Partial excerpt from “Reactions of Visiting Students”
- Whenever I threw plastic bottles in the trash, I was curious about who was recycling them and how. Seeing Polaris staff washing bottles speedily and with incredible concentration, while working together as if they were using a conveyor belt, made me want to do whatever I can to lighten their load, even if it is only a small task such as separating the labels and lids.
- The clear division of roles and efficient workflow left a strong impression. Despite the challenging working conditions—particularly the temperature and humidity—I felt deep respect for everyone’s focused and diligent work ethic.I realized that many people of whom students may not be aware provide support from behind the scenes, and I would like to remember that.
