Abstract  This paper analyzes the teaching content, current status, underlying concepts, and the knowledge structure and thinking methods encompassed by the interdisciplinary practice activity of “waste classification and recycling”. It also puts forth teaching ideologies and innovative approaches. A 4-hour learning activity is designed for review classes, guiding students to understand waste from a chemical perspective, classify waste, and select metal waste and kitchen waste closely related to students’ lives for discussions on recycling. A chemical engineering production process model for waste resource utilization is constructed from the perspective of material transformation. Through this learning process, students deepen their understanding of the disciplinary value, develop a sense of responsibility, and enhance their ability to apply chemical engineering production process models to solve real-world problems. Reflection on the teaching effectiveness is also conducted.
