Helga Kristín Jóhannsdóttir, Head of ON Power’s Geothermal Park, recently appeared as a guest on the Core Knowledge podcast, where she spoke with host Nick Sestari about how the Geothermal Park at Hellisheiði is creating a unique real-world example of a functioning circular economy.
In the episode, they discuss how companies within the Geothermal Park make use of geothermal resources and by-products in an efficient and sustainable way, reducing waste and building a collaborative ecosystem where energy and resources are fully utilized. Nick points out that the initiative at Hellisheiði is one of the most exciting projects in the world today when it comes to circular economy thinking and sustainable development within the energy sector.
Helga Kristín also explains how this approach — where geothermal energy, innovation, and collaboration between companies meet — can serve as a model for other countries and industrial areas aiming to develop more sustainable solutions and build ecosystems that use resources in a responsible and forward-thinking manner.
