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.

Order a Green Waste Station

For $105 per station, a full waste station will be delivered, set up prior to your event, and cleared out after the event. If you prefer to set up and take down the waste station yourself, there is a $70 fee for the delivery and pick-up of each station (includes all components.) Two volunteers or 1 trained porter are required to cover each Green Waste Station. For a fee of $35/hr, a trained porter from WFF can manage the station. One large yellow tote is included for each 200 people, unless otherwise indicate in the notes section of the request form.

Sustainable Flowers

Most people don’t realize that the floral industry generates many of the same environmental and social concerns as the food industry. Concepts such as local sourcing; waste reduction through reuse, composting and recycling; avoiding pesticides and chemicals; and fair compensation and safe conditions for workers can be applied to floral purchases for events and decorations.
