Data envelopment analysis as a tool to assess the water demand minimization potential in industrial zones in the Vietnamese Delta
This work employs the data envelopment analysis technique to assess the water use efficiency of companies and the water reduction potential of industrial categories in industrial zones. Fifty-eight companies were selected from four industrial categories: wearing apparel (WA,18), fabricated metal (FM,12), rubber and plastic (RP,12), and other manufacturing (OM,12) based on six variables: monthly water usage, two types of effluent contaminant loadings, monthly production capacity, number of employees, and surface occupied by a company. The results indicate that significant numbers of companies are inefficient in water use, namely WA(28%), OM(42%), FM(43%), and RP(46%). Implementing technical measures to improve water use efficiency at these companies offers a varying water reduction potential per industrial category, namely in the order RP(25%) > FM(17%) ≫ WA(7%) > OM(4%). These results show that improving water efficiency by water use minimization is not the only ptential measure for improving the industrial zone's water metabolism towards self-sufficiency.
期刊介绍：
Water Resources and Industry moves research to innovation by focusing on the role industry plays in the exploitation, management and treatment of water resources. Different industries use radically different water resources in their production processes, while they produce, treat and dispose a wide variety of wastewater qualities. Depending on the geographical location of the facilities, the impact on the local resources will vary, pre-empting the applicability of one single approach. The aims and scope of the journal include: -Industrial water footprint assessment - an evaluation of tools and methodologies -What constitutes good corporate governance and policy and how to evaluate water-related risk -What constitutes good stakeholder collaboration and engagement -New technologies enabling companies to better manage water resources -Integration of water and energy and of water treatment and production processes in industry
