Sugarcane Bagasse as a Renewable Energy Resource: A Bibliometric Analysis of Global Research Trends

Abstract

Sugarcane bagasse (SCB), a fibrous residue generated during the sugar and ethanol production process, has attracted growing global interest due to its promising applications in renewable energy systems. This study presents a comprehensive bibliometric analysis of international research trends related to SCB from 2005 to 2024 using data from 26,663 documents retrieved from the Web of Science database ultimately refined to 657 relevant publications. The analysis identifies Brazil, India, the United States, and China as the leading contributors in this field, reflecting their strategic investments in biomass research, energy policy, and technological development. By synthesizing key findings from the literature, the study offers insights into SCB’s multifaceted role in renewable energy, including its use in bioenergy conversion processes and biofuel generation, as well as a precursor for developing catalysts and advanced materials. Furthermore, the results highlight the importance of SCB valorization in mitigating greenhouse gas emissions, promoting circular economy practices, and accelerating the global transition toward sustainable and low-carbon energy systems. By integrating bibliometric tools and quantitative analysis, this study provides a detailed overview of the evolution, current landscape, and future directions of SCB-related research.
