Amermin, Ulterra take critical minerals recycling partnership global 

US critical minerals recycler and refiner Amermin and Ulterra Drilling Technologies announced Monday an international expansion of their partnership to recycle critical minerals. 

Amermin will now process Ulterra’s waste streams from Argentina and Canada in addition to materials from their US-based operations.  

Together, the Texas-based companies recycle more than 21 waste streams, including tungsten, cobalt, copper, nickel, zinc, silver, carbon, iron, manganese, blast media, and synthetic and industrial diamond. 

In January, Amermin was awarded an $11.5 million grant from the U.S. Department of Energy’s (DOE’s) Office of Fossil Energy and Carbon Management to scale up its processing capabilities.  

By recovering and reprocessing end-of-life materials into manufacturing-grade inputs, the companies’ say they aim to build up domestic supply of critical minerals—reducing reliance on high-risk supply chains while extending the resource lifecycle. 

“Reducing dependence on geopolitically complex supply chains for critical minerals is a strategic priority for the United States,” Amermin CEO Ryan McAdams said in a news release.  

“Building resilient, allied supply networks, alongside scaling domestic and international recycling, will be key to meeting the growing demand for advanced technologies,” McAdams said. “Our expanded partnership with Ulterra supports the recovery of critical minerals from trusted partners, strengthening both supply security and sustainability.” 

In 2025, Amermin recycled more than 1.4 million pounds of material from Ulterra, it said.
