The Symposium is the most informative and fun event for any Zero Waste professional or passionate community member in the North Bay.
2024 Attendee
I thought it might have been just a just a conference and the thought of sitting all day through all the speakers seemed like alot and then I was fascinated by all the speakers who were entertaining and uplifting. I did not want to take a break! I also love meeting many others in the sustainability community and thought it was coordinated in a very fun way!
