Circular economy - where goods are reused, recycled, and repurposed - could be seen as the holy grail of waste reduction. But the economics of packaging mean there's less and less incentive for modern materials to be recycled.

Entrepreneur Tom Szaky founded TerraCycle in the US more than two decades ago. And since then, he’s worked with more than 650 major brands across 21 countries to deliver solutions on recycling and reusing materials.

Tom talks to Sean Aylmer about recycling, the circular economy, and how Australia stacks up in the global push to become waste-free.
