| Résumé : |
Water is found everywhere on Earth, from the polar ice caps to steamy geysers. It is a vital source for all known forms of life.
Its presence and quality sets conditions for human settlements, economic development and ecosystems. According to WWF, 1.1 billion people worldwide lack access to water and a total of 2.7 billion find water scarce for at least one month of the year.
The growing scarcity of freshwater due to rising water demand, climate changes and pollution resulting from human activity is seen as a major risk for the global economy. Hence, minimisation of water use and reuse applications within industry has recently gained importance within the context of water conservation efforts.
The leather-tanning industry is one of the subject industries due to a large amount of water to be disposed of together with a high pollution load. The leather-tanning industry has a complex structure in terms of materials, processes and manufacturing practices. Therefore, a systematic approach is required to assess water-use practice.
