    Green pulp mill: Renewable alternatives to fossil fuels in

    The lime kiln in a kraft pulp mill converts lime mud, which is largely composed of calcium carbonate (CaCO 3), into burnt lime, i.e., calcium oxide (CaO), and carbon dioxide (CO 2). This thermal decomposition reaction requires a high temperature and occurs spontaneously when the lime mud temperature exceeds approximately 800 C in a gas
