Free your school from the grip of the single-use waste monster!

Help your school reduce lunchtime waste by starting a Trash Free Lunch program. Teach and encourage students to reduce waste by packing food and drinks from home in reusable containers instead of single-use plastics along with reusable utensils and cloth napkins. Reducing your lunchtime waste goes a long way in creating a more sustainable school campus.

Within this toolkit, you’ll find various downloadable resources. For your convenience, you can access them all in one place by clicking on this link to view them in a Google Drive folder.


Toolkit Details

Why It's Important

Packaging that we use one time and throw away drains Earth’s natural resources and fills up landfills contributing to the planet’s mounting plastic pollution problem.

What You Will Accomplish

Trash Free Lunches make less waste, save natural resources and cut down on pollution in the air that causes climate change. Families can also save money by buying packaged food in bulk and buying whole fruits and vegetables with no packaging.

Educator Project Plan

Follow the steps below to set up a successful Trash Free Lunch at your school! Need help? Contact us!

Track your metrics and submit your impact wrap up form after implementing this toolkit. Your feedback helps keep our programs free for all across the globe.

Determine Participants

Use the Trash Free Lunch Sign-Up Sheet Template to assemble your team!

  • A Student Group (such as a club, before/after school program, non-school organization)
  • A whole class
  • The whole school
  • Working with a small group of students? Hold a single day Trash Free Lunch event
  • Working with a larger team? Build a campaign around going Trash Free one day a week (ex. Trash Free Tuesdays)
  • Is your whole school involved? Strive to have the school be Trash Free every day

Why Litter is Rubbish!

The resources provided below can be shown as a slideshow or printed out as individual worksheets for students to learn.

Lunches Create a Lot of Waste

Whether you’re packing a full lunch for school, bringing a snack for recess or packing food to go somewhere on the weekends, choosing to pack Trash Free reduces waste, saves the environment and saves money! According to the EPA, the average American student creates 67 pounds of lunch packaging waste each school year. That’s more than 18,000 pounds (about the same weight as two elephants!) of plastic, paper, and other non-food materials for just one average-sized elementary school (EcoCycle). [1]

Most Packaging is Difficult to Recycle

In 2021, only 5-6% of plastic was recycled in the United States! That means out of 100 pieces of plastic, only 5 or 6 got recycled into new items that we can use. Previously, the US sent most plastic waste to other countries like China and Turkey to get recycled, but this is no longer an option. Also, most packaging is difficult to recycle due to the material it’s made of or it is dirty with leftover food. So even when we put plastic in the recycle bin, most of it will still end up in a landfill. This plastic packaging is made from oil, a natural resource that comes from the earth. It takes energy to make oil, and the process causes pollution contributing to the climate crisis. [2] & [3]

Choose to Go Trash-Free!

So what can you do about this? We all know the 3 Rs: Reduce, Reuse, and Recycle. Starting with the most important R, Reduce using single use items typically found in packed lunches. By making simple changes, like packing food and drinks in reusable containers and bringing reusable utensils/cloth napkins. You will reduce your waste and make your school and community more sustainable!

Why Trash is an Environmental Justice Issue

Waste is often classified as an environmental justice issue due to the implications associated with where it is transported. Recycling facilities, waste transfer stations, incinerators, and landfills are all largely placed in developing regions internationally or in disenfranchised communities within the US. Any one or a combination of these facilities can cause widespread pollution in addition to health issues to the communities that live nearby.

Think About It!

Pre-Activity Questions

  • What are the most common types of packaging you see in your lunch and other kids’ lunches at your school?
  • What are some changes you can make in your own lunch to use less packaging and make less trash?

Take Action: How to LAUNCH Trash Free Lunch

Lead students in the “Trash Free Lunch” activity with guided instructions. Check out “Pro Tips” for more useful help:

1. Assign Roles

  • Determine who and how many students/staff are participating. Use the Trash Free Lunch Sign Up Sheet.
  • Assign students to educate peers, share the program throughout the school community and/or keep track of the results.

2. Plan It Out

Decide on a  date that you want to start your Trash Free Lunch campaign. Use the Trash Free Lunch Organizer. and decide if you want to encourage students to go Trash Free one time, one day each week, or every day.

3. Your School’s Lunches Before LAUNCHing

  • Schedule a day before your Trash Free Lunch campaign to count school lunches and how many are completely trash free or have some trash free items such as a reusable lunch box or water bottle. This is your “Audit.”
  • Print out the Trash Free Lunch Audit worksheet and head out to the lunch area with your team. Using tally marks, count the number of students at lunchtime who have brought a packed lunch to school. Out of those students, count how many students have completely Trash Free lunches, mostly Trash Free lunches and partially Trash Free lunches. A Trash Free Lunch is one in which all items can be eaten (or reused (i.e. Lunch box, water bottle, snack and food containers, utensil, napkin) and there are no single-use items or packaging. Fruit and veggie scraps such as a banana peel or apple core should be counted as Trash Free!
  • Record the data on the audit form and keep it somewhere you can access later to compare it to future audits that take place after your campaign.

If there are too many lunches to count, consider taking a large sample (about 100 students) and use what you’ve found to estimate the amounts for your whole school.

4. Educate Your Classmates and School Staff

  • Teach your peers how and why to pack a Trash Free Lunch. Present the results of your audit and the Trash Free Lunch Script at a school assembly, over announcements or by going class to class.
  • Spread the word about the program on campus by making posters and posting these flyers (How To Pack a Trash Free Lunch and Pack This Not That flyers) around school, on your school’s website or in an online school newsletter.
  • It’s important to never look down on a student about bringing waste to school. Even one item in a reusable container should be celebrated! Reward all improvements with praise.
  • Celebrate all positive changes! Even one item in a reusable container should be celebrated! Reward all improvements with praise.

5. Educate Parents

Teach the parents at your school how and why to pack Trash Free for their students by sending home this flier in a school newsletter or posting it on the school’s website.

6. Count Your Success!

Using your Trash Free Lunch Audit worksheet, pick a date to audit your school’s lunches again.

  • If you are choosing a “single day” goal for your campus to be Trash Free, conduct your post audit on that day.
  • If you are choosing “one day a week” goal to be Trash Free, wait at least one week after your Campaign and conduct your audit on that day of the week.
  • If you are choosing to go Trash Free every day, you can audit the school lunches weekly or monthly to see how it’s going

Purchase a fun stamp and non-toxic ink pad to stamp student’s hands who are packing Trash Free items.

7. Report Your Success

Be sure to let the whole school know how they did and the progress they are making to reduce their waste by making announcements about the increase in Trash Free Lunches and reusable items.

Make it a contest and see which grade or class can bring the most Trash Free Lunches on a given day. Reward the winners with a party, shout-outs during school announcements, or extended recesses.
