Waste Diversion
Pilot Stage of Organics Collection Planning
Summer Pilot 2016: Rachel Mazac and Jenni Abere
61.92 tons trash/food waste in Anderson Center at $65/ton trash
25% diverted (composted or recycled) = $1006.20 saved
50% diverted (composted or recycled) = $2012.40 saved
Bathrooms (ABM):
- One side car or small trash bin for each bathroom
- One sign (paper towels only for composting) for each bathroom
- Large compostable bags
- Small trash liners
Starbucks (Aramark):
- Change trash “hole” in cart to compost -- bin next to cart for trash
- Sign (3D sign) to label bins clearly
- Small compostable bags
Bistro (Aramark):
- If we continue pig farm collection for pilot stage:
- Signs: Food waste only for animal feed (are there limits to pig feed that could be composted? bones?).
- Napkins for compost.
- Large compostable bags
- Another bin needed for trash/recycling
- Not many trash items produced here.
- Signs: Food waste only for animal feed (are there limits to pig feed that could be composted? bones?).
- If we replace pig farm with organics right away:
- Large bin (preferably no bag and can be directly dumped by lift or truck) for food waste and napkins
- Signs: organics (all: food and napkins), other trash
- Concern: larger bin such as a 90 would not fit inside the “boxes” for trash
Catering (Aramark):
- 2-3 smaller portable compost bins (60s or 30s) -- or many 90s so they can be directly dumped by trucks when full (less labor).
- Small or medium size compostable bags
- Signs: food waste and certified compostable materials (napkins, plates, cups, etc)
- Need to have certified compostable materials for catered events
Loading Dock (Facilities/ABM):
- Green 90s kept in loading dock or recycling room to collect compost from smaller bins.
- When full, bins can be rolled out and picked up and dumped directly by trucks until the point where we get a dumpster/lift for organics
