As global climate change intensifies, reducing carbon emissions and promoting sustainable development have become crucial global priorities. Biomass, as a renewable and versatile resource, plays a critical role in reducing dependency on fossil fuels and enabling the transition toward a circular bioeconomy. Innovative biomass-based technologies allowing the production of biofuels, bio-based materials, and high-value biochemicals significantly enhance the sustainability of energy and materials.

By integrating biorefinery strategies, environmentally friendly extraction methods, and advanced thermochemical or biochemical conversion processes, biomass valorization not only supports carbon neutrality but also maximizes resource efficiency and reduces waste. As global demand for sustainable solutions increases, advanced biomass-utilizing strategies become essential to achieve a low-carbon future, strengthen environmental sustainability, and ensure long-term economic stability.

The goal of this Research Topic is to advance and disseminate cutting-edge research on the valorization of biomass feedstocks, emphasizing sustainable, efficient, and innovative biomass utilization approaches. Integrating new developments in biorefinery technologies, environmentally friendly extraction methods, bio-based materials, and renewable energy production, this Research Topic will contribute substantially to shaping circular bioeconomy strategies.

Key research areas include biopolymers, biofuels, hydrogen production, thermal insulation materials, and environmental impact assessments of biomass-derived products. By bridging scientific innovation and industrial application, this collection seeks to highlight emerging opportunities, address ongoing challenges, and significantly contribute toward sustainable and future-oriented solutions in energy and materials research.

The objective of this Research Topic is to highlight innovative, recent, and emerging advancements in biomass valorization. We welcome Original Research, Review, Mini Review, and Perspective articles focusing (but not limited to) the following themes:
