Reviving Household Behavior Toward Waste: Driven Factors of Responsible Consumption

Environmental conditions are becoming increasingly critical due to the high volume of waste, with households contributing 61% of the total. The complexity of the waste issue poses significant challenges to achieving the Sustainable Development Goals (SDGs). This study intends to predict household waste-related behavior by proposing a novel approach that integrates the Theory of Planned Behavior (TPB) with responsible consumption. Data were gathered from 404 Indonesian households using a Likert scale questionnaire and analyzed using Structural Equation Modeling (SEM)-AMOS to assess the structural model. The results reveal that attitudes, perceived behavioral control, intention to sort waste, and responsible consumption significantly influence household waste behavior. Additionally, responsible consumption does not significantly moderate the effect of perceived behavioral control on waste sorting engagement but does significantly enhance the development of waste sorting behaviors. This study is unique in its integration of TPB with responsible consumption to predict waste behavior, particularly within the context of Indonesia, where demographic and psychographic factors contribute to high levels of waste generation.
