Water & Effluent
Water is a critical resource for Archroma during chemical manufacture. It is primarily used as a processing
aid in cooling, cleaning and air scrubbing/washing, and as a raw material in the production of commercial
liquid based formulations, such as liquid dyes and polymeric dispersions and is also evaporated during
spray drying in the production of dry formulations.
Archroma withdrew a total of 8.83 million m3 of water in FY2018, which represents a 26% increase
compared to the reported figure for FY2017 (7.00 million m3), however this figure was under-reported,
as cooling water in one of our sites had been omitted from the total (1 068 347 m3). Taking this into
consideration our FY2018 withdrawal represents a 9.3% increase over the previous reporting period.
Of the total withdrawn 49% is sourced from surface water and 29% from groundwater. The remaining
23% being supplied from third parties (such as corporation water supply, industry site services).
10 of our production sites are located in water stress areas

Baseline water stress measures the ratio
of total water withdrawals to available
renewable surface and ground water
supplies. Water withdrawals include domestic,
industrial, irrigation, and livestock consumptive
and non-consumptive uses. Available
renewable water supplies include the impact
of upstream consumptive water users and
large dams on downstream water availability.
Higher values indicate more competition
among users.
In these sites Archroma withdrew 1.33 million m3 of water in FY2018. Only 5% of the water withdrawn in
these areas was sourced from groundwater, 57% from surface water. The remaining 38% was supplied
by third party water suppliers, and of this 97% originated from surface water. Thus we are minimizing any
effect on the aquifer in water stressed areas. In order to reduce the depletion of this valuable resource
in these areas, our target will be to reduce water withdrawal in these sites by 40% to a total 798 000 m3
withdrawn in 2023.

One of these sites is our site in Jamshoro, Pakistan. As we have
employed water recycling to reuse 70% of the required water for the
plant, as a part of the “Sustainable Effluent Treatment” system
established in 2012, we only withdraw 737 264 m3 from the Indus
River in the reporting period. As a product raw material, and to allow
for evaporation loss, we consumed 362 572 m3, the remaining water,
374 692 m3, was supplied to the local community for drinking water.

Water consumption in FY2018, which is water used, for example, as a raw material, to generate steam or
lost through evaporation, amounted to 2.09 million m3 which represents 24% of the total water withdrawn.
In the water stressed areas water consumption increases to 39% of water withdrawn, which is indicative of
the water recycling initiatives used in these production sites.
