Our Process
How We Recycle
At PUNAR Energy, we are dedicated to ensuring a sustainable future through responsible recycling of lithium-ion batteries. Our innovative recycling process is designed to recover valuable materials, reduce environmental impact, and achieve net-zero waste. Here’s how we do it:
Step 1: Battery Collection
We begin by collecting used lithium-ion batteries from various sources, including industries, businesses, and consumers. Our collection network ensures that batteries are gathered safely and efficiently, minimizing the risk of leakage or damage.
Step 2: Segregation
Once collected, the batteries are carefully sorted based on their type, size, and chemical composition. This segregation step is crucial for optimizing the subsequent recycling process, allowing us to tailor the treatment methods to the specific materials contained within each battery type.
Step 3: Mechanical Process (Recover black mass and secondary products)
In this stage, the batteries undergo a mechanical process where they are safely dismantled, and the materials are separated. The key goal is to recover the Black Mass — a concentrated mix of critical metals like lithium, cobalt, nickel, and manganese. Additionally, secondary products like plastic, aluminum, steel, and copper are also extracted for further use.
Step 4: Chemical Process to recover rare earth materials and net zero waste.
To recover rare earth materials, we use a specialized chemical process that extracts and purifies elements such as lithium, cobalt, nickel, and manganese from the Black Mass. This process is designed to minimize waste and maximize recovery efficiency, ensuring that every element is reused, and nothing goes to waste. Our chemical processing achieves net-zero waste, contributing to a circular economy and promoting sustainability.
