PET Recycling Machine Student Workbook

This workbook is structured as a guided learning journey that introduces students to the practical process of recycling PET bottles into 3D printing filament. Through clearly defined phases, students explore how a PET filament recycler works, identify its main components, learn which materials and tools are needed, and understand how plastic bottles must be prepared before recycling.

The activities focus on observation, classification, and hands-on experimentation, combining creative tasks such as designing and building filament spools with technical work in Tinkercad and basic 3D printing concepts. Students also investigate real recycling methods, use artificial intelligence to generate 3D object ideas, and reflect on how recycled filament can be used to solve everyday needs in the classroom or school environment.

Throughout the workbook, learning is documented step by step using visual templates, diagrams, and guided prompts that support collaboration, reasoning, and communication. The final presentation phase encourages students to explain their process through audiovisual storytelling, making the connection between recycling, design, and sustainability visible and meaningful.
