Sustainability

Manufacturing With a Lighter Footprint

A 500kW solar installation and an in-house effluent treatment plant are part of how we run our Karachi facility — reducing reliance on grid power and treating process water before it leaves our site.

Solar Power

500kW Installed Capacity

Panels are mounted directly on the factory roof, supplying a share of the electricity our weaving, dyeing and finishing floors run on day to day.

The CO₂ figure is a modeled estimate — 500kW capacity at a typical regional solar yield, offset against Pakistan's average grid emission factor — not a metered reading.

Why It Matters

Solar Power in Textile Manufacturing

Terry towel production is energy-intensive — weaving looms, dyeing machines, dryers and finishing lines all draw significant power through the day. Solar generation offsets a portion of that load directly at the source.

  • Lower reliance on grid electricity and diesel backup generation, which is common across Pakistani industrial zones during periods of load-shedding
  • A cleaner energy mix behind every towel we ship, without changing product quality, construction or handfeel
  • More stable production scheduling — daytime manufacturing floors run on generation that isn't fully dependent on grid supply
  • A concrete, verifiable sustainability data point for buyers with ESG or scope 2 emissions reporting requirements in their own supply chain
Water & Effluent

Effluent Treatment Plant

Dyeing and wet processing generate wastewater — our in-house treatment plant processes it on site before discharge, rather than relying on external or municipal handling.

01 · Collection

Process wastewater from dyeing and wet finishing is collected separately from general site drainage.

02 · Treatment

Physico-chemical treatment — screening, equalization, coagulation-flocculation and sedimentation — the standard process for textile dyeing effluent.

03 · Testing

Treated water is tested against Pakistan's National Environmental Quality Standards (NEQS) for industrial liquid effluent.

04 · Discharge

Released only once it meets NEQS limits for pH, BOD, COD, TSS and other regulated parameters.

Beyond Energy & Water

Other Practices in Place

01

Azo-Free Dyes

All dyestuffs and chemicals used in our dyeing process are azo-free, in line with international restricted-substance standards.

02

OEKO-TEX Class I

Our Standard 100 certification covers the strictest class of testing, applied to products made for babies and small children.

03

Vertical Integration

Weaving, dyeing and finishing under one roof means shorter transport distances between production stages compared to outsourced, multi-site supply chains.
