978-0882681/283In this phase, I translated the experimental bioplastic materials into functional everyday products, focusing on verifying their usability and refining the material formulas for future machine production. The goal was not only to test how the bioplastic performs in real-life applications but also to define clear and reproducible ingredient ratios that users could later apply through the automated machine.

Building on my previous material studies, I developed three product prototypes: a vegetable-based film for food packaging, a biodegradable cup, and a tea bag membrane.

  • Vegetable Film Packaging:
    I combined fruit and vegetable residues to create a thin, semi-transparent film suitable for wrapping fresh produce. By adjusting the glycerol content, I achieved the ideal balance between flexibility and strength, allowing the film to stretch without tearing while maintaining breathability—an important quality for food preservation.
  • Biodegradable Cup:
    Using a thicker blend of peel pulp and starch, I molded small cups capable of holding liquid for short durations. Through repeated tests, I optimized the drying temperature and structural layering to enhance water resistance while keeping the cup fully compostable. The results demonstrated that waste-derived bioplastics can replace conventional disposable tableware in low-impact scenarios.
  • Tea Bag Film:
    Inspired by daily rituals, I used tea leaf waste as both a material and a symbolic element. I created a thin, porous film suitable for containing tea, which slowly dissolves or softens in hot water. This experiment explored controlled biodegradation, expanding the sensory and functional potential of biomaterials.

978-0882681/283Throughout this phase, I documented each prototype’s recipe, process parameters, and performance data, establishing a practical material database. These results provided the foundation for the next design stage—developing a household machine that allows users to reproduce and customize these bioplastic materials autonomously using their own kitchen waste.
