SEDO ENGINEERING SA

SMART INDIGO™ is the brand of Sedo Engineering SA, Switzerland, offering a revolutionary and sustainable technology for indigo and denim dyeing. The SMART INDIGO™ solution is based on a patented electrochemical process that produces liquid leuco‑indigo using electricity instead of hazardous chemicals. The process uses only indigo pigment, caustic soda, water, and electricity, with oxygen as the only by‑product. SMART INDIGO™ enables on‑site, fully automated production of clean leuco‑indigo, significantly reducing CO₂ emissions, energy and water consumption while improving workplace safety and dyeing consistency. By eliminating hydrosulphite‑based reduction, the technology simplifies wastewater treatment and supports more ecological and economical denim production. The SMART INDIGO™ technology is industrially proven and successfully applied in the denim industry worldwide. It supports stable, repeatable dyeing results and helps manufacturers reduce their environmental footprint while meeting growing sustainability and regulatory requirements. With Swiss engineering quality and a strong focus on automation and reliability, SMART INDIGO™ represents a decisive step toward cleaner, safer, and future‑ready indigo dyeing.
