In this special Festival of Circular Economy episode, guest host Mark Shayler sits down with Siddharth Hande of Kabadiwalla Connect to explore one of the most overlooked forces in global sustainability—the informal waste supply chain. From the streets of Chennai to a data-driven map reshaping how waste is collected and processed, Siddharth shares how formalising waste picking isn’t just about better recycling—it’s about transforming livelihoods, empowering communities, and unlocking hidden value in the materials we throw away. Eye-opening, inspiring, and grounded in real-world impact, this conversation will change how you see waste forever.
