Abstract
Due to uncertainties in water supply, there is growing demand for water resource management in enterprises. In this study, we evaluated the effects of companies’ water-saving reconstruction projects. We used Hina Advanced Materials Company as a case to construct an investment decision model to (1) calculate the internal and external costs of water resources based on circular economic value analysis theory, and (2) locate the level of water resources circulation. We adopted gray situation decision analysis to identify the typical problems that occur in water resource utilization. Moreover, we demonstrated optimization plans for different potential improvements, thereby providing guidance and references for water resource cost management and the comprehensive optimization of environmental benefits. We concluded that the circulation economic value analysis model can effectively display the flow and amount of value derived from water resource flows, thereby providing guidance and suggestions for optimizing water resource flows.
Highlights
Half of China’s water resources are substantially polluted as urbanization accelerates and industrial sewage is discharged irresponsibly
The ternary materials industry has received widespread attention from the public due to the massive amount of wastewater discharged from its production processes which results in significant environmental pollution
These studies analyze the vertical expansion based on the calculation results of corporate resource value flow (e.g., Live Intrinsic Material Estimation (LIME) evaluation system of resource value circulation, evaluation systems based on analytic hierarchical process (AHP), and gray situation decision-making) (Xiao and Xiong, 2010; Zheng and Xiao, 2010)
Summary
Half of China’s water resources are substantially polluted as urbanization accelerates and industrial sewage is discharged irresponsibly. The ternary materials industry has received widespread attention from the public due to the massive amount of wastewater discharged from its production processes which results in significant environmental pollution. This industry has a water consumption of 10 tons per ton of product and a low utilization rate of water recycling. In this study we attempt to optimize the ternary materials industry using water resource value flow analysis to improve the economic benefits of water resources.
