📄 Abstract（原文）

Renewable energy is critical for reducing dependence on fossil fuels and mitigating climate change. Biomass is a widely available renewable resource with carbon-neutral potential, enabling conversion of organic residues into energy. Common biomass solid-fuel feedstocks include agricultural residues, forestry residues, municipal organic waste, algal biomass, and energy crops. This review examines sustainable biomass solid fuels from the integrated perspectives of feedstock sources, processing technologies, and circular-economy utilization pathways. Particular emphasis is placed on how compositional characteristics (proximate/ultimate properties, HHV, etc.) govern conversion behavior and final fuel quality. Recent advances in hydrothermal carbonization, pyrolysis, densification, and additive-assisted upgrading are systematically summarized, with attention to their effects on carbon enrichment, energy density, pore structure, and combustion performance. Unlike previous reviews that discuss feedstocks and conversion routes separately, this review explicitly connects biomass source characteristics with process design, fuel upgrading, and sustainability outcomes. It further highlights how biomass solid fuels can support circular-economy strategies by valorizing waste streams, reducing disposal burdens, supporting rural development, and promoting low-carbon energy systems.
