The Waste Not Why Not podcast seeks to educate listeners on the best ways to help the environment with a specific focus on waste and the circular economy. The podcast team fills the circularity knowledge gap by making the science behind closing the loop fun and informative. The podcast hosts tell inspiring stories and feature scientists as guest speakers. The podcast currently has a few thousand listeners from Australia, New Zealand, Taiwan, the US, Hong Kong and the EU. The solution can have a social impact by improving access to education and knowledge of sustainable consumption choices. Especially among millennials, concern about the state of the world, known as climate anxiety, has been shown to be widespread and serious, so a podcast that empowers young listeners with a message of optimism yields a positive social impact.
