Paper presented: McKie, E.C., Sharma, N., Cho, Sanghoon and Chandrasekaran, A.. Optimizing Curbside Recycling Behaviors through AI Generated Feedback, In Revision.
Problem definition: Recycling is a critical waste management process that provides substantial benefits to the environment, society, and global economies. However, its efficacy is frequently limited by quality issues stemming from individual consumer behaviors. Addressing these behaviors presents a daunting task, due to the scarcity of educational tools that can offer both targeted and nonpunitive feedback, while also being scalable. Methodology/results: To address these challenges, we explore the use of AI-enabled curbside feedback—a novel approach that delivers personalized, nonpunitive nudges to households. Through a 6-month field experiment in a Midwest community, we deployed AI technology to administer two types of green nudges (“moral suasion” and “pure”), sending over 20,000 nudges to 1,800 households. Pure nudges focused solely on educating consumers on proper recycling processes, while moral suasion nudges appealed to the emotional aspects of recycling. We evaluated residents’ subsequent recycling quality (measured by contamination levels) and participation performance (measured by set out rates) through audits conducted with smart-recycling trucks. Compared to the no-nudge control group, we find that overall, AI-enabled nudges led to an immediate reduction in recycling contamination of 63%. Moreover, both forms of nudges improved other critical aspects of performance including recycling program participation. While both pure and moral suasion nudges reduced contamination, the moral suasion approach yielded a significantly larger immediate reduction (by 22%) and a greater overall impact (by 10%) when compared to the purely informational nudges. Managerial implications: Our results yield several insights for recycling stakeholders and policymakers. Firstly, non-punitive and scalable mechanisms, such as AI-enabled nudges, can effectively improve consumers’ recycling behaviors (without compromising their future participation in recycling programs). This underscores the importance of investing in such solutions, which have historically been unavailable. Secondly, our study illustrates the importance of emotional connections facilitated by moral nudges, which proved more effective than the mechanical connections established by pure nudges. Lastly, we find that sustaining behavioral improvements requires ongoing commitment. Managers may consider periodic refreshers to maintain the positive effects of these educational interventions.
