Abstract

The treatment of waste gaseous streams has become an important topic of environmental concern. One promising technology is electroabsorption which combines two important treatment processes into a single unit. In this sense, this review compiles the information available in the recent literature showing the hybridization of absorption units with electrochemical cells for treatment of gases polluted with volatile organic compounds and odorous substances. This approach is compared with other competing technologies, paying special attention to the technology readiness level. Although from the laboratory tests, it appears to be a promising methodology for the degradation of volatile organic compounds and environmental odorous gases; this critical review points out that more research is needed to raise the technology readiness level of this treatment technology in a context in which the society is demanding more and more sustainable technologies.
