MTRAC Impact: Where Are They Now?
What happens after an MTRAC project ends? For Michigan Tech researcher Dr. Timothy Eisele, the momentum continues. Eisele recently completed his 2025 MTRAC Advanced Materials project, “Bioextraction of Nickel from Recycled Batteries,” exploring biological approaches to recovering valuable nickel from recycled battery materials.
Now, his research into sustainable metals recovery is attracting significant federal investment. Eisele recently received $1,035,309 from the U.S. Department of Energy to develop a bioleaching process that could transform low-cost, low-grade iron ore waste into valuable feedstock for ironmaking. The award follows another recent $700,000 DOE award supporting his research into biological production of high-grade manganese dioxide from low-grade sources. That's more than $1.7 million in recent DOE funding supporting innovative approaches to metals extraction and recovery.
The work is particularly timely. Nickel and other critical materials are essential to batteries, energy technologies, steelmaking, and U.S. manufacturing, yet their global supply chains remain highly concentrated. Indonesia, the world's dominant nickel producer has significantly reduced nickel ore production quotas in 2026.
Finding new ways to recover critical materials from recycled batteries, low-grade ores, mine wastes, and other secondary sources could help diversify supply while reducing waste and environmental impacts. Eisele's work is also advancing toward commercialization through Impetra Metals, his startup focused on sustainable metals recovery.
Congratulations to Dr. Eisele and his team on the continued momentum! This is what translational research looks like.
