Production of Carbonates by Carbon Recycling

Abstract

The mineral carbonation technology in which carbon dioxide (CO₂) is converted into stable carbonates using alkaline waste and byproduct is one of the carbon recycling technologies and is attracting attention for its early social implementation. In this article, calcium carbonate (CaCO₃) production from concrete sludge, demolished concrete, and fly ash by wet indirect carbonation technologies is introduced. The all investigations introduced are aiming for the development of efficient processes only consume CO₂ for CO₂ conversion in the processes. The mineral carbonation is an important technology for the proper treatment of various types of alkaline waste and byproduct and for establishing Ca/CO₂ circulation.
