Evaluation of waste minimization in electroplating for cost saving

Along with many factories dump waste into Jakarta’s rivers, especially the Electroplating industries, cause river water quality to deteriorate. The serious problem is danger electroplating waste consisting of toxic compounds and accumulate in food chains, like zinc and cyanide. The purpose of this study was to evaluate waste management in the process electroplating with the concept of waste minimization and savings. This research method was quantitive by mass balance modeling and comparative study. The sample was taken by the composite way at 22 points (8 concentrates and 14 rinse water). Atomic Absorption Spectrometry (AAS) analysis read the results from the sample as data. The result of this study is the electroplating process need to modify with counter-current rinsing and apply pollutant load analysis. The conclusion is if the minimization of waste is applied, the cost savings obtained are IOR 392,964,436 or USO 27,941. Suggestions for the electroplating industry are to use environmentally friendly chemicals and to calculate the pollutant load first in the process flow (with the concept of waste minimization).Along with many factories dump waste into Jakarta’s rivers, especially the Electroplating industries, cause river water quality to deteriorate.
