Volatile organic compounds (VOC) are major contributors to the burgeoning air pollution issue, predominantly from industrial areas, with well-documented environmental and health risks, which demand efficient sustainable control policies. This review analyzes current technological challenges investigates recent developments in biological treatment technologies for VOC-contaminated off-gases, including biofilters, biotrickling filters, bioscrubber, as well emerging technologies, such bioaugmentation microbial fuel cells (MFCs). Operational performance, economic feasibility, adaptability various applications assessed, alongside opportunities integration other energy recovery technologies. Biological systems offer considerable advantages regarding cost savings lower impacts enhanced operational flexibility, particularly when combined innovative materials optimization techniques. Nevertheless, persist, choosing best settings suited different VOC streams addressing biofilm concerns scalability. Overall, treatments encouraging solutions, though continued research into reactor design, dynamics, MFC-based energetic valorization is essential broader application. These insights cover advancements highlight continuous need prowess forge control.
