ITB Students Propose Utilizing Nickel Tailings to Produce Cost-Efficient LFP Battery Cathodes
Jumat, 20 - Maret - 2026

A team of three students from the Bandung Institute of Technology (ITB) has developed an innovative idea to utilize nickel tailings for the production of Lithium Iron Phosphate (LFP) battery cathodes, aiming to create a more cost-efficient and sustainable solution.
The idea was presented in a mining competition organized by the Mining Engineering Student Association (HMT-ITB). The team—Kornelius Candra Hutabarat, Adyatma Putra Fausta Hariyadi Said, and Nikolo Albertgati Barasa—submitted a project titled:
“Low-Cost LFP Battery Cathode Production from HPAL Nickel Tailings: A Techno-Economic Feasibility Study and Circular Business Model at IMIP Morowali.”
Turning Waste into Valuable Battery Materials
The team highlighted the issue of high volumes of tailings generated from the High Pressure Acid Leaching (HPAL) process, commonly used to process low-grade nickel ores in Indonesia.- Producing 1 ton of nickel can generate up to 100 tons of tailings
- These tailings are largely underutilized
“We see a huge opportunity in this underutilized waste. The iron content can be processed into an important component for LFP batteries, whose demand continues to grow,” said Kornelius.
Aligning with Global Energy Transition
The project is closely linked to global trends, particularly:- Energy transition
- Net-zero emission targets
- Rapid growth in electric vehicle (EV) demand
- More stable
- Safer
- More cost-efficient
Integrated Industrial Ecosystem Approach
The team analyzed not only the technical aspects but also:- Economic feasibility
- Business model design
- Easier access to raw materials (iron, lithium)
- Reduced logistics costs
- Higher potential profit margins
“We approached this from upstream to downstream—focusing not only on production, but also on how the business model could realistically operate,” the team explained.
Circular Economy Model
The team proposed a circular business model, inspired by Indonesia’s Domestic Market Obligation (DMO) policy in coal:- LFP cathodes are prioritized for domestic use (supporting local content / TKDN)
- Excess production can be exported
Environmental Innovation
From an environmental perspective, the innovation promotes sustainability by:- Utilizing waste as raw material
- Reducing environmental impact of tailings
- Enhanced Volatilization and Recovery (EVR) technology to recycle phosphoric acid
- Lower-temperature processing to improve energy efficiency
Challenges and Future Development
Despite its potential, the innovation is still at an early stage:- Current technology is laboratory-scale
- Requires industrial-scale development
- Scaling up the technology
- Managing lithium price volatility
Economic Potential
Based on initial simulations:- Production capacity: ~60,000 tons per year
- Estimated payback period: ~3.2 years
Conclusion
This project demonstrates a comprehensive approach combining:- Technical innovation
- Economic feasibility
- Policy alignment
The initiative not only offers a solution for mining waste management, but also opens opportunities to strengthen Indonesia’s domestic battery supply chain using local resources—supporting a more sustainable industrial future.“A good idea is one that is not only innovative, but also relevant and applicable in the real world,” the team stated.
