The TDB of the DST has approved funding for MiniMines Cleantech Solutions Pvt. Ltd. to set up a commercial plant for the sustainable recycling of end‑of‑life lithium‑ion batteries.
Key Developments
- Financial support extended to scale up the “Sustainable Recycling of the Waste Lithium‑ion Batteries” project.
- Commercialisation of an indigenous, zero‑discharge Hybrid Hydrometallurgy™ technology.
- Target recovery rates of up to 99 % for battery‑grade salts such as lithium carbonate and cobalt sulphate.
- Integration of EPR services for lithium‑ion batteries.
- Alignment with the National Critical Minerals Mission and the broader Aatmanirbhar Bharat agenda.
Important Facts
The company’s end‑to‑end recycling chain covers pre‑assessment, collection, segregation, mechanical processing, and advanced post‑processing stages such as selective separation and beneficiation. All steps are patented and developed domestically, reducing reliance on imported recycling equipment. The recovered materials will meet industry specifications and cater to both domestic demand and export markets, thereby supporting India’s clean‑energy transition.
UPSC Relevance
Understanding this initiative is crucial for GS III (Economy & Environment) as it illustrates:
- How India is building strategic autonomy in critical mineral supply chains.
- The role of public‑private partnerships and government funding mechanisms like TDB in technology commercialization.
- The practical application of circular‑economy concepts and EPR policies in the electronics sector.
- Implications for energy security, given the dependence of electric‑vehicle and renewable‑energy storage on lithium‑ion batteries.
Way Forward
To maximise impact, the government should:
- Facilitate a robust regulatory framework for battery collection and recycling under the EPR mandate.
- Encourage scaling of similar indigenous technologies through additional grants and tax incentives.
- Promote research‑driven innovation in alternative recycling methods to further lower energy consumption and emissions.
- Integrate recovered critical minerals into domestic manufacturing clusters for batteries and renewable‑energy storage, reducing import bills.
Successful implementation will strengthen India’s position in the global clean‑technology landscape while advancing the goals of self‑reliance and sustainable development.
