Engineering, Solids Co-op

Sublime is advancing a breakthrough, clean, efficient, low-waste process for manufacturing cement, the essential ingredient in the most-consumed human-made material on Earth: concrete. Replacing 200-year-old manufacturing methods that are reliant on kilns running hotter than lava, our near-ambient-temperature, electrochemical technology manufactures industry-accepted cement and critical minerals. We're partnering with leading general contractors, concrete producers, developers, and technology hyperscalers to deploy our clean, durable, beautiful Sublime Cement?? in infrastructure that is defining the future of clean construction. Backed by some of the world's largest cement producers, leading private investors, and the U.S. Department of Energy, we are assembling a talented, collaborative team that is "amped about cement" (pun intended) and committed to operating on the frontiers of material science, manufacturing, industry, construction, and commercial partnerships, to advance cement innovation that will endure for the next millennium.
