- 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...
Engage participants in the understanding that there are different levels of solutions to problems in a community.
Individuals can have a particular level of impact when they engage in individual-level solutions. These individual
solutions can be amplified when they are shared with others in the community, and can serve to encourage
community-level solutions. Community-level solutions have a different level of impact, as they inherently reach
a larger number of people. When we think about community-level solutions to waste we might think of container
deposit laws (where you pay extra for a beverage bottle, for example, and then get that money back when you
return the bottle for recycling or reuse), plastic bag bans, bans on foam food take-out containers, extended
producer responsibility laws (where the manufacturer of a product is responsible for its ultimate disposal,
recycling, or reuse). Participants may be able to describe other community-level solutions. In this activity
participants will consider individual-level solutions, which can be effective and empowering, particularly for
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 their choice
if they are swayed by someone else's argument.
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.
