Signature Work Project Overview

This research aims to test the effectiveness of the application of nudge theory and fun theory in changing recycling behavior. More specifically, this study examines how the recycling nudge stickers that are attached to product packaging and trash bins can influence individual waste sorting behaviors in China. This study uses both qualitative method such as focus group and interviews as well as quantitative method of experiment to collect and analyze data. By attaching the stickers designed based on the trash bin color, sign, and category to the product packaging and trash cans, this study tries to help the participants match the waste with its corresponding trash can with the same stickers. It is hypothesized that the experiment participants’ recycling awareness will be elevated, and the recycling accuracy will be improved by reducing the information gap between participant’s perception and the existing categories that are established by the government. This research finds that the nudge stickers are statistically significant to change individual waste-sorting behavior, but the fun theory application can be confusing to the participants due to short-period exposure. The study also discovers that male and female participants have enhanced accuracy in the experimental groups, while the non-Chinese participants have higher accuracy change rate than the Chinese participants. By interviewing the participants after the experiment, the study suggests that the size, placement, and color of the stickers should be refined based on the color contrast theory and the experimental design can be revised to raise participants’ attention level for better performances.
