Abstract

The separate collection and recycling of used cooking oil (UCO) as biodiesel fuel for use as an alternative to fossil fuels can reduce the environmental burden. Therefore, the establishment of a system to recycle UCO from households is urgently needed.; hence, it is critical to analyze the information that need to be provides to raise the participate rate of waste separation behavior of UCO. In order to clarify the content of information that should be provided to improve UCO’s separation collection according to differences in usual pro-environmental behavior (PEB) and environmental risk perception, this study analyzed 2,380 people who did not participate in the UCO’s separate collection by adding the explanatory variable “provision of information” to the Theory of Planned Behavior (TPB) model in Japan. The policy implications of this study for accelerating the separate collection of UCO are as follows. First, for those who lacked environmental risk perception or did not usually engage in PEB, information on the benefits of improving environmental problems through the separate collection of UCO was more effective than information on how to separate collection of UCO in increasing their intention to participate in future UCO’s separate collection. Second, although information on the effects of the separate collection of UCO on the environment is more effective than information on the method of separate collection of UCO, it was also confirmed that information on the method of separate collection of UCO encourages the formation of the intention to participate in the UCO separate and collection.
