This TED Talks Daily podcast features an interview with Ryan Gilliam, a cement entrepreneur, on his company's innovative approach to creating zero-carbon building materials. Gilliam explains how his company, Fortera, works *with* the existing cement industry, leveraging existing infrastructure and processes to capture CO2 emissions and create a competitive, eco-friendly cement alternative. He highlights the significant environmental impact of cement production (8% of global CO2 emissions) and details his company's method of transforming CO2 waste into a usable product, reducing emissions by up to 70%. This approach offers a model for other industries seeking to reduce their carbon footprint without sacrificing economic viability. The interview concludes with Gilliam emphasizing the importance of collaboration with existing industries to achieve large-scale emission reductions.
