In the recent past, an increasing interest is mostly observed in using microwave and ultrasonic irradiation to aid the biological conversion of waste materials into value-added products. This study is focused on various individual impacts of microwaves and ultrasonic waves for the treatment of biomass before the synthesis of value-added products. Following, a comprehensive review of the mechanisms governing microwaves and ultrasonication as the treatment methods, their effects on biomass disruption, solubilization of organic matter, modification of the crystalline structure, enzymatic hydrolysis and production of reducing sugars was performed. However, based on the lab-scale experiments evaluated, microwaves and ultrasonication were studied to be economically and energetically ineffective despite their beneficial effects on the waste biomass. This article reviews some of the difficulties associated with using microwaves and ultrasonic irradiation for the efficient processing of waste biomasses and identified some potential directions for future study.
在最近一段时间，人们越来越关注利用微波和超声波辐射来辅助将废物转化为增值产品的生物转化。本研究主要集中在微波和超声波在合成增值产品之前对生物质进行处理的各种单独影响上。随后，对作为处理方法的微波和超声处理的机制、对生物质破坏、有机物溶解、结晶结构改性、酶水解和还原糖生产的影响进行了全面综述。然而，根据评估的实验室规模实验，尽管微波和超声波对废生物质有有益的影响，但它们在经济和能源方面是无效的。本文综述了使用微波和超声波辐照高效处理废生物质所面临的一些困难，并确定了未来研究的一些潜在方向。
