Accelerated weathering of limestone for CO<sub>2</sub> mitigation: Opportunities for the stone and cement industries

Langer, W. H.; San, Juan, C. A.; Rau, G. H.; Caldeira, K.

Abstract:

Accelerated weathering of limestone appears to provide a low-tech, inexpensive, high-capacity, environmentally friendly CO₂ mitigation method that could be applied to about 200 fossil fuel fired power plants and about eight cement plants located in coastal areas in the conterminous U.S. This approach could also help solve the problem of disposal of limestone waste fines in the crushed stone industry. Research and implementation of this technology will require new collaborative efforts among the crushed stone and cement industries, electric utilities, and the science and engineering communities.
