A series of single-day or weekend events; the Zero Waste Expo will be an educational experience with attendees having the opportunity to learn how to improve their own waste footprint. This event is aimed at anyone who is concerned about our environment and is uncertain how to get started. We also want to engage people who are already on the journey and want to learn about whatever is happening in their community now. We need to teach the public that they don’t need to be eco-warriors in the first instance - that every step you take is a step towards improving our environment.
