Swiss textile machinery supplier Sedo Engineering uses electricity instead of chemicals to produce pre-reduced indigo dyestuffs for denim.

Sedo’s direct electrochemical process reduces indigo pigment to its soluble state without the need for hazardous chemicals such as sodium hydrosulphite and is said to save natural resources in the process.

General manager of Sedo said “We’ve had several new orders from denim mills in Pakistan, including Kassim and Soorty, where two more will follow – we’re also growing our capacity to make more machines to service demand”
