EVALUATION AND ACTIONS OF CLEANER PRODUCTION IN GALVANIC INDUSTRY OF THE VILLA CLARA PROVINCE

Abstract

In this paper, the assessment results accomplished in different processes of the galvanic industry are presented and it is taking into account the application of good practices and measures of Cleaner Production. The main critical points in the processes of metallic coating were identified; and the characterization of the effluents generated by the installation is done. A number of technological changes in the processes are proposed, as well as the introduction of cleaner production measures which contribute to increase the efficiency and safety of processes, reduce risks and improvements to internal operations. It provides advantages of economic, environmental and social nature for the galvanic industry due to the minimizing of the impacts on environment, because the sewage and its pollutant load are reduced. Besides, we can save water, energy and raw materials.
The economic evaluation showed the feasibility of applying the Cleaner Production (PML) measures proposed with a Net Present Value (NPV) of $109 696.26, and an Internal Rate of Return (IRR) of 64 % value and payback period lower than two years.
