The anaerobic digestion is a well-established process for the treatment of organic solid waste, pursuing its conversion into a methane rich gas destined to energy generation. Research has largely dealt with the enhancement of the overall bioconversion yields, providing several strategies to maximize the production of bio-methane from the anaerobic processing of a wide variety of substrates. Nevertheless, the valorization of the process effluents should be pursued as well, especially if the anaerobic digestion is regarded in the light of the circular economy principles. Aim of this work is in identifying the state of the art of the strategies to manage the digestate from the anaerobic processing of the organic fractions of municipal solid waste. Conventional approaches are described and novel solutions are figured out in order to highlight their potential scale up as well as to address future research perspectives.
厌氧消化是一种成熟的有机固体废物处理工艺，旨在将其转化为富含甲烷的气体，用于能源生产。研究主要集中在提高整体生物转化产率上，提供了多种策略来最大程度地从各种底物的厌氧处理中生产生物甲烷。然而，也应该追求该工艺流出物的增值利用，特别是如果将厌氧消化视为循环经济原则的话。本文的目的是确定管理城市固体废物有机部分厌氧处理后消化物的策略的最新技术状态。描述了常规方法，并提出了新的解决方案，以突出其潜在的放大规模，并解决未来的研究方向。
