About Sublime Systems

Sublime Systems develops next‑gen cement technology and Sublime Cement®, a cleaner, more durable, and whiter replacement for ordinary Portland cement. Their ambient electrochemical manufacturing process foregoes the kiln, reducing energy intensity and emissions while co-producing pure mineral streams. The company focuses on low‑carbon cement and scalable, domestic production in the United States, with operations anchored in Somerville, Massachusetts. They collaborate with major construction and material partners to deploy cement in real-world projects and advance clean construction.
