SiTration, Inc.

SiTration is a Cambridge, Massachusetts materials-recovery company spun out of MIT that uses a patented, ultra-durable porous silicon membrane paired with electro-extraction to pull critical metals - lithium, cobalt, nickel, copper, and precious metals - out of mining waste, spent lithium-ion batteries, and refining streams. By replacing chemical-heavy, acid-dissolution processes with a tunable, energy-efficient membrane, SiTration aims to make the recovery of the metals behind batteries, EV motors, wind turbines, and data centers cheaper and cleaner.
