Smart-Indigo™: High sustainability; Reduced health hazards; Savings in wastewater treatment and energy; Better colour consistency and performance; More ecological and economical; Easy to handle and more efficient
During one year over 15 billion meters of denim fabric are produced. Most of the production takes place in countries like China (52%), India & Pakistan (15%), Mexico & Brazil (13%), Europe & Turkey & Middle East (7%), USA & Canada (4%), rest of the world (9%).
The demand for denim continues to grow, with each of us already owning four or more denim fashion items. 66’000 tons of indigo powder is needed to produce 15 billion meters of denim fabrics to different shades of blue. The famous blue indigo is a powder which needs hazardous chemicals to make it water soluble for the dyeing process.
After dyeing, tons of wastewater containing these chemicals is discharged into the environment often without treatment. The excessive damages caused by those chemicals and heavy metals, like cadmium, chromium, mercury, lead, and copper are harmful to humans, animals and the environment.
Furthermore chemicals left on the denim fabrics after industrial washing can still effect our skin. Imagine wearing denims which are contaminated with chemicals! The denim dyeing process is one of the major pollution problems within the textile industry.
Time for a change.
SmartIndigo™ will resolve these issues. This Swiss invention which utilises a 100yearold discovery (A. Brochet, 1917) becomes reality. Tons of leucoindigo can be produced without chemicals.
Smart-Indigo™: Because It Makes A Difference
“Smart LeucoIndigo” is produced in an electrochemical process consuming considerably fewer resources than existing methods. Using only indigo pigment, caustic soda, water and electricity. This technology is the most environmentally friendly process to dye denim. SmartIndigo™ is a global innovation and will markedly reduce the ecological footprint.
Behind this technology are experienced specialists in the dyeing and finishing industry. Located in Switzerland, represented globally, with established and innovative products selling all over the world. Time to market for this development, replacing chemicals with electricity was 5 years in the making. Two years longer than originally planned “-Nothing good comes easy- kept us awake more than once through desperate nights.” Mr. Herbert Guebeli, managing director says. This resulting clean technology now speaks for itself. It makes a difference.
Smart-Indigo™
Smart-Indigo™ stands for an industrially proven technology, which will make a difference by bringing a revolutionary change to the global denim dyeing industry. Combining benefits for the environment, the people and the producers of denim items.

Around the world a growing movement of people are using their creativity, design skills and purchasing power to demand fashion without pollution. United by a shared belief that the clothes we wear should carry a story we can be proud of, activists, bloggers, designers, scientists and models have been able to convince big brands including Zara, Mango, Valentino, UNIQLO and H&M to commit to toxic-free fashion. There is still a long way to go, but our successes so far prove that when we work together, big brands are forced to stand up and deliver.
