Harnessing wood waste for sustainable biofuel: A bibliometric analysis and review of valorisation strategies

Abstract

This study provides a comprehensive bibliometric analysis of research trends in wood waste valorisation, focusing on key areas such as biofuel production, biochemical processes, and the integration of sustainability practices. The data reveals that China, the United States, and Canada are leading contributors in terms of both document output and citations, reflecting their significant roles in advancing the field. The analysis highlights the growing importance of integrated approaches, combining biochemical and thermochemical processes to optimize the conversion of wood waste into valuable bio-products. Co-occurrence network visualization of keywords indicates a strong focus on biofuel production, biochar, and circular economy principles, suggesting these areas will be central to future research directions. The study concludes that the field is set for considerable growth, with future research likely to emphasize scaling technologies, improving biochar applications, and fostering cross-disciplinary collaborations to enhance the sustainability and economic viability of wood waste valorisation. This research underscores the pivotal role of wood waste in the emerging bioeconomy, offering insights into future trends and opportunities for innovation.
