Strategic valorization of readily available sugarcane bagasse (SB) is very important for waste management and sustainable biorefinery. Conventional SB pretreatment methods are ineffective to meet the requirement for industrial adaptation. Several past studies have highlighted different pretreatment procedures which are lacking environmentally benign characteristics and effective SB bioconversion. This article provides an in-depth review of a variety of environmentally acceptable thermochemical and biological pretreatment techniques for SB. Advancements in the conversion processes such as pyrolysis, liquefaction, gasification, cogeneration, lignin conversion, and cellulose conversion via fermentation processes are critically reviewed for the formation of an extensive array of industrially relevant products such as biofuels, bioelectricity, bioplastics, bio adsorbents, and organic acids. This article would provide comprehensive insights into several crucial aspects of thermochemical and biological conversion processes, including systematic perceptions and scientific developments for value-added products from SB valorization. Moreover, it would lead to determining efficient pretreatment and/or conversion processes for sustainable development of industrial-scale sugarcane-based biorefinery.
充分利用甘蔗渣(SB)进行战略增值对于废物管理和可持续生物炼制非常重要。传统的 SB 预处理方法无法满足工业适应性的要求。过去的几项研究强调了不同的预处理程序,这些程序缺乏环境友好的特点和有效的 SB 生物转化。本文深入回顾了各种可接受的环境的热化学和生物预处理技术 SB。对热化学转化过程(如热解、液化、气化、热电联产、木质素转化和纤维素发酵转化)的进展进行了批判性的回顾,以形成广泛的工业相关产品,如生物燃料、生物电能、生物塑料、生物吸附剂和有机酸。本文将全面了解热化学和生物转化过程的几个关键方面,包括系统感知和从 SB 增值中获得附加值产品的科学发展。此外,它将有助于确定有效的预处理和/或转化工艺,以实现基于甘蔗的工业规模生物炼制的可持续发展。
