SiTration is a materials recovery company developing patented silicon membrane technology for chemical-free, energy-efficient extraction and recycling of critical minerals like copper, cobalt, nickel, lithium, and precious metals.[1][2][4] It serves the mining, metals refining, and li-ion battery recycling industries by addressing resource-intensive traditional processes, lowering costs, reducing pollution, and enabling recovery from dilute or waste streams such as mining wastewater and spent batteries.[1][2][3] The company solves key supply chain bottlenecks for electrification and AI technologies, including batteries, electric motors, and data centers, with strong growth momentum shown by a new scaling facility opened in April 2025, an $11.8 million seed round led by 2150, and partnerships like Rio Tinto for pilot deployments.[1][2]
SiTration spun out from MIT research in 2020, founded by CEO Dr. Brendan Smith and co-founders who advanced novel silicon membrane technology originally developed at MIT for durable, tunable filtration under harsh conditions.[1][2][5] The idea emerged from MIT work on electricity-conducting silicon membranes that withstand chemicals and high temperatures, enabling efficient separations without heavy chemical use—pioneering a shift from conventional mining to "full value mining" from complex or waste sources.[1][2] Early traction included a June 2023 partnership with Rio Tinto to adapt the tech for mine wastewater, successful site tests, and plans for scaled pilots processing up to 100 cubic meters per hour, culminating in the 2025 facility ribbon-cutting by Dr. Smith with state leaders present.[1][2]
SiTration rides the surging demand for critical minerals amid global electrification, AI data centers, and clean energy transitions, where supply shortages threaten EV batteries, wind turbines, and motors.[1][2] Timing is ideal as mining faces environmental scrutiny and traditional methods prove inefficient for low-concentration ores or waste—market forces like regulatory pressures for sustainability and U.S. reshoring favor its low-impact tech.[1][2] It influences the ecosystem by enabling "full value mining," remediating waste (e.g., Rio Tinto streams), supplementing primary mining, and accelerating circular economy for batteries, potentially reducing reliance on geopolitically sensitive supplies.[1][2][4]
SiTration is poised for commercial breakthroughs with its 2025 facility enabling faster global pilots and team expansion, targeting deployments with mining leaders to prove profitability at scale.[1] Trends like mineral scarcity, stricter ESG mandates, and battery recycling mandates will propel growth, evolving its role from innovator to essential supply chain player—potentially reshaping sustainable materials recovery as electrification accelerates.[2] This positions SiTration to deliver on its promise of efficient, world-class extraction, directly fueling the tech powering tomorrow's EVs and AI infrastructure.[1][2]
SiTration has raised $2.0M across 1 funding round. Most recently, it raised $2.0M Seed in July 2022.
