Geo40 operates a world-first mineral recovery process.

We are supporting our motivated market partners with a low-carbon alternative to traditional colloidal silica manufactured with high energy demand.

Unlike the conventional methods of manufacturing colloidal silica, which involve the high-temperature melting of quartz-rich sand within a carbon-intensive blast furnace, our process offers a more environmentally friendly approach.

At Geo40, we recover silica directly from geothermal brine downstream of a geothermal power station before brine reinjection. The critical minerals we are recovering displace the need for disruptive surface mining and carbon-intensive industrial processes. Once cleaned of mineral content, the brine is re-injected back into the hydrothermal aquifer, contributing to the maintenance of its water balance.

This ground-breaking approach presents an opportunity to access high-quality geothermal silicas that are both low carbon and offer certain market performance benefits. Our sustainable colloidal silicas not only meet the technical requirements of various demanding applications across a myriad of industries, but also offer flexibility, allowing us to tailor our products to the specific needs of our customers.
