Lanjigarh Alumina: Higher Productivity through Improved Operational Practices
The company has attributed increase in production to significant improvement in operating efficiencies.
Lanjigarh alumina refinery has achieved 9% reduction in bauxite cost per tonne through strategic bauxite sourcing. Under an agreement with government of Odisha, Lanjigarh refinery is purchasing 70% of bauxite mined by Odisha Mining Corporation. The refinery has reduced its reliance on bauxite imports to about 10% which was 39% in FY19. This has, in turn, helped to refine alumina in a more efficient and time-effective manner.
The plant has also ramped up production by reducing consumption of caustic soda by 26% in comparison to last year. It is also building a caustic soda plant in Dharma, Odisha with an investment of INR 6,500 crore to increase captive capacity.
Through plant automation and process improvement, refinery has registered a 19% decline in conversion cost of bauxite to alumina.
Amendments have also been made in logistics by shifting from road to rail transport. In addition improvement in operating parameters at Lanjigarh, in-house power plant has brought down fixed cost and reduced its carbon emission intensity to 30% below global averages of other alumina refineries.
Lanjigarh alumina refinery is now among top 5 alumina refineries globally in terms of total energy consumption.
