This study aims to measure the level of public acceptance regarding the use of transparent-walled waste bins, an innovation designed to enhance the effectiveness of waste sorting during Car Free Day (CFD) events in Denpasar City—specifically at Niti Mandala Renon City Park and Lumintang City Park. Employing a quantitative descriptive approach supplemented by qualitative data, the study gathered information through questionnaires and observations. A purposive sampling technique was used to select respondents, with the sample size determined via the Slovin formula, resulting in 127 participants. The level of acceptance for this innovation was assessed by integrating the Technology Acceptance Model (TAM) across three key variables: Knowledge (X1), Behavior (X2), and Opinion (X3). The findings indicate a highly positive linear correlation across all variables. Public knowledge levels fell within the 67–75% range (categorized as "good"), confirming that the facilities are easy to use. Regarding behavior, 79–80% of the public demonstrated actual discipline in sorting waste according to its classification. Furthermore, 57–60% of respondents provided positive evaluations concerning "perceived usefulness" and "perceived ease of use," although 12–15% expressed concerns that the bins might detract from the area's aesthetics if waste collection is delayed. Given that the majority of scores fall into the "good" category, it is concluded that the level of acceptance among the public in Denpasar City is high. These transparent waste bins have proven effective in evolving from mere physical receptacles into instruments of visual communication, fostering a sustainable shift in the public's waste-sorting habits.
