Why We Made this Film
Humanity produces a staggering four billion tons of cement annually - the foundation upon which the modern world is built. Unfortunately, its environmental toll is equally as astonishing. At a whopping 8% of global emissions, the cement industry is one of the biggest global GHG emitters - not to mention the most abundant man-made material on the planet. Decarbonizing this sector is crucial if we are ever going to make meaningful progress on climate change.
That’s why we wanted to speak with Leah Ellis of Sublime Systems. Along with her Co-Founder Yet-Ming Chiang, they’re fully electrifying cement production by leveraging cheap renewables and chemical storage to make carbon-free lime. By applying proven industrial electrochemical concepts, Sublime is creating a platform to sustainably scale the world’s demand for this building material.
