Rio Tinto and Alcoa Validate PyroGenesis Plasma Torches in Aluminum Furnace Trials
Event summary
- Rio Tinto and Alcoa presented data at the TMS 2026 conference confirming PyroGenesis' plasma torches reduce energy consumption by 35% and cycle time by 20-27% compared to natural gas burners.
- The trial, conducted in 2025, also showed a 40-50% reduction in hydrogen content and a 24-55% reduction in dross generation without compromising metal quality.
- PyroGenesis' plasma torches enabled increased throughput and potential CAPEX savings for aluminum plants facing operational capacity bottlenecks.
- The results were published in the peer-reviewed Light Metals 2026 publication and presented at the TMS annual conference.
The big picture
PyroGenesis' successful validation with industry giants Rio Tinto and Alcoa positions its plasma torches as a key technology in the aluminum sector's decarbonization efforts. With global aluminum demand projected to rise significantly by 2030 and 2050, the shift from fossil fuel-based heating to cleaner alternatives like plasma aligns with energy transition mandates. The operational efficiencies demonstrated could drive broader adoption across heavy industry as companies seek to meet net-zero targets.
