As the electric vehicle (EV) sector experiences explosive growth, demand for batteries skyrockets, leading to a significant increase in used batteries requiring recycling in the coming years.
Expanding renewable energy installations, which also rely on battery storage solutions, further contribute to this surge in battery demand and subsequent recycling needs.
Fortunately, government initiatives like the Battery Management Rules 2016 and the FAME-II scheme promote responsible battery disposal and recycling, creating a supportive environment for businesses entering this crucial field.
If you’re interested in joining the recycling industry, then his article will guide you through some key points you need to know before starting your own battery recycling business.
1. Types of Batteries Available for Recycling in India
Several types of batteries can be recycled in India. Here are some of the most common:
Lithium-ion batteries: The rising popularity of electric vehicles has created a significant potential for recycled lithium-ion batteries. While the technology for recycling Li-ion batteries is still evolving, there is a strong demand for recycled materials.
Lead-acid batteries: These are the most widely used batteries in non-electric vehicles in India. Their recycling processes are well-developed and offer high recovery rates for lead and other materials.
Nickel-metal hydride (NiMH) batteries: Used in some electronics and hybrid vehicles, NiMH batteries contain valuable nickel and rare earth metals but require specialized processing for recycling.
Alkaline batteries: Recycling these batteries is less profitable due to the lower value of their materials. However, there is potential for volume recycling due to their widespread use in everyday items.
Lead-acid battery recycling requires a lower initial investment compared to Lithium-ion and has a stable market demand.
Lithium-ion recycling involves complex processes requiring specialized knowledge and training, but the market demand is rapidly growing.
2. Different Battery Recycling Methods Used in India
The recycling methods for lead-acid and lithium-ion batteries differ due to their distinct chemistries and compositions.
Lead Acid Batteries:
Pyrometallurgy method: This involves high-temperature smelting to melt the lead and separate it from other materials. It is widely used due to its established technology and high lead recovery rate.
Hydrometallurgy: (Rarely used) This uses chemical processes to dissolve the lead in an aqueous solution, followed by precipitation to recover the lead.
Lithium Ion Batteries:
Hydrometallurgy: Similar to lead-acid but adapted for Li-ion chemistry. More complex but allows for the recovery of various valuable metals like lithium, cobalt, and nickel.
Pyrometallurgy: Adapted for Li-ion batteries, but challenges exist due to potential for lithium and other valuable metals to vaporize at high temperatures.
Direct Recycling: This is an emerging field with ongoing research and development.
Recycling infrastructure for Li-ion batteries is still developing in India. Multiple methods are being explored.
3. Licenses and Permits Required
The licenses and permits required for a battery recycling business vary from state to state. You can get help from a local consultant to ensure you obtain all the necessary licenses and permits before starting your business.
Here are some of the basic documents you may require:
- Business Registration
- GST Certificate
- Trade License
- Registration with the Ministry of Environment, Forest and Climate Change (MoEF&CC)
- Permits from the Pollution Control Board
4. Investment Required for Battery Recycling Business
You can start a small-scale lead acid battery recycling business with an investment of 10 to 20 lakhs. This could involve collecting and processing used batteries on a smaller scale, with minimal equipment and manpower.
To start a medium to large scale battery recycling business you will require an investment of 1 crore to up to 50 crores.
The investment amount to start a battery recycling business varies depending on many factors such as,
- The Type of batteries: Compared to Li-ion batteries, the investment required to start a lead acid battery is less. Recycling Li-ion batteries requires more complex technology and higher investments.
- Location: To start a recycling plant you require a large space and labor. These costs can vary depending on the location.
- Method of Recycling: Advanced recycling methods like Hydrometallurgy and Direct Recycling require a big investment.

5. Machines and Equipment Used
The specific type of machines required for a battery recycling business depends upon the type of battery you recycle, the type of recycling method you adopt, and the scale of your plant.
However, here are some of the common machines used in a battery recycling plant:
For Primary processing or Pre-treatment Equipment:
- Shredder: Breaks down batteries into smaller pieces for further processing.
- Granulator: Further reduces particle size for better separation.
- Crushing and milling: For specific components like plastics or metals.
For Separation:
- Air separators: Uses air currents to separate lighter and heavier materials.
- Wet separation: Uses specific liquids to separate materials based on density and solubility.
- Magnetic separators: Separate magnetic materials like steel and iron.
For Extraction:
- Pyrometallurgy: High-temperature processing to recover materials like lead and copper.
- Hydrometallurgy: Uses chemical solutions to dissolve and extract valuable metals.
You may also require additional equipment like dust collection systems, wastewater treatment, and material handling equipment such as conveyor belts, forklifts, etc., for moving materials within the facility.
