2. MeitY transfers cost effective Li-ion battery recycling technology to nine recycling industries and start-ups
Topic: GS3 – Science and technology.
Context:
-
-
-
The Ministry of Electronics and Information Technology (MeitY) has transferred cost-effective Li-ion battery recycling technology to nine recycling industries and start-ups.
-
-
Issue:
-
-
-
The technology, developed under the Mission LiFE initiative, can process various types of discarded Li-ion batteries and recover over 95% of Lithium, Cobalt, Manganese, and Nickel contents in the form of oxides/carbonates with about 98% purity.
-
The recycling process involves leaching and selective extraction of metal values through solvent extraction.
-
The secondary raw materials obtained from the recycling process can be used for battery manufacturing or other applications.
-
The technology was developed at the Centre of Excellence on E-waste Management, established at the Centre for Materials for Electronics Technology (C-MET) in Hyderabad in collaboration with the Government of Telangana and Greenko Energies Pvt. Ltd.
-
The initiative aligns with the circular economy goals set by NITI Aayog, and MeitY is leading in showcasing the outcomes of technology development in this area.

3. Government commits to increase availability and accessibility of better veterinary health services to minimise economic losses due to animal diseases
Topic: GS3 – Animal Husbandry
Context:
-
-
-
The Union Minister of Fisheries, Animal Husbandry and Dairying, Shri Parshottam Rupala, chaired an Inter-Session Meeting of the Consultative Committee attached to his Ministry in Srinagar.
-
-
Issue:
-
-
-
The Committee discussed the strengthening of veterinary services through mobile units and the implementation of vaccination programs in the country.

4. Researchers devise a low-cost method to secure long-distance communication by overcoming distortions
Topic: GS3 – Science and technology.
Context:
-
-
-
Scientists at the QuIC lab at the Raman Research Institute have developed a method to achieve secure long-distance communication without the need for costly active-polarization tracking devices.
-
-
Issue:
-
-
-
The method overcomes distortion due to photon-polarization caused by satellite movement and scrambling of polarization in optical fibers.
-
The approach utilizes novel optimization methods to achieve a trade-off between key rate, quantum-bit-error-rate (QBER), and key symmetry.
-
The method is cost-effective and eliminates the need for additional resources, making active polarization tracking devices unnecessary.
-
The entangled state used in the method has a high fidelity of 94%, and the protocol’s performance remains unchanged even with lower fidelities.
-
The optimization methods employed maximize the key rate while keeping the QBER below the secure threshold and ensuring balanced key symmetry.
