Food waste (FW) management by biological process is more attractive and eco-friendly approach than thermo-chemical conversion or landfilling. However, FW composition and physico-chemical and biological characteristics affect the overall biological process in terms of product yield and degradation rate. To overcome this major bottle-neck, the pretreatment of FW is proposed. Therefore this review aims to provide a comprehensive summary of the importance of pretreatment of FW with respect to FW management by anaerobic digestion (AD) and dark fermentation (DF). It also reviews the existing knowledge gaps and future research perspectives for better integration of FW pretreatments for AD and DF, which should include (i) the preservation of carbon mass through freeze and thaw, or drying; and (ii) improve the carbon accessibility through particle size reduction and thermal pretreatments for high-rate bioenergy recovery.
与热化学转化或填埋相比，通过生物过程进行食物垃圾（FW）管理是一种更具吸引力和环保的方法。然而，FW 的组成、物理化学和生物特性会影响产品产量和降解率等整体生物过程。为了克服这一主要瓶颈，提出了 FW 的预处理。因此，本综述旨在全面总结 FW 预处理在厌氧消化（AD）和暗发酵（DF）方面的 FW 管理中的重要性。它还回顾了现有的知识空白和未来的研究观点，以更好地整合 AD 和 DF 的 FW 预处理，这应包括（i）通过冷冻和解冻或干燥来保存碳质量；和（ii）通过减小粒径和热预处理来提高碳的可及性，以实现高速生物能源回收。
