📄 Abstract（原文）
Global energy demand, currently exceeding 600 EJ annually, continues to rise alongside rapid electrification and industrial expansion, while renewable energy contributes only ~15% of total primary energy despite dominating recent capacity additions. This disparity indicates a critical gap, the need for scalable, carbon-neutral energy systems that not only generate power but also valorize waste streams. In this context, anaerobic bioprocessing offers a transformative solution by establishing a dual-pathway bioenergy framework through acidogenic/acetogenic and methanogenic routes. This review critically evaluates the distinct and complementary contributions of acidogenic/acetogenic and methanogenic pathways to green energy recovery. Acidogenic and acetogenic fermentations play a crucial role in sustainable waste management by efficiently converting complex organic materials into valuable biofuels such as green hydrogen and volatile fatty acids (SCCA/MCCA). This high-rate carbon unlocking not only enhances resource recovery (345–589 kg volatile fatty acids (VFA)/ton waste) but also contributes to energy generation (3–10.3 kg H2/ton waste; 334–1123 MJ), aligning with future energy demands and environmental sustainability goals in professional practices. These processes can enable product diversification in renewable fuels and chemicals, establishing a foundation for green chemistry and decentralized biorefineries. Advocating for further exploration and implementation of these pathways is essential for advancing sustainable practices in energy generation and resource management. In contrast, methanogenesis functions as the terminal energy-consolidation stage of anaerobic digestion (AD), transforming organic waste into biomethane (67–193 KgCH4/ton of waste), achieving energy recovery of 3368–9728 MJ, offering stability, scalability, and direct integration into existing energy infrastructures. Together, these pathways create a cohesive carbon and energy cascade, with acidogenic and acetogenic processes unlocking molecular value and flexibility, while methanogenesis ensures efficient energy recovery. This synergistic relationship promotes AD from simple waste treatment to a multi-output biorefinery platform, advancing zero-waste strategies, reducing the reliance on fossil fuels, and fostering resilient circular bioeconomies.
