Abstract
In the chemical industry, separation techniques typically have a significant environmental impact. This is especially true for solvent regeneration processes. The pharmaceutical industry generates a large amount of waste solvents, for the regeneration of which many technically effective methods have already been developed. These are the so-called physico-chemical processes, such as distillation, absorption, stripping, and membrane processes, etc. They require a lot of energy, so their greenhouse gas emissions are also significant. However, by combining the methods, they can be developed in the field. In the present research, the environmental impact of industrial case studies is evaluated by combining three areas: Life Cycle, PESTLE and Multi-Criteria Decision Analyses. The environmental assessment is expanded with the help of PESTLE factors, the Political, Economic, Social, Technological, Legal, Environmental aspects are also investigated in the case of the distillation treatment of pharmaceutical wastewaters and the dehydration of alcohols with hybrid separation processes (distillation combination with pervaporation).
