01 Increasing Demand for Soda Ash in Glass Manufacturing Sodium carbonate, also known as soda ash, is an essential fluxing agent in the glass manufacturing process because it lowers the melting point of silica (sand), the main component of glass, making it more energy-efficient to melt and process. This reduces production costs and emissions. The growing demand for glass in a variety of industries, such as construction, automotive, and packaging, is driving the increased use of sodium carbonate and the growing trend of lightweight glass containers and vehicle windows, which calls for specialized glass compositions, also contributes to the industry's increased demand for soda ash. GHCL, which produces sodium bicarbonate and sodium bicarbonate, a key raw material for the glass manufacturing industry, is constructing a greenfield soda ash plant in the Kutch district's Mandvi Taluka, with a 5 lakh MTPA capacity with an investment of Rs 4,000 crore (USD 483.7 million) in May.
May 2026 Solvay expanded its sodium bicarbonate production capacity by upgrading manufacturing facilities to meet growing demand from food, pharmaceutical, environmental, and industrial applications.
March 2026 Tata Chemicals introduced high-purity sodium bicarbonate grades for pharmaceutical and food processing applications, strengthening its specialty chemicals portfolio.
October 2025 Tosoh Corporation expanded production of specialty sodium bicarbonate products to support environmental treatment, healthcare, and food manufacturing industries.
June 2025 Church & Dwight expanded manufacturing capacity for sodium bicarbonate products to support increasing demand across consumer, industrial, and healthcare markets.
