Our Process
- The reverse logistics operation employs a HUB & SPOKE model, allowing us to acquire end-of-life Lithium-ion cells from a wide range of locations (SPOKE) and transport them securely and effectively to our main recycling facility (HUB).
- Battery sources - We responsibly and ethically secure our inventory of used Li-ion cells from diverse sources, including electronics, electric vehicles, and other devices, with a steadfast commitment to safety. While our current procurement primarily focuses on India, we remain receptive to the potential of sourcing from international locations in the future.
- Harnessing Technology - We employ cutting-edge technologies including Artificial Intelligence, Machine Learning, and Blockchain to continually enhance our efficiency, safety measures, raw material quality, and consistency.
Segregation and Dismantling process
- Testing:
- Visual inspection:
Batteries are visually inspected for any exterior damage or deformities. - Voltage testing:
Each battery is tested to measure its voltage output to check for any significant deviations.
- Visual inspection:
- Sorting:
- Sorting by type:
Batteries are sorted based on their chemistry (e.g., lithium cobalt oxide, lithium iron phosphate) and form factor (e.g., cylindrical, prismatic).
- Sorting by type:
- Dismantling:
- Manual dismantling:
Skilled technicians disassemble the batteries carefully, removing the outer casing and separating the internal components.
- Manual dismantling:
- Shredding: The batteries are fed into a shredding machine equipped with sharp blades that tear the batteries apart into smaller pieces. The shredded materials, which include electrodes, electrolytes, and casings, are collected for further processing.
- Crushing: Secondary crushing: The shredded materials are further processed in a crushing machine to reduce their size into smaller fragments. In some cases, the crushed materials are further pulverized into fine powder to facilitate the separation of different components.
- Separation of Components: Mechanical separation: Techniques such as sieving and magnetic separation are utilized to separate metal components (e.g., foils) from the powdered mix. Sieving: The fine powder is passed through sieves to separate the different components based on particle size.
- Recovery of active materials: Processes such as hydrometallurgical or pyrometallurgical methods are employed to extract valuable metals such as cobalt, nickel, and lithium from the recovered materials.
- Recovery of other components: Plastics and other non-metallic materials are also recovered for potential reuse or further recycling.
