The article highlights that while consumer awareness of sustainable food packaging disposal is growing, confusion around packaging symbols and mixed-material disposal persists, hindering effective recycling. Using quick, engaging quizzes across all age groups at community events proved successful in identifying knowledge gaps and encouraging willingness to adopt better disposal practices. The study underscores the need for clearer labeling, improved recycling infrastructure, and coordinated efforts from schools, businesses, and government to support consumers in sustainable behavior changes. This work aligns with the UN SDG goals by promoting quality education (Goal 4), fostering innovation and infrastructure (Goal 9), and encouraging responsible consumption and production (Goal 12).
