Pollutants Generated from Pharmaceutical Processes and Microwave Assisted Synthesis as Possible Solution for their Reduction-A Mini Review

In this review article we have briefly summarized the pharmaceutical processes and the pollutants i.e., VOCs and other air emissions from reactors and distillation assemblies, polluted solvents released in water and solid wastes etc. generated due to conventional processes involved in preparation of pharmaceuticals. Medicines are prepared for the better health and to decrease the mortality rate in human beings but the conventional processes involved in preparation of these pharmaceuticals generate chemical and thermal pollution in environment, thus, giving rise to some other severe health impacts and ultimately increase the disease and mortality rate in human beings. Thus, we have discussed the sustainable technology of microwave as possible solution for the preparation of pharmaceuticals without the generation of pollutants. Some practical examples for the preparation of pharmaceuticals via microwave and conventional processes are also discussed and compared herein showing the benefits of using microwave technology over conventional process in terms of better yield and ecofriendly approach without using hazardous solvents.
