How does IOAN handle waste water from its natural dying processes?

Indigo dye

After the harvest of the indigo plant, water is needed to extract the indigo pigment from Indigofera Tinctoria. This water is returned to farmlands for irrigation as it contains no toxic elements. The garment dying process also yields zero water discharge as garments are dyed in fermented indigo vats, in which dyeing solution is kept for many years maintained with lime and other natural elements.

Other natural dyes

Any sediment left from the dye is composted and applied around the base of other plants, with remaining water used for the irrigation of coconuts, cashews and bananas.
