Volatile organic compounds (VOCs) have become a major concern that requires a viable and sustainable remedy as a substitute for conventional air pollution control technologies. This review follows the trend of biological VOC treatment, from the development of conventional biofilter systems to sophisticated biocatalytic systems. It also looks into the principles of VOC biodegradation and the importance of microbial communities, as well as the technology development of reactors such as biofilters, biotrickling filters, and hybrid biological systems. The efficiency and stability of biological treatment systems have been improved recently by material science, microbial resource engineering, and molecular biology, resolving the mass transfer limitation, microbial instability, and complexity of treating complex VOC mixtures. Nevertheless, technical bottlenecks, including fouling, clogging, and the formation of by-products, still hinder large-scale industrial use. The environmental trade-offs related to the treatment of biological VOCs mentioned in this article are the formation of toxic intermediates and the emission of greenhouse gases. However, with such challenges, process intensification, intelligent monitoring, and hybrid systems have been proposed to provide some promising directions toward limiting these constraints. The future of biological VOC treatment lies in its potential for combination with engineering innovations and biological processes, which will guarantee its scalability and long-term sustainability in atmospheric emissions management.
