4. Core Static Facts

• Implementing agency: Technology Development Board (TDB), a statutory body under DST, Ministry of Science & Technology [S1].
• Beneficiary: M/s MiniMines Cleantech Solutions Pvt. Ltd. [S1].
• Project title: "Sustainable Recycling of the Waste Lithium-ion Batteries" [S1].
• Outputs: battery-grade salts of Li, Co, Ni, Mn [S1].
• Process attributes: indigenous, zero-discharge, sustainable refining [S1].
• Parent policy umbrella: NCMM (₹16,300 cr, 7-yr) + ₹1,500 cr Recycling Incentive Scheme targeting 270 kt recycling capacity / 40 kt critical minerals / ₹8,000 cr investment / ~70,000 jobs [S2][S3].
• TDB enabling statute: Technology Development Board Act, 1995 (statutory body funding commercialisation of indigenous tech).

5. Multi-Dimensional Analysis

Economic - Reduces import dependence on Li, Co, Ni — currently >90% imported for EV/storage value chain [S2]. - Aligns with PLI-ACC (Advanced Chemistry Cell) scheme; supports downstream EV manufacturing cost competitiveness [S2].

Environmental - Zero-discharge process avoids hydrometallurgical effluents typical of conventional leaching [S1]. - Diverts hazardous Li-ion waste from landfill; supports EPR under Battery Waste Management Rules, 2022 (MoEFCC).

Scientific / Technological - Indigenous refining route demonstrates urban mining capability — recovering battery-grade salts (not just mixed oxides) signals high purity output [S1]. - Complements DST-TDB pattern of backing BatX Energies (earlier 2024 sanction) for similar recycling commercialisation [S1].

Strategic - Critical minerals are designated under Mines and Minerals (Development and Regulation) Amendment Act, 2023 which enabled central auction of 24 critical/strategic minerals [S2]. - Counters Chinese dominance in Li-Co-Ni midstream processing.

Administrative / Governance - Multi-ministry interface: DST (TDB funding), Mines (NCMM), MoEFCC (Battery Waste Rules), Heavy Industries (FAME/PLI-ACC).

6. Recent Developments (last 12-18 months)

• Jan 2025: NCMM approved by Union Cabinet [S2].
• 2025: ₹1,500 cr Recycling Incentive Scheme approved; eligible feedstock includes e-waste, LIB scrap, end-of-life vehicle parts [S3].
• 2025: 58 companies found eligible under the recycling scheme [S2].
• Budget 2025-26: customs exemption extended to Li-ion battery scrap, cobalt waste [S2].
• 06 Mar 2026: TDB sanction to MiniMines announced [S1].

7. Prelims Hooks

• TDB is a statutory body under DST, set up under the TDB Act, 1995 — not under MeitY.
• Project outputs: Li, Co, Ni, Mn battery-grade salts (manganese included) [S1].
• NCMM outlay: ₹16,300 cr over 7 years (2024-25 to 2030-31) [S2].
• Recycling Incentive Scheme outlay: ₹1,500 cr, tenure FY 2025-26 to 2030-31 [S3].
• Recycling Scheme target: 270 kt capacity, 40 kt critical minerals output, ~70,000 jobs [S3].
• India's critical mineral list has 30 minerals (Ministry of Mines, 2023) [S2].
• Union Budget 2024-25 removed customs duty on 25 critical minerals [S2].
• Budget 2025-26 exempted Li-ion battery scrap, cobalt powder/waste, lead, zinc + 12 more [S2].
• MMDR Amendment Act 2023 allowed Centre to auction critical/strategic minerals.
• Battery Waste Management Rules notified by MoEFCC in 2022 (EPR-based).
• 58 companies eligible under the recycling incentive scheme [S2].
• TDB earlier supported BatX Energies for similar Li-ion recycling tech [S1].

8. Mains Relevance

• GS-III: (a) Indian Economy — infrastructure, energy; (b) Science & Tech — indigenisation; (c) Environment — circular economy, waste management.
• GS-II: Government policies & interventions (NCMM).
• Probable stems: 1. "Securing critical mineral supply chains is integral to India's energy transition." Examine NCMM and recycling initiatives. 2. "Urban mining can substitute for primary extraction." Discuss with reference to Li-ion battery recycling in India. 3. Evaluate the role of statutory bodies like TDB in bridging the lab-to-market gap for indigenous clean technologies.

10. Common Errors / Trap Areas

• TDB is under DST (Min. of Science & Technology), NOT Ministry of Mines or MeitY.
• NCMM outlay is ₹16,300 cr (mission) — not to be confused with the ₹1,500 cr recycling scheme.
• Critical minerals list has 30 items (2023) — aspirants often cite 49 (that's the Geological Survey's list) or older figures.
• Battery Waste Rules are 2022, under MoEFCC — not under Ministry of Mines.
• MiniMines extracts battery-grade salts (Li, Co, Ni, Mn) — manganese is often omitted by aspirants.
• TDB Act year is 1995, not 1996.
