Bibliometric Analysis of Liquid Biofuel from Phoenix dactylifera (Date Palm) Waste

Lignocellulosic wastes, and their conversion into value-added products such as bioethanol have been the subject of many research. This study aimed to carry out a bibliometric analysis of the most numerous scientific works on the production of ethanol from date waste. Using the Scopus database, VOSviewer and Citespace visualization software, this study analyzed 317 articles published between 2014 and 2023 on bioethanol production from dates. The results showed that the number of articles published between 2014 and 2023 reflects the growing interest in this field of research. Abasaeed Ahmed Elhag is the most prolific author who has published 8 articles in this field. Biotechnology for Biofuels is the most productive journal, with 16 publications. Renewable and Sustainable Energy Reviews, on the other hand, achieved the highest number of citations (588), underlining its impact and influence in the field of renewable energy research. The results of the study also showed that the United States is the most productive country in this field, with 172 publications reflecting the significant interest in, and investment in, renewable energy research in this country. The main themes and approaches used in the research on bioethanol production from dates are ethanol, fermentation, biomass and Saccharomyces cerevisiae. The analysis showed a positive trend in research in this field. However, there is a need to broaden our knowledge of new technologies for the bioconversion of biomass into energy products, and to integrate new biomasses in order to overcome the obstacles, integrating this field into sustainable development.
