The proposed vending machine aims to encourage proper plastic bottle disposal by offering seed packets as a reward. Users deposit a plastic bottle into the machine and can then choose from a selection of visible flower or vegetable seeds displayed behind a transparent glass door. After selecting a category, the machine dispenses the corresponding seed packet into the collection box. This approach not only promotes environmental awareness and recycling but also supports local agricultural activities by providing seeds for planting.

The main objective of this study is to design and implement an efficient, project-based system for collecting plastic bottles through an automated vending machine that exchanges them for seeds. This initiative seeks to benefit farmers, gardeners, and community residents by fostering a sustainable cycle of recycling and planting, turning waste into resources that support both environmental conservation and agricultural growth.
