A Concrete Plan for Sustainable Cement | Ryan Gilliam | TED

Cement is one of the most-consumed materials on Earth — second only to water — and it accounts for a whopping eight percent of the world's carbon pollution. What if we could turn this climate villain into a hero? Clean tech innovator and serial entrepreneur Ryan Gilliam reveals his company's surprisingly simple process for transforming waste from the cement-making process back into limestone using existing infrastructure, creating a competitive and eco-friendly product that could pave the way for gigaton-scale climate solutions. (Recorded at TED Countdown: Overcoming Dilemmas in the Green Transition on October 30, 2024) Countdown is TED's global initiative to accelerate solutions to the climate crisis. The goal: to build a better future by cutting greenhouse gas emissions in half by 2030, in the race to a zero-carbon world.
