Environmental performance of MICP through ureolytic bacteria, using laboratory-grade and commercial-grade chemicals, against the manufactured calcium carbonate (Porter et al., 2021)
| Carbonation process | Carbon dioxide emission: carbon dioxide/kg calcium carbonate | Energy consumption: MJ/kg calcium carbonate |
|---|---|---|
| Manufactured calcium carbonate | 2.37 | 7.2 |
| MICP through ureolytic bacteria (using laboratory-grade chemicals) | 2.06 | 28.4 |
| MICP through ureolytic bacteria (using commercial-grade chemicals) | 1.51 | 16.1 |
| Carbonation process | Carbon dioxide emission: carbon dioxide/kg calcium carbonate | Energy consumption: MJ/kg calcium carbonate |
