Abstract:

Anaerobic fermentation converts organic waste into valuable products like volatile fatty acids (VFA). However, this process has weaknesses, such as delayed mass transfer, a slow microbe growth rate, poor hydrolysis, and surface heterogeneity. Such issues can be addressed by adding nanomaterials because they have unique physicochemical properties, such as a large surface area, many active sites, a high level of reactivity, a high level of specificity, the ability to self-assemble, and better mobility. This review focuses on the current efforts to investigate the effects of nanomaterials on improving VFA production. In addition, this work includes bibliometric information to aid in understanding current trends in this field of study. Furthermore, this work also reviewed the cytotoxicity and ecotoxicity of nanoparticles, followed by the applications and downstream processing of VFA. Finally, this paper discusses the reuse and recovery of several nanomaterials and provides a cost analysis.
