Geographical representativeness description
|
"China is the world's largest production base for printing and dyeing, but rapid development is accompanied by severe environmental issues. Currently, the printing and dyeing industry primarily addresses environmental problems through clean production audits, implementing research on low-toxicity and low-pollution raw materials, resource utilization of waste, equipment upgrades and renovations, recycling of water and steam, and improvements in production processes. However, existing clean production schemes often focus on specific environmental issues without considering the interconnections between industrial systems."

Use advice for data set
| The data set does not include transportation to the final disposal site due to the uncertainty of the location of product consumption and final disposal. The final disposal process is based on a disposal model of a city in China and does not account for energy consumption during the disposal process due to a lack of reliable data. The assumptions made are that the proportions of sanitary landfill and incineration as disposal methods are equal, each at 50%. Caution should be exercised when applying this data to life cycle assessments as transportation and energy consumption during disposal could significantly affect the overall environmental impact profile of the cotton product lifecycle. Methodological choices and assumptions like these should be properly justified in the study context. |
|
Technical purpose of product or process
| The wet steaming cotton dyeing and finishing process is applied to the textile industry, specifically for processing printed and dyed cotton fabrics. These fabrics are often used in the production of clothing, home textiles, and other cotton-based products. After consumer use, the cotton material is eventually directed to final disposal, which includes sanitary landfill as one of the methods. |

| "Due to uncertainties in product consumption and the ultimate disposal location, this study omits the transportation process from the research subject to the final disposal site. The final disposal process of the product is based on a disposal model in a specific city in China (Yang Jianxin, Xu Cheng, Wang Rusong. Methods and Applications of Life Cycle Assessment [M]. Beijing: Meteorological Press, 2002, 6.). Due to a lack of sufficiently reliable data, this study neglects energy consumption in the final disposal process of the product and assumes an equal distribution of sanitary landfilling and incineration, each accounting for 50%." |
