Yale University Food Waste Collection
Pilot Project
Training for Building Occupants & Custodial Staff
February 2014
Yale Sustainability Strategic Plan 2013-2016 Goal: Achieve a 50% waste diversion rate by June 2016 via reuse, recycling, and/or composting strategies. Currently: • 40% is diverted. • 16% is composted.
Why? The Big Picture
Why? The Big Picture

What? The Pilot Project Concept
• We hope to identify: – Best containers – Effective training for building users – Effective training for custodial staff – Challenges? – An improved approach?
• We’ll need your help & feedback!

Small: 1.5 gallons Large: 23 gallons
Labels for dining prep kitchens w/ large bins: Labels for office kitchens with small bins:
Presenter
Presentation Notes
Labels on containers will specify the types of acceptable food waste. (The difference is that for dining prep kitchens, containers will be larger and able to fit compostable materials such as plates, etc. Special reminders have also been included regarding plastic wrap and gloves which are likely to be used in kitchen prep areas.) We will also have a webpage with detailed information on the pilot project and acceptable items. Reference: acceptable food waste from compost facility in New Milford, CT: http://www.garick.com/Locations/NewMilfordFarms.aspx
Where will custodial staff take food waste? • Custodial staff: Take bags to designated brown
toter in outdoor waste collection site. • Food waste will be picked up on a regular
schedule.
Outdoor 64 gallon toters for food waste and compostable waste
Where does it go next?
• Yale Facilities takes it to a compost facility in New Milford, CT.
What happens at the compost facility?
• At the facility, food waste turns into compost through traditional windrow composting.

FAQ: What’s my role?
• Building occupants are important for ensuring that waste is properly separated in containers for food waste, recycling, and trash.
• Custodial staff are critical to ensuring correct bags are used and the food waste is taken to the correct toter.
• We want to hear feedback from you!
FAQ: Will the bin smell?
• The bins allow air flow which prevents build up of liquids, so food waste remains drier, breaking down with less mess and odor.
• Food waste will be composted off-site, not in the
building.
FAQ: Who do I contact with questions or suggestions?
We would welcome your feedback and ideas for improvement!
