Secondary school

“Da’s proper!” (Zero waste!) is a workshop about waste management that teaches children everything about sorting rules, recycling, prevention, reuse, litter, social economy, sustainable development and legislation. This can be done in a playful way in a quiz or in a role-playing activity, but also more seriously in a debate. The workshop always uses young people’s experiences as a starting point.

What is the activity about?

You can choose one of three formats:


During the quiz, the students individually solve twelve multiple choice questions, which they correct together. The answers are used as a starting point for a discussion about waste management. The students are coached to draw a number of conclusions from the correct answers.


In the role-play about a fictional waste problem, students play the role of a major stakeholder: a collection service, sorting centre, packaging producer, mayor, etc. They inform each other, come up with solutions and draw conclusions.


The debate starts with an introductory clip that presents a number of hypotheses to the students, who have been divided into small groups. The groups formulate the pros and cons together. The entire class then discusses these hypotheses and the students draw conclusions together.
