Environmental life-cycle comparisons of two polychlorinated biphenyl remediation technologies: Incineration and base catalyzed decomposition

► We study the environmental impacts of two kinds of remediation technologies including Infrared High Temperature Incineration(IHTI) and Base Catalyzed Decomposition(BCD). ► Combined midpoint/damage approaches were calculated for two technologies. ► The results showed that major environmental impacts arose from energy consumption. ► BCD has a lower environmental impact than IHTI in the view of single score.
