Sodium bicarbonate serves diverse markets: food processing as a leavening agent and meat tenderizer, animal feed additive, pharmaceutical antacid and kidney-protection therapy, and industrial flue gas desulfurization via SDS dry injection. The SDS segment is expanding rapidly, especially in steel mills, coking plants, power stations, and waste incinerators, where ultra-fine grades (600-3200 mesh) are injected to remove SO2 and acid gases. However, coarse particles require on-site grinding to achieve d90 below 20 microns for effective reactivity, pushing some buyers toward pre-ground fine powder. In food and pharma, purity and particle consistency matter more than price, supporting premium segments. The medical use for chronic kidney disease metabolic acidosis is gaining clinical recognition, potentially boosting pharmaceutical-grade demand.
