POLLUTION BALANCE METHOD AND THE DEMONSTRATION OF ITS APPLICATION TO MINIMIZING WASTE IN A BIOCHEMICAL PROCESS

In this study, we introduced several, modifications to the WAR (waste reduction) algorithm developed earlier. These modifications were made for systematically handling sensitivity analysis and various tasks of waste minimization. A design hierarchy was formulated to promote appro priate waste reduction tasks at designated levels of the hierarchy. A sensitivity coefficient was used to measure the relative impacts of pr ocess variables on the pollution index of a process. The use of the WA R algorithm was demonstrated by a fermentation process for making peni cillin.
