About
Sublime Systems is a climate tech company developing a next-generation cement manufacturing process that replaces traditional high-emission kilns with an electrochemical process. Their product, Sublime Cement®, reduces energy use by 30–40%, eliminates CO2 and other pollutants, and co-produces critical minerals from low-value feedstocks. The company has been deploying cement in real-world projects since 2023 and is scaling toward kiloton-scale production.
Problem
Conventional portland cement production is highly energy-intensive and emits large amounts of CO2, NOx, SOx, and other pollutants, contributing significantly to climate change.
For
construction companies, architects, cement manufacturers, and technology hyperscalers seeking low-carbon building materials
How it works
Sublime replaces the traditional kiln with a targeted electrochemical process that operates at ambient temperature, converting rocks and industrial waste into clean cement while co-producing pure critical mineral streams.
