Il problema della scarsità dell’acqua sta emergendo ovunque nel mondo. Le risorse di acqua fresca si stanno esaurendo e l’efficienza nell’uso dell’acqua diventerà uno degli argomenti principali nei prossimi anni. Il settore tessile è uno dei maggiori utilizzatori d’acqua in Italia (e in Europa in generale), ma gli investimenti destinati a migliorare l’efficienza nell’uso dell’acqua o a migliorare i trattamenti delle acque reflue sono estremamente limitati. Questo lavoro si basa su uno stage di sei mesi presso l’azienda manifatturiera tessile Cotonificio Albini S.p.A. e differenti opzioni per migliorare la gestione dell’acqua all’interno dell’azienda sono state testate e valutate. I risultati dimostrano le possibilità nel migliorare l’efficienza nell’uso dell’acqua e ridurre l’impatto ambiente delle attività tessili. Gli effetti che ogni pratica per la corretta gestione dell’acqua ha sulle altre pratiche sono stati investigati, e i principali driver di costo individuati. Restano alte aree di interesse per successive analisi, anche considerando i possibili cambiamenti nelle tariffe sull’acquisto dell’acqua e sui servizi fognari e di trattamento dei reflui e i possibili cambiamenti alle leggi in materia ambientale.

Abstract
Water scarcity problem are arising everywhere in the world. Freshwater resources are being depleting and water efficiency will become a main topic in the next years. The textile sector is one of the major water consuming industrial sector in Italy (and in Europe in general), but the investment devoted to improving the water efficiency or the wastewater treatment are very limited. This work is based on a 6-months internship in the Italian textile manufacturer Cotonificio Albini S.p.A., and different options for improving the water management inside a textile company have been tested and evaluated. The results demonstrate that there are possibilities to improve the water efficiency and reduce the environmental impact of textile activities. The effects that any water management practice has on the other practices has been investigated, and the main cost drivers have been highlighted. There are other areas of interest for further investigation, also considering possible change that may happened in the next future in the water and wastewater treatment tariff, and in the regulatory framework.File | Dimensione | Formato | |
