But the other angle of industrialization has been the serious damage to the surrounding environment so there is keen need of “Cleaner Production” to sustain against waste from industries and pollution. In this paper Cleaner Production(CP) methodology for a dye intermediate Pamino azo benzene 4-sulfonic acid(PAAB4SA) is described. The literature review on cleaner production tools is described. The paper discussed reactor design and simulation of it in the production of PAAB4SA. This modified design is cost saving and it also gives cleaner and easy operation. The paper describe COD reduction options for the case study of dye intermediate sulfotobias acid. Different methods are evaluated and compared to give cost effective method of COD reduction for the process. Experiments were performed for Sulfotobias acid with Advance oxidation process(AOP) of fenton reagent and adsorption using low cost adsorbent neem leaves powder. The detail process and experimental data are discussed in the paper.
