Abstract:

In ordet to improve the water resource management for the indrustrial prodrction of textiles and apparel with water footprint methodology, the concept of industrial water footprint of textiles and apparel was introduced firstly. Then the key issues, including calculation boundary, calculation method, allocate principle of integrate data and assessment benchmark, in the calculation and assessment benchmark, in the calculation and assessment of industrial water footprint of textiles and apparel were discussed in detail. In light of the characteristics of fresh water consumption and waste water discharge in textiles and apparel industrial production processes, it was considered that the time boundary and input-output boundary must be defined before the calculation of industrial water footprint. Direct industrial water footprint is the key point of the calculation. Wastewater recycling can reduce blue industrial water footprint effectively and original grey industrial water footprint is the direct indicator of the environmental loads caused by industrial wastewater. Allocate principles with yield or value can increase the accuracy of the calculation results. The internal assessment is more meaningful for the reduction of fresh water consumption and pollutants emission for the specific product.

Key words: textile and apparel, industrial water footprint, calculation boundary, calculation method, allocate principle, assessment benchmark
