Asia holds 79% of the world’s cement production capacity, and that concentration ripples through every downstream lime market decision from kiln fuel choices to FGD reagent costs. At the same time, lime average export unit value for 2022 lands at $?? per tonne, creating a sharp question for buyers as energy and carbon prices swing. Put these pressures next to applications that range from SO2 control and water softening to soil stabilization and steelmaking flux, and suddenly “lime demand” stops being a single line item.
