Low-carbon cement, so we can keep building.
Sublime Systems is commercializing a breakthrough process to make low-carbon cement that performs like the cement you’re used to, without the environmental cost.
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.
A drop-in replacement for ready-mix
Our product replaces today’s cement with no compromises. We’re working with infrastructure owners, engineers, architects, contractors, and ready-mix concrete plants to make sure our cement performs.
Available by the metric tonne in 2023
Our electrochemical process today delivers a deep reduction in CO₂ emissions, with a clear path to zero emissions in the future.
Cement built the modern world
Sublime will keep us building for the next millennium.
