People dispose of waste at a green waste station at an event on WashU campus.

Washington University in St. Louis is working to make all events zero waste events. The “green waste station” approach allows us to compost and recycle up to 95% of material, significantly reducing landfill waste and greenhouse gas emissions. Without these stations, we would likely capture less than 25% of the event waste.

Zero Waste is just the beginning. Take your event to the next level through a Green Event Certification. A simple checklist helps walk you through the planning process, applying a “green lens” to every step along the way.

Request Compostable Serviceware

Student groups hosting events are able to request compostable serviceware through the Student Sustainability Board. While this option is not open to the campus community at large, event organizers are encouraged to request compostable serviceware by requesting it with their order.

Rent-A-Tote

For indoor events with less than 100 people, you can rent a single 65-gallon compost tote, which will be collected at the end of the event and composted. This option is ideal for events with 100% compostable products and the ability to manage their waste stream.
