C-Crete pours low-CO₂ concrete in NYC

The sustainable concrete start-up C-Crete Technologies has poured the first slab of its granite-based concrete, which will form the lobby floor in an upper story of JPMorgan Chase’s new global headquarters in New York City. C-Crete says that the production of the granite cementitious material emits no carbon dioxide, unlike conventional Portland cement, and that the concrete absorbs CO 2 from the air as it cures.
