Abstract

The renewable energy sector is undergoing a revolution, driven by the need for sustainable resources. Among these, sugarcane bagasse (SCB) stands out as a promising candidate for bioenergy, capable of generating electricity, bioethanol, and biogas. However, SCB storage and utilization face significant challenges due to its high moisture content (48–52%) after sugarcane crushing. This review explores the limitations of conventional SCB drying methods and introduces solar drying as an energy-efficient and eco-friendly alternative.

The conversion of SCB to bioethanol is further complicated by its recalcitrant structure, necessitating costly and sometimes toxic pre-treatment processes. This comprehensive study examines the current landscape and advancements in SCB pre-treatment techniques during bioenergy production. Additionally, it discusses innovative strategies to optimize cogeneration systems, aiming to boost surplus power export to the grid. By shedding light on these cutting-edge developments, this review aims to inspire further research and innovation in the quest for sustainable bioenergy solutions.

利用甘蔗渣生产生物能源：现状、优化和未来方向

在可持续资源需求的推动下，可再生能源领域正在经历一场革命。在这些资源中，甘蔗渣（SCB）是一种很有前途的生物能源，能够发电、生产生物乙醇和沼气。然而，由于甘蔗粉碎后含水量高（48-52%），甘蔗渣的储存和利用面临着巨大挑战。这篇综述探讨了传统甘蔗渣干燥方法的局限性，并介绍了太阳能干燥这种节能环保的替代方法。甘蔗渣的结构不易降解，这使得将其转化为生物乙醇的过程更加复杂，因此必须采用成本高昂、有时甚至有毒的预处理工艺。本综合研究探讨了生物能源生产过程中 SCB 预处理技术的现状和进展。此外，它还讨论了优化热电联产系统的创新战略，旨在促进向电网输出剩余电力。通过揭示这些前沿发展，本综述旨在激励在寻求可持续生物能源解决方案方面的进一步研究和创新。
