Abstract The viscose fiber industry forms a large part of the textile industry and is a typical water consumption and wastewater discharge industry. As a tool to quantify environmental impacts in terms of water resources, the water footprint assessment (WFA) is a control method for the textile and apparel industry to measure water consumption and wastewater discharge. In this study, the water footprints of viscose staple fiber blouses and blended men's suits were comprehensively evaluated based on the ISO 14046 standard and the life cycle assessment (LCA) polygon method. The WFA results from our study indicate that the production stage of viscose staple fiber garments has the most significant water resource environmental load. Specifically, the water footprint related to the production of viscose staple fiber for three types of clothing accounted for more than 50% of the total water footprint, with men's 100% viscose staple fiber suits having the largest impact on water resources and the environment. Furthermore, our results indicate that the water alkaline footprint is primarily influenced by the viscose staple fiber production as well as the dyeing and finishing processes. NaOH and Na2CO3 are the main pollutants that caused the water alkaline footprint. In addition, the water ecotoxicity footprint was the major driving factor of water resource environmental load. Zn2+ is the main pollutant that caused the water ecotoxicity footprint.

Pillar Industry

As a traditional pillar industry in China, the textile industry has been intensifying the pressure of the water resource load and its reduction of water environment emissions over the years. Decoupling water resource consumption and wastewater discharge require decoupling from economic growth to realise the sustainable development of the textile industry. On the basis of water footprint and decoupling theories, this paper analysed the water consumption decoupling, wastewater discharge decoupling, as well as the double decoupling of water consumption and wastewater discharge of China’s textile industry and its three sub-industries (Manufacture of Textile, Manufacture of Textile Wearing and Apparel, Manufacture of Chemistry) from 2001 to 2015. In those years, the sum of the decoupling index in the double-decoupling years is 249, lower than that in high-decoupling years of water consumption (250) and wastewater discharge (325). Compared with the decoupling of water consumption and of wastewater discharge, the double decoupling is lower, which proves that the conditions for realizing double decoupling are stricter. The double decoupling analysis of water consumption and wastewater discharge, namely, the overall consideration of water resource consumption and water environment pollution, could be used to more effectively promote the realisation of water decoupling in the textile industry.

The awareness of the fact that the leading cause of the bad environmental conditions in our world is the human factor, has been increasing in recent years. This awareness enables people, companies, and organizations to decrease water consumption, to decrease carbon emission, to decrease using harmful chemicals, consequently people who are aware of global warming and depletion of resources are taking actions to save our planet for a sustainable life. Textile is one of the big sectors affecting the environmental pollution in a very bad way. For that reason, the present water footprint research was conducted on textiles and a denim company was especially chosen to examine the water footprint because of denim sector’s being one of the biggest polluters and wasting water in a huge amount in the textile industry. Firstly, the limits of the research were obtained as finishing operations under the scope of water footprint. The production steps and wastewater occurring points were obtained carefully for different denim finishing processes. After that stage, personal water consumption during denim apparel production was examined in detail. To create a good inventory analysis, many meetings were performed, and a survey was prepared to collect the data about wastewater of the company. By the help of this water footprint evaluation, the processes that create the most wastewater and the distribution of water footprint according to processes and other sources that cause water consumption were determined for one pair of denim trouser accepted as a functional unit in the context of the research.

The Cost

The Resource Tax Law was officially implemented on September 1, 2020, in China. This law presents the “Fee-to-Tax” reform of water resources. This article compares the effects of the “Fee-to-Tax” reform under asymmetric duopoly conditions with perfect information. The mechanisms of the two policies are different when all firms simultaneously respond to water resources: the water resource fee affects output by reducing market size, while the water resource tax reduces output by amplifying the weighted cost difference effects between companies. Water resource taxes work better than fees for eliminating backward production capacity. A comparison of the situation when companies respond sequentially is also carried out. When a low-cost firm is in the leading position, the collection of fees actually reduces the output difference, whereas the tax improves it. When a high-cost firm acts as a leader, the effects depend on the cost difference. When the cost difference between firms is small, the first-move advantage of high-cost firms dominates the cost advantages of low-cost firms. Therefore, a higher tax rate yields a smaller output difference. When cost differences are relatively larger, the cost advantage of low-cost firms dominates the first-move advantage of high-cost firms. As the operational cost for reducing water consumption increases, the reduced water consumption first increases and then decreases.

Factors Influencing

Scientifically determining agricultural water consumption is fundamental to the optimum allocation and regulation of regional water resources. However, traditional statistical methods used for determining agricultural water consumption in China do not reflect the actual use of water resources. This paper determined the variation in the crop water footprint (CWF) to reflect the actual agricultural water consumption in Xinjiang, China, during the past 30 years, and the data from 15 crops were included. In addition, the STIRPAT (stochastic impacts by regression on population, affluence and technology) model was used to determine the factors influencing the CWF. The results showed that the CWF in Xinjiang increased by 256% during the 30-year period. Factors such as population, agricultural added value, and effective irrigated area were correlated with an increase in the CWF. This study also showed that the implementation of national and regional policies significantly accelerated the expansion of agricultural production areas and increased the amount of agricultural water used. The objectives of this paper were to identify the factors influencing the CWF, give a new perspective for further analysis of the relationship between agricultural growth and water resources utilization, and provide a reference for local policy decision-makers in Xinjiang.
