Syluxia, Latin for « fusion and light », mimics an optical phenomenon observed on living species to create colors. This process uses a renewable resource (cellulose) which is combined to nanotechnology to create a flexible colored bio-film that is compatible with many materials. We aim to source wasted cellulosic fibers from the textile or food industry. Besides fashion, industries as automotive/aerospace and architecture might benefit from it. Reducing our reliance on petroleum-based dye processes to decrease chemical pollution in water, air and soil from the dyeing industry is our challenge.
