DoD awards $4.22M to Rare Earth Salts to increase production of terbium and other rare earth elements

The Department of Defense announced a $4.22-million award to Rare Earth Salts in Nebraska for developing and expanding production of terbium oxide from recycled fluorescent light bulbs.

Terbium is an essential element for rare earth magnets in many key defense systems. This effort is funded through the Defense Production Act Investment (DPAI) office and aligns with the National Defense Industrial Strategy’s priority of increasing supply chain resilience by expanding domestic production and sustainment of critical production.

Terbium adds temperature resiliency to neodymium iron boron (NdFeB) magnets used in multiple key defense systems including aircraft, submarines, and missiles. Making up less than 1% of the total rare earth content in most deposits, it is one of the hardest elements to source.

Rare Earth Salts is uniquely positioned as one of the only terbium oxide producers outside of China and uses environmentally conscious recycling processes. As co-products, the company will also recover the rare earths lanthanum, cerium, europium, and yttrium, each with their own applications in commercial industry and defense.

The DPAI office has issued more than 50 program awards in FY2024 across multiple areas, totaling $518.7 million. DPAI is overseen by the ASD(IBP)’s Manufacturing Capability Expansion and Investment Prioritization (MCEIP) directorate in the Office of the Deputy Assistant Secretary of Defense for Industrial Base Resilience.
