Although there has been an official household waste recycling system in Taiwan, the system still works rather inefficiently because of problems such as resistance from citizens, political complexity, and those arising from culture. This study examines the antecedents of the behavior of household waste recycling in the context of an integrated model. This model incorporates a wide variety of important factors from previous research on environmental behavior into a single theoretical framework provided by the theory of planned behavior (TPB). This model was tested using data from a sample of 386 community residents in Kaohsiung, each of whom completed a survey. The results suggest that in addition to the TPB variables, perceived moral obligation further improved the prediction of intention to recycle household waste. Implications for operating household waste recycling systems are discussed.
