Abstract

The environmental consequences of global warming, and imminent regulation of industrial carbon dioxide (CO₂) emissions will be costly. Our objective is to develop a technology that may provide very low cost CO₂ mitigation in several small, but important niche markets. Specifically, we will i) measure the CO₂ sequestration capacity of inexpensive and readily available construction and manufacturing wastes including steel slag, concrete debris, and bauxite residue, ii) evaluate the primary geochemical reactions responsible for sequestering CO₂ in each waste, and iii) evaluate the economics of using process wastes to capture CO₂. Conclusions from this study will further understanding of the long-term CO₂ sequestration potential of these materials.
