Critical fluorine from chip fabs, recycled in a closed loop
Moissan9 is building small chemical plants that sit beside semiconductor fabs and turn their fluoride waste back into usable fluorinated chemicals and feedstock for hydrofluoric acid made in the United States.
Chip manufacturing is dependent on fluorine. Most of it ends up in landfill after one use.
Every advanced chip is etched and cleaned with hydrofluoric acid. That fluorine starts as fluorspar, a mineral the United States imports almost entirely, much of it from a small group of countries.
After use, fabs neutralize their fluoride waste into a sludge and pay to landfill it. The fluorine in that sludge can be used to make the next batch chips instead.
What we're building
-
Plants inside the fence
Each plant is sized for one fab cluster and built next to the wastewater system that already makes the sludge, so logistics is trivial.
-
Simple chemistry
Our process turns fluoride waste into clean, high-grade fluoride products. The recovery plant never handles hydrofluoric acid.
-
Securing the semiconductor supply chain
We sell fluorine chemicals straight back to the fab, and recovered fluoride feeds domestic acid production. Either way, a fab's fluorine comes back to it instead of being replaced with imported ore.
Talk to us
We're at the bench stage and working toward a pilot with a host fab. We'd like to hear from fab facilities and sustainability teams, fluorochemical producers, and people who want to build this with us.
