Smart-Indigo™ was launched in Bangladesh in a grand seminar ‘Sustainable Denim Days’ on 23 February at a hotel in Dhaka. At the seminar S. M. Al Masud, Founder and MD of SM Engineering Ltd. (exclusive agents of Sedo Engineering) introduced the new technology and shared his journey with Sedo Engineering.
Herbert Guebeli, Managing Director, Smart-Indigo™, elaborated on the Smart-Indigo™ technology. Distinguished guests, Bangladesh denim sector leaders, VC’s of renowned textile universities were present at the seminar.
On the second day (24 February) of the event leading denim manufacturers, brands visited the Smart-Indigo™ technology at SM Engineering Smart Indigo plant at Mawna, Gazipur. In the plant visit event leading denim manufacturers like Mahmud Denim, Amber Denim, Partex Denim, Ha-Meem Group, Esquire Denim, etc. denim experts, leading brands, different associations were present. Also renowned textile university Vice-Chancellors like Prof MA Kashem, Vice-Chancellor, BUTEX; Prof S. M. Mahfuzur Rahman, Vice-Chancellor, BUFT; Prof. Dr. Muhammad Fazli Ilahi, Vice-Chancellor, Ahsanullah University of Science & Technology; Prof. Dr. Anwar Hossain, Vice-Chancellor, Northern University; Dr. Md. Abdus Shahid, Head, Department of Textile Engineering, DUET. Government officials, Deputy Directors, Ministry of Textiles officials, and journalists were present at the event.
Why does textile industry need Smart-Indigo™?
The demand for denim continues to grow. Yearly over 15 billion meters of denim fabric are produced with 66’000 tons of indigo powder to create different shades of blue. The famous blue indigo is a powder that 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.
SmartIndigo™ by Sedo Engineering SA will resolve these issues. This Swiss invention which utilizes a 100yearold discovery (A. Brochet, 1917). Indigo can be produced with electricity instead of chemicals.
‘Smart Indigo’ is produced in an electrochemical process consuming considerably fewer resources than the existing method 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, said Herbert Guebeli.
“Nothing good comes easy- kept us awake more than once through desperate nights. This resulting clean technology now speaks for itself and it makes a difference,” said Herbert Guebeli.
The smarter way to indigo
Smart-Indigo™ revolutionizes the dyeing process for denim. It opens up the industrial production of Leuco-Indigo on the basis of electrochemical reduction for the first time. This environmentally friendly process was evolved in Switzerland and developed technologically to marketability. Global innovation! The smarter way to indigo is trend-setting for the whole denim industry.
Smart-Indigo™ production on-site
‘Smart-Indigo™’ is produced by electrochemical processes consuming considerably fewer resources than existing methods. Using only indigo pigment, caustic soda, water and electricity.
In a fully automated process, the clean Leuco-Indigo is produced, metered and fed directly to the dye bath. The Smart-Indigo™ solution is the most sustainable way to dye denim.
The profitable way to indigo
Smart Indigo™ makes more from less. Using only indigo pigment, caustic soda (NaOH), water and electricity ‘Smart-Indigo™’ is produced in an electrochemical process requiring considerably fewer resources than previous process methods. In a fully automated process, the clean Leuco-Indigo is produced, metered and fed directly to the dye baths.
“The Smart-Indigo™ solution reduces wastewater treatment and transport costs and also contributes to efficiency and profitability,” Herbert Guebeli mentioned.
The easier way to indigo
Smart-Indigo™ Clean technology ‘Cleantech’ increases the competitiveness of dyeing factories and benefits health and environment. Sedo Engineering manufactures the technical equipment for the electrochemical reduction process. They stand for first-class Swiss quality offering possibilities for fully automated systems.
Herbert Guebeli highlighted that the modular system design allows easy servicing. Smart-Indigo™ fundamentally simplifies processes. An investment in Smart-Indigo™ is an investment in a sustainable and economically successful future for dyeing companies to the benefits of all.
