This study explores public perceptions of Batu City, Indonesia the waste economy and waste management as an economic resource. The research aims to map societal views on waste as an economic resource, highlighting opportunities for behavioral change and sustainable practices. The novelty of this study lies in integrating digital public discourse with waste economy concepts, offering a socio-digital perspective that extends beyond purely technical or policy-oriented approaches. The findings emphasize the need for improved public education on reduction and reuse and for strengthening waste management infrastructure, providing practical insights for policy development, community empowerment, and the advancement of sustainable green economy strategies. Data were collected through web scraping from Twitter platform throughout 2023, within a one-year research period, yielding 3,964 reviews. After preprocessing (case folding, tokenizing, spelling normalization, and stopword removal), 630 cleaned reviews were analyzed using Latent Dirichlet Allocation (LDA), which identified 18 key topics. These topics include environmental awareness, the role of waste banks, and the application of the 3R principles: Reduce, Reuse, and Recycle. The results indicate a relatively high level of public awareness, particularly in supporting waste banks and recycling efforts, which received the highest score of 4.23. However, the aspects of reduction and reuse still require further education. While cleaning facilities are considered sufficient, their maintenance remains suboptimal. The findings also show a growing public recognition of waste's economic potential, supported by a 4.44 score on the indicator for utilizing waste as an economic resource. The study concludes that the waste economy presents promising opportunities for advancing environmental and economic sustainability. To maximize these benefits, efforts should be focused on improving public education regarding reduction and reuse, along with enhancing the effectiveness and maintenance of waste management infrastructure. This research is limited to text-based data from Twitter, analyzed using the LDA model, with findings influenced by the coherence score applied. Moreover, the scope is centered on issues such as environmental awareness, waste banks, and 3R implementation, without addressing the technical or policy aspects of waste management in greater depth. © 2026
