Effective waste management relies on active public participation, yet engaging citizens in sustainable waste management remains a challenge. This study introduces a novel approach by developing a mobile application to support public involvement in waste management processes. Drawing upon the Persuasive Systems Design (PSD) framework, the application incorporates persuasive strategies to motivate users to adopt responsible waste handling behaviors. The developed mobile application features a set of functionalities aimed at facilitating user engagement and behavior change. These include a leaderboard to foster competition and motivation among users, a chat room for community interaction, a sorting guide for proper waste categorization, and a module for locating nearby waste collectors, thereby promoting accessibility. To assess the effectiveness and user satisfaction of the application, a structured walkthrough evaluation method was employed, complemented by questionnaire items based on the Attention, Relevance, Confidence, and Satisfaction (ARCS) model. Through this evaluation process, the study measured users’ attention to the application’s features, the relevance of its content to their needs, their confidence in using the application, and their overall satisfaction with the experience. The findings of the evaluation demonstrate the potential of the mobile application in effectively engaging users and promoting positive changes in waste management behaviors.
