On National Technology Day 2025, Vedanta Aluminium announced a patent for its breakthrough tech that recovers 99 per cent pure graphite from aluminium waste, aligning with this year’s theme, YANTRA, by turning waste into a strategic resource.
Vedanta’s solution recovers usable graphite from aluminium industry waste, turning a challenge into a resource. This method showcases Indian industry’s deep-tech capabilities, supporting missions like Atmanirbhar Bharat, Critical Minerals and Net Zero goals.
Vedanta Aluminium’s in-house R&D team, with CSIR-IMMT Bhubaneswar, developed the patented process to extract battery-grade graphite from aluminium waste like Spent Pot Lining and Shot Blast Dust. This supports India’s circular economy goals and can reduce over 70 per cent dependence on imported graphite.
The newly developed technology aligns with Vedanta's broader vision to strengthen India’s technology and engineering sectors. On the same day, the Group reaffirmed this commitment and announced plans to boost the production of transition metals and value-added products. In line with this focus, Vedanta is moving forward with the expansion of its aluminium and zinc product portfolios. According to the report, the company has already approved a total investment of USD 105 billion to enhance the capacity of both primary aluminium and value-added aluminium products at its flagship production facilities.
Recovered graphite has applications in multiple industries, including lithium-ion batteries, lubricants and brake linings. With demand for electric mobility growing, this recovered material could support the battery supply chain. The process also aligns with circular economy principles by repurposing waste.
Rajiv Kumar, CEO of Vedanta Aluminium, said, “With India’s demand for electric vehicles, energy storage, and high-tech electronics set to skyrocket, our patented solution is both timely and transformative. It strengthens our contribution to India’s critical minerals roadmap while advancing our vision of zero-waste, future-ready manufacturing.”
In 2024, India imported around USD 41 million in natural graphite, ranking among Asia-Pacific’s top importers. Vedanta Aluminium’s graphite recovery technology offers a path to reduce this reliance and supports national goals for self-reliance in critical minerals.
