In this study the carbon footprint and power demand of tannery wastewater treatment processes for the largest bovine leather producing regions were quantified and analysed. Moreover, we present a case in which we benchmarked the carbon footprint and energy demand analysis of tannery wastewater treatment to municipal wastewater treatment. We quantified the greenhouse gas direct and indirect emissions from tannery wastewater treatment facilities. Our results show that the total CO2-equivalent emission for tannery wastewater treatment is 1.49 103 tCO2,eq dâ1. Moreover, the energy intensity of tannery wastewater treatment processes are evaluated at 3.9 kWh kgâ1bCOD,removed, compared to 1.4 kWh kgâ1bCOD,removed of municipal wastewater treatment processes. Based on this work in the field of tannery wastewater treatment, an effort to innovate suitable treatment trains and technologies has the strong potential to reduce the carbon footprint.
