In the NERD OUT section of the podcast, Sabira and Garr discuss the concept of industrial ecology and its connection to the circular economy. They explore the principles of industrial ecology and industrial symbiosis, which involve bridging biology with industry. They also highlight the importance of systems thinking and visualizing the interconnectedness of different industries and their impact on the circular economy. The conversation touches on the need for modeling and visually illustrating these concepts to make them more tangible. While countries like Italy, Sweden, Australia, and the Netherlands have seen success, the USA has struggled due to lack of trust between corporations and limited governmental support. The conversation also touched on the importance of non-profit and government-run programs.

In the discussion with Amanda Jordan, the group discusses the city's progress in implementing circular economy initiatives. Amanda highlights the unique factors that contribute to Phoenix's success, such as the city's ownership of waste facilities and the collaboration between different departments. Amanda also shares exciting projects, including the circular plastics micro factory and the Resource Innovation Campus. She emphasizes the importance of constituent support and education in driving circular economy solutions. Amanda envisions Phoenix becoming the most sustainable desert city and a leader in circular economy practices.
