A Bibliometric Analysis of Cellulose-Based Plastics from 1984 to 2024

Cellulose-based plastics have gained significant attention due to their biodegradability, renewability and potential to replace petroleum-based plastics. This study presents the first bibliometric analysis of global research trends on cellulose-based plastics using the Scopus database, covering the period from 1984 to 2024. A total of 395 documents were analyzed using VOSviewer software. The bibliometric analysis method included both quantitative information and qualitative data. The results show a significant surge in publication output over the last decade, highlighting growing interest in this field. China emerged as the leading contributor, followed by the United States and India. Cellulose was identified as the most productive journal, publishing 23 articles related to this topic. The most prolific authors included Xing Xiang Ji (China), Sabino De Gisi (Italy), Giovanni Gadaleta (Spain), and Michele Notarnicola (Italy). Keyword co-occurrence analysis revealed four dominant research themes: improving mechanical properties; application of cellulose-based plastics for food packaging; environmental assessment; and enhancing water and heat resistance. These themes reflect the dual emphasis on improving material performance and addressing ecological challenges. This study provides a clear overview of the research landscape, trends, and emerging topics in cellulose-based plastics research.
