dc.description.abstract | Water is the one of the three elements for sustaining the lives of humans, and it is an important natural resource in maintaining the process of the country’s economic and social development. More than 97% of water on earth cannot be directly used, therefore the fresh water resources that can be actually used accounts for less than 0.5%, which is very scarce. In recent years, due to the increase in water demand driven by economic and rapid population growth, and taking into account the factors contributing to environmental destruction and climate change and so on, the problem of water supply has worsened day by day. This study focuses on the issues of international water shortage, conducts research and discussion on the proposed concept of water footprint, takes the existing Water Footprint Assessment Manual announced by WFN most frequently cited in the country as an assessment tool, selects the domestic case of the CFP Factory (printed circuit board - FPC) as an inventory tool to investigate the water footprint within each production process, and conducts the comparison analysis by the inventory results, so as to learn the actual water distribution within the processes of a printed circuit board, and propose the water-saving improvement suggestions based on the results. The results show that the total water footprint of the annual products of the flexible printed circuit board factory is 0.019m3/pcs, wherein the blue water footprint is 0.017m3/pcs, which occupies 89.47% of the total water footprint; the gray water footprint is 0.002m3/pcs, which occupies 10.53% of the total water footprint; while the green water footprint is 0, as this case did not use the green water footprint as process production water supply.From the further discussion and analysis on the water footprint of a single month process and each machine process as well as the results after discussing the industry’s inventory, it can be learned that the water footprint of blue water is much larger than that of gray water, with the proportion occupied at more than 80%, compared with other industries. This shows that the water resources used in the production process of the industry in the case study takes up a larger proportion. The study expects to obtain the water distribution and characteristics in the flexible printed circuit board industry by water footprint inventory. This can be provided for the related enterprises as a reference in the planning and management of water resources, and realize the importance of water resources, so as to conduct effective planning in advance to reduce the risks and effects caused by the shortage of water resources. | en_US |
