to valorize and remediate mining waste streams. This collaboration underscores SiTration's pivotal role in catalyzing a green revolution within the mining sector.

"The key to our membrane technology lies in the combination of durability and the selective extraction performance that is unparalleled among existing solutions," said Professor Jeffrey Grossman, co-founder of SiTration and professor at MIT's Department of Materials Science and Engineering. "Additionally, the membrane is produced via a streamlined, scalable, and economic manufacturing process, allowing for its deployment in large-scale industrial applications."

Beyond revolutionizing clean energy material sourcing, the company is extending its membrane platform to metals refining and lithium-ion battery recycling, further solidifying its commitment to sustainability across a wide range of industries.

"The need for breakthrough technology that addresses the staggering shortage of critical metals the world is facing as we transition to a clean, electrified energy system is real," said Jacob Bro, Partner at 2150. "With SiTration, we believe we have found the most promising technology and an incredible team to take it to commercial scale in global mining and in the emerging battery recycling industry."

About SiTration
SiTration is a spin-out of MIT that has created a patented porous silicon membrane technology that provides a unique combination of ultra-durability, highly tunable pore structure, and electrical conductivity enabling efficient and low-cost materials recovery. SiTration's technology can replace traditional resource-intensive mining processes and can be deployed to recover materials from traditionally inaccessible sources, including waste. The company has received grants from the Department of Energy's ARPA-E and the National Science Foundation, and is working to implement their membrane platform in mining, metals refining, and lithium-ion battery recycling.

About 2150
