The SUP Free School Programme by Making Oceans Plastic Free (2022) in Indonesia shows how strong monitoring can drive measurable results. By closely tracking student behavior and plastic use, schools recorded clear progress toward reducing single-use plastics.
Annual data showed impressive per-student reductions:
-
326 fewer plastic bags
-
296 fewer takeaway containers
-
275 fewer plastic straws
-
333 fewer plastic bottles
-
446 fewer items of other plastic packaging
This led to an estimated 40% drop in plastic use per student, translating into a lifetime reduction of over 14,900 kg of plastic waste per class.
Plastic Diaries Monitoring Data (Kobbe 2022a)
This dataset presents annual monitoring results from student “plastic diaries” documenting daily single-use plastic consumption. It provides detailed evidence of behavior change and the reduction of various plastic items in participating schools.
The program also boosted awareness. Student surveys revealed a 32% increase in understanding the risks of plastic pollution and a 23% improvement in knowledge of reduction strategies.
Student Knowledge Survey Data (Kobbe, 2022b)
This dataset summarizes pre- and post-program survey results measuring student knowledge about single-use plastics. It includes insights into awareness of environmental impacts and understanding of plastic reduction strategies.
