What does a closed-loop organic waste system actually look like on a university campus? Join us live from the University of Sydney’s biodigester, where Behaviour Change Senior Officer Ysobel Cranfield, Biodigester Operator and Gardner Ben Loughnan and Sustainability Engagement Specialist Madeleine Culp walk you through the full loop – how organic waste is collected across campus, how the machine works, and how the output goes back into our gardens. We cover the management side, the practical challenges, and how we build education and engagement around an industrial composter in the middle of a working campus. Whether you’re exploring what’s possible or looking to compare notes on your own system, bring your questions.
