Abstract
A method of treatment of wood ash residue. A first step involves wetting the wood ash residue. A second step involves reacting the wetted wood ash residue with carbon dioxide gas. Mineral oxides and hydroxides are converted to carbonates, thereby reducing the caustic nature of the wood ash residue. A third step involves continuing to react the wetted wood ash residue until the resulting ash residue is substantially carbonated.
