Transcript of Middle School Training Prezi - School Cafeteria Recycling & Composting

It's time to make a change in our cafeteria
Leftover Milk and Juice

Our Mission:
Throw Out Less Trash in the Cafeteria

> Plastic containers
> Tinfoil
> Paper plates and bowls
> Left-over food
> Milk cartons
> Paper bags
> Cardboard containers
> Plastic containers
> Metal cans
> Glass bottles
1. Collect Plastic, Glass, Metal, Cardboard and Paper for Recycling
2. Collect Left-over Food for Composting

3. Reduce the number of trash bags going to the dumpster every day
Here's how we're going to do it
Is this stuff "Trash"?
Set up Sorting Bins in the cafeteria
Left-over Food
White Bucket = Liquids
Grey Barrel = Trash
No Left-over Food in Trash
Green Bucket for Food Scraps
Green Bucket
Leftover Soup
Recipe for Compost
Compost = Nature's way to recycle
If something was once alive, it will decompose
or rot. If it rots, it can be composted.
Composting keeps food waste out of land fills and

Cafeteria "Trash" isn't 100% Trash

The cafeteria
sends more
trash to
the dumpster than any other room in the school
25% of Cafeteria Trash = Left-over Food
and Left-over Food can be composted
50% of Cafeteria Trash
can be
Only 25% of Cafeteria "Trash"
is really Trash

Paper and cardboard
Numbered plastic containers
Blue Bin = Recycling
Green Bucket = Left-over
Our school is
throwing out
too much trash
in the cafeteria
every day
Food rotting in landfills
methane gas (CH4)
and methane gas contributes to
climate change
Burning wet food in
incinerators wastes energy
Bacteria, Insects
and Worms
Compost starts out looking like this
Adding compost to gardens gives plants
the nutrients they need
to grow stronger and healthier
plastic silverware
plastic bags or wrap
snack bags
metal packets
drink pouches
paper napkins/towels
Goals for the Future:
Reduce Reuse Recycle Rot
1) All students and teachers sort cafeteria trash regularly.
Volunteer Monitors at Sorting Stations to answer questions.
Reduce number of trash bags leaving the cafeteria by 80%.

2) ONLY Left-over Food in Green Bucket.

3) Actions
Replace Styrofoam products (trays, bowls, cups or plates) with a reusable or recyclable alternative.
Replace individual mustard, ketchup, mayonnaise and salad dressing packets with pump bottles.
Replace plastic water bottles with reusable water bottles.
Look for opportunities to recycle and compost - at home, in your town and at special events, like concerts and festivals.
Stack trays and
save trash bags
and ends up
like soil
Don't Trash It
Sort It!
Learn how to sort our trash
Why Compost?
Why Recycle?
Recycling a resource material
- like glass, plastic, metal, cardboard or paper -
extends the life of that resource
3 examples
New paper products
Used cans
New metal products

Used plastic bottles
Fleece clothing, yard furniture and new plastic products
Check signs to remember
What goes where?
Saving the environment
One cafeteria at a time
When we recycle, we turn used materials into new products.
We don't waste our resources.
We use less energy.
We make less trash.
When we recycle, we save things made of
plastic, metal, paper, cardboard and glass
from a landfill or an incinerator
Blue Bin
Greens = High Nitrogen
Examples: Leftover food, grass
clippings, coffee grounds,
hay and seaweed
Browns =
High Carbon
Examples: Dead leaves,
cardboard, newspaper
and sawdust
