An AHP-based water-conservation and waste-reduction indicator system for cleaner production of textile-printing industry in China and technique integration

Abstract

The textile-printing industry in China makes an important contribution to the national economy. However, the associated pollution problems have caused gradual deterioration to the environment and adverse impacts on the local community. The indicator system of cleaner production gives a powerful tool to measure the level of cleaner production of textile-printing enterprises. In China, it has been a big problem of the textile-printing enterprise that consuming large amounts of fresh water and discharging large number of pollutants, and it is lacking in a scientific water-conservation and waste-reduction cleaner production evaluation system. To solve such problems, the establishment of water-conservation and waste-reduction cleaner production indicator system in textile-printing industry is proposed and assessed by the means of analytic hierarchy process (AHP) in this article. The judgement matrix is then determined with the Delphi Method combined. Finally, with the Yaahp software, the weight of each indicator is obtained. As an effective way to save water resource and reduce waste emission, the cleaner production technique integration is provided for the enterprises to solve the above problems and achieve the goals of saving water and decreasing the amount of disposed pollutants.
