| Abstract: | A comparison of various waste-solvent treatment technologies, such as distillation (rectification) and incineration in hazardous-waste-solvent incinerators and cement kilns, is presented for 45 solvents with respect to the environmental life-cycle impact. The environmental impact was calculated with the ecosolvent tool that was previously described in Part I of this work. A comprehensive sensitivity analysis was performed, and uncertainties were quantified by stochastic modeling in which various scenarios were considered. The results show that no single treatment technology is generally environmentally superior to any other but that, depending on the solvent mixture and the process conditions, each option may be optimal in certain cases. |
