As part of the CLEANTEX project: A Clean and Innovative Strategy for the Circular Economy in Textiles, the CLEANTEX e-book was published with practical examples of implementing circular economy and eco-design in textile companies. The e-book provides information on life cycle analysis (LCA) methodology, eco-design implementation phases and eighteen examples of companies from Slovenia, Lithuania, France, Italy, Spain, and Greece that have already introduced sustainable approaches, models, and measures in their production processes.
