Personal Trash Choices

Group Activity for Youth or Adults


  • Four signs or labels, placed around the room: Trash, Reduce, Reuse, Recycle
  • A collection of "trash" items, such as: snack packages (like individual plastic containers for applesauce or pudding), plastic drink bottle, glass drink bottle, newspaper, plastic shopping bag, glass food jar...


Ask participants to be ready to move throughout the room. Explain that you will be showing them items that might be identified as trash. Ask participants to move to stand near the sign that describes how they would deal with this item in their life. Meaning, they would not buy this in the first place (REDUCE), they would buy it and then REUSE it somehow, they would buy it and then RECYCLE it, they would buy it and put it in the TRASH when they are done with it. Explain that there is no wrong answer, but that they should be able to argue for their choice.

Hold up one of the items and allow time for participants to gather, then ask a few people to explain why they chose to stand where they did. For example they might say, "I would reduce this newspaper because I read my news on the internet." Or, "I like to eat premade pasta sauce but I reuse the jars to store leftovers." If you want, you can give participants a chance to change if they are convinced by someone else's justification.

Think carefully about the trash items you choose to make sure they are items your participants will relate to. You could frame it as them choosing to influence their family members if that is more appropriate for their age.
