To switch the over-reliance on fossil-based resources, curb environmental quality deterioration, and promote the use of renewable fuels, much attention has recently been directed toward the implementation of sustainable and environmentally benign 'waste-to-energy' technology exploiting a clean, inexhaustible, carbon-neutral, and renewable energy source, namely agricultural biomass. From this perspective, anaerobic co-digestion (AcoD) technology emerges as a potent and plausible approach to attain sustainable energy development, foster environmental sustainability, and, most importantly, circumvent the key challenges associated with mono-digestion. This review article provides a comprehensive overview of AcoD as a biochemical valorization pathway of crop residues and livestock manure for biogas production. Furthermore, this manuscript aims to assess the different biotic and abiotic parameters affecting co-digestion efficiency and present recent advancements in pretreatment technologies designed to enhance feedstock biodegradability and conversion rate. It can be concluded that the substantial quantities of crop residues and animal waste generated annually from agricultural practices represent valuable bioenergy resources that can contribute to meeting global targets for affordable renewable energy. Nevertheless, extensive and multidisciplinary research is needed to evolve the industrial-scale implementation of AcoD technology of livestock waste and crop residues, particularly when a pretreatment phase is included, and bridge the gap between small-scale studies and real-world applications.
为了改变对化石资源的过度依赖，遏制环境质量恶化，并促进可再生燃料的使用，最近人们将大量注意力投向了实施可持续且环境友好的“废物转化能源”技术，该技术利用一种清洁、取之不尽、碳中和且可再生的能源，即农业生物质。从这个角度来看，厌氧共消化（AcoD）技术成为实现可持续能源发展、促进环境可持续性的一种有力且可行的方法，最重要的是，它能规避与单一消化相关的关键挑战。这篇综述文章全面概述了AcoD作为一种用于生产沼气的作物秸秆和畜禽粪便生物化学增值途径。此外，本文旨在评估影响共消化效率的不同生物和非生物参数，并介绍旨在提高原料生物降解性和转化率的预处理技术的最新进展。可以得出结论，农业生产每年产生的大量作物秸秆和动物粪便代表了宝贵的生物能源资源，有助于实现全球可负担可再生能源目标。然而，需要进行广泛的多学科研究，以推动畜禽粪便和作物秸秆AcoD技术的工业化规模实施，特别是在包括预处理阶段的情况下，并弥合小规模研究与实际应用之间的差距。
