At ICBR 2025, global experts and industry leaders gathered to address the challenges and opportunities shaping the future of battery recycling. As lithium-ion batteries continue to power electric mobility and renewable energy storage, recycling has become a critical enabler of the circular economy, ensuring resource recovery, safety, and sustainability across the value chain.
For us, the conference was not only a chance to connect with partners, but also to reflect on the key industry trends and how our filtration systems are helping meet these evolving needs.
Key Trends in Battery Recycling – and How We Align
1. Black Mass Recovery at Industrial Scale
One of the most discussed topics at ICBR was the growing demand for efficient black mass recovery, the crucial step in extracting valuable metals such as nickel, cobalt, and lithium.
Our alignment: Dongou’s microporous filtration systems provide precise solid-liquid separation in lithium-ion battery recycling, ensuring stable particle morphology, high throughput, and reliable recovery of active materials. This allows recyclers to scale up operations while minimizing material loss.
Our alignment: Dongou’s microporous filtration systems ensure precise solid-liquid separation for efficient black mass recovery. A key advantage is their ability to recapture valuable metals that escape from the primary process stream, allowing recyclers to re-introduce these metals into the recovery system. This on-process recycling boosts overall metal extraction rates, minimizes material loss, and supports scalable, high-throughput operations.
2. Sustainability and Process Efficiency
Sustainability was a recurring theme at ICBR. The industry is moving toward greener processes that reduce waste, optimize energy use, and extend the lifecycle of equipment.
Our alignment: Our sustainable filtration elements are durable and regenerable, engineered to extend service life and lower total operating costs. The short-process integration of our system further reduces the footprint and equipment investment, helping recyclers achieve both environmental and economic objectives with less waste and optimized resource use.
Our Technology Focus
Building on these industry priorities, we continue to advance filtration technologies that:
·Deliver micron-level precision separation to stabilize recycling processes.
·Integrate filtration, washing, and concentration into compact process steps for higher efficiency.
·Ensure reliable system performance under demanding battery material applications.
These innovations reflect more than a decade of experience in battery materials and recycling, making filtration not just a support function, but a driver of process quality and sustainability.
Looking Ahead
ICBR 2025 once again highlighted how essential battery recycling is to building a sustainable energy ecosystem. From black mass recovery to safe waste handling and sustainable process design, the industry is clearly moving toward greater efficiency, compliance, and circularity.
At Dongou, we continue to focus on technologies that improve process control, reduce environmental impact, and ensure reliable long-term performance. Together with industry partners, we aim to refine solutions that support the safe and sustainable growth of the battery value chain.
