Theory of Planned Behavior Modeled Educational Technology for Waste Management Learning

Responsible waste management is important for our sustainable living. However, there are still many challenges ahead, such as properly sort the wastes. In this paper, we conducted a Theory of Planned Behavior (TPB)-based study to understand the impact of waste management literacy on people's intentions. Our results indicate that increasing the literacy level can positively influence people's intentions to actively sort their wastes. Additionally, we also proposed a mobile application that includes an intelligent Waste Detect Engine (WDE) and a Waste management Knowledge Agent (WMKA) to facilitate people learn. In a subsequent user study, we observed a significant improvement in users' waste sorting knowledge with the assistance of the proposed educational technology.
