A Competitive And effiCient Lime industry
limestone. When heated, a chemical reaction takes place where limestone is transformed into lime and CO 2 is released. These process emissions are inevitable and fairly constant per tonne of lime. Unless the carbon is captured, and used or stored, but its economic feasibility has to be looked at. Lime is enabling key material for many sectors.
