Literature mapping of waste sorting and recycling behavior research: a visual analysis using CiteSpace

As the severity of global waste pollution continues to escalate, governments are increasingly prioritizing the promotion of waste sorting. This study engaged in the literature mapping of waste sorting and recycling behavior research currently available on the Web of Science using CiteSpace. First, studies on waste sorting behavior have grown rapidly since 2017. The top three continents publishing on this topic were Asia, Europe, and North America. Second, the top journals, Resources Conservation and Recycling and Environment and Behavior, were important to this field. Third, analyses of waste sorting behavior were mainly conducted by environmental psychologists. Ajzen had the highest co-citation count, as the theory of planned behavior has widely been used in this field. Fourth, the top three co-occurring keywords were "attitude," "recycling behavior," and "planned behavior." There was also a recent focus on "food waste." The research trend was found to be refined and accurately quantified.
