aggregate recycling practices. The objective of this research was to investigate the possibility of sequestering CO 2 by producing PCC via the recovery and carbonation of waste cement calcium.
