Anaerobic digestion (AD) has the potential to catalyse the shift from a linear to a circular economy. However, effective treatment and management of both solid (DSF) and liquid (DLF) digestate fraction treatment and management require adopting sustainable technologies to recover valuable by-products like energy, biofuels, biochar, and nutrients. This study reviews state-of-the-art advanced technologies for DSF and DLF treatment and valorisation, using life cycle assessment (LCA) and techno-economic analysis (TEA) in integrated digestate management (IDM). Key findings highlight these technologies' potential in mitigating environmental impacts from digestate management, but there's a need to improve process efficiency, especially at larger scales. Future research should prioritize cost-effective and eco-friendly IDM technologies. This review emphasizes how LCA and TEA can guide decision-making and promote sustainable agricultural practices. Ultimately, sustainable IDM technologies can boost resource recovery and advance circular economy principles, enhancing the environmental and economic sustainability of AD processes.
厌氧消化 (AD) 有潜力推动经济从线性向循环经济转变。然而，要有效地处理和管理固体（DSF）和液体（DLF）消化物，需要采用可持续技术来回收有价值的副产品，如能源、生物燃料、生物炭和营养物质。本研究通过生命周期评估 (LCA) 和技术经济分析 (TEA) 在综合消化物管理 (IDM) 中，综述了 DSF 和 DLF 处理和增值的最先进的高级技术。主要研究结果强调了这些技术在减轻消化物管理对环境影响方面的潜力，但需要提高工艺效率，特别是在较大规模上。未来的研究应优先考虑具有成本效益和环保效益的 IDM 技术。本综述强调了 LCA 和 TEA 如何指导决策并促进可持续农业实践。最终，可持续的 IDM 技术可以促进资源回收和循环经济原则，提高 AD 过程的环境和经济可持续性。
