Low-carbon cement, so
we can keep building.

Sublime Systems’ electrified manufacturing process makes low-carbon cement that performs like the building material you’re used to, without the carbon emissions

Extraordinary technology. Ordinary product.

Electrifying cement production

Sublime’s process forgoes the kiln entirely — which is the most energy and fossil fuel-intensive part of the cement manufacturing process.
