Vedanta Limited, Lanjigarh, India’s leading producer of metallurgical grade alumina, is supporting a slew of waste-to-wealth MSMEs in Odisha’s Kalahandi district. The company has supplied lime grit to local brick manufacturers, assisting in the transformation of industrial byproducts into value-added products for a circular economy.
Lime grit is a byproduct of refining bauxite (alumina ore) to produce alumina (or aluminium oxide, an intermediary product in the production of aluminium). It has a wide range of applications, including whitening paper, poultry feed, and even as a close substitute for gypsum.
Vedanta Lanjigarh produces approximately 10,500 metric tonnes of lime grit per year, nearly half of which is reused within the plant in various operations. Similarly, the production of thermal power within the company results in the formation of fly ash, another industrial byproduct. The company has been supplying both materials to local brick manufacturers to ensure maximum utilisation.
Mr. GG Pal, Dy. CEO – Alumina Business, Vedanta Limited, said of the initiative, “Our operations at Vedanta Lanjigarh are governed by the principles of Zero Waste and Zero Discharge.” We are bringing together environmental excellence and community development for true sustainability by developing circular economy value chains using industrial byproducts such as fly ash and lime grit. This initiative also encourages local communities’ entrepreneurial spirit, inspiring them to be active participants in the region’s development.”
