The performance of waste-extracted natural dyes and mordants with respect to the environment has been verified and suggested to be comparable to the traditional mordants containing heavy metals. It is interesting to perceive that the COD/BOD 5 ratio of these natural dyes is approximately 2, which is an aspired ratio for effluent treatment. Moreover, the absence of restricted heavy metals in natural mordants enhances their application in dyeing process. In a nutshell, the potential for developing natural dyes and mordants are unlimited.
