25% is Left-over Food
and food waste can be composted
Blue Bin = Recycling
50% can be Recycled
Only 25% of Cafeteria "Trash" is really Trash
1. Set up Sorting Bins in Cafeteria
The Challenge:

How to Reduce Our Trash

1. Collect items for recycling

2. Collect left-over food for composting

3. Reduce the number of trash bags
going to the dumpster

Recipe for Compost
Bacteria, Insects and Worms
Greens = High Nitrogen
Browns =
High Carbon
Composting = Nature's way to recycle
If a material was once alive, it will decompose
or rot. If it rots, it can be composted.
Composting keeps food waste out of landfills and

Plastic silverware
Plastic bags
Snack bags
Plastic wrap
Foil packets
Napkins or paper towels

Green Bucket = ONLY Food!
Goals for the Future:
Reduce Reuse Recycle Rot
1) All students and teachers sorting trash regularly.
Volunteer Monitors at Sorting Stations to answer questions.
Reduce number of trash bags leaving the cafeteria by 80%.

2) ONLY Food Waste in Green Bucket.

3) Actions
Replace Styrofoam products (trays, bowls, cups or plates) with
a reusable or recyclable/compostable alternative.
Replace individual mustard, ketchup, mayonnaise and salad
dressing packets with pump bottles.
Replace plastic water bottles with reusable water bottles.
Look for recycling opportunities at home, in your town, and at special events, like concerts and festivals.
Burning wet food in incinerators wastes energy
Food rotting in landfills produces methane gas (CH4)
and methane gas contributes to climate change
Our school is
throwing out
too much trash
in the cafeteria
every day
The cafeteria creates more trash than any
room in the school

Compost starts out looking like this
and ends up
looking like soil
Adding compost to gardens gives plants the nutrients they need to grow stronger and healthier
Don't Trash It
Stack trays and
save trash bags
2. Sort trash into the correct bin
No Left-Over Food in Trash
Numbered plastic containers
Sort It!
Plastic silverware
Plastic bags
Snack bags
Plastic wrap
Foil packets
Napkins or paper towels
Plastic containers

Check signs to remember
What Goes Where?
Why Compost?
Why Recycle?
Recycling a resource material
-like glass, plastic, metal, cardboard or paper -
extends the life of that resource

Used metal cans
Used plastic bottles
New paper products
Fleece clothing, yard furniture and new plastic products
New metal products
3 examples
What's the Solution?
No Left-Over Food
in Recycling
Saving the environment
One cafeteria at a time
Recycling saves resources and energy.
When we recycle, we save things made of
plastic, metal, paper, cardboard and glass
from a landfill or an incinerator.
When we recycle, we turn used materials into new products.
We don't waste our resources.
We use less energy.
We make less trash.
Examples: Leftover food, grass
clippings, coffee grounds,
hay and seaweed
Examples: Dead leaves, cardboard, newspaper and sawdust
