Circularity.fm is the podcast about understanding, building and managing circular business models.
Most episode showcase one specific organisation that runs a circular business model or a business model in the circular economy. This can be a startup, an established SME or a business field of a corporate. Hence, interviews are both about founding and funding a circular business as well as transforming an existing linear business to a circular one, be it in Europe, North America, South America, Asia, Africa or Australia. The podcast focuses on experiences made in this build-up and transformation phase.

Deposit Systems: Incentivizing Take-Back at Knorr-Bremse
Remanufacturing depends on getting used products back. Can a deposit system give customers an incentive to return them?

What you'll hear in this episode:
• Why the deposit value is linked to the market value of the core, and how returning an equivalent product keeps parts flowing back
• What happens to returned cores, from assessing and disassembling them to deciding which components can be reused, reconditioned or replaced
• Which data and systems are needed to manage remanufacturing, including core return rates, regeneration rates and ERP processes for products coming back
