Sustainability Rantex (Pvt.) Ltd.
Responsible from fiber to fabric.
From Direct-to-Farm cotton and regenerative agriculture to biological effluent treatment and solar energy, responsibility runs through every stage of how Rantex makes denim.

01 Traceability
From farm
to fabric.
Transparency is no longer an option in the denim supply chain. It is becoming a prerequisite.
Rantex has developed an end-to-end mapped supply chain, providing visibility across the sourcing and manufacturing journey. Our Direct-to-Farm cotton programs enable greater traceability back to the fiber origin and create a stronger foundation for responsible sourcing and sustainability reporting.
Combined with our capabilities in responsible cotton sourcing and regenerative agriculture initiatives, we help brands move beyond generic sustainability claims toward a more transparent and traceable material story.
- End-to-end mapped supply chain
- Direct-to-Farm cotton programs
- Responsible cotton sourcing
- Regenerative agriculture initiatives
02 Sustainable fibers
Responsible
fiber sourcing.
A fabric's footprint is largely determined by its fiber. Our sourcing programs prioritize responsible and traceable materials.
-
Better Cotton
More efficient water use, improved soil and habitat care, and better conditions for farmers.
-
Organic cotton
Grown without toxic or persistent pesticides and fertilizers, and traceable from the field.
-
Recycled cotton
Reduces virgin cotton, water, land and chemical use, and diverts solid waste from landfill.
-
Wood-based fiber
Sourced from sustainably managed forests, with solvent and water recovered in a closed loop.
03 Water treatment plant
Biological effluent
treatment.
Our SIMEM biological effluent treatment plant treats wastewater to regulated pH, BOD and COD limits, and all indigo waste is processed before controlled discharge.

04 Solar energy
Renewable energy
initiatives.
Rooftop solar generation supplies the looms and finishing lines during daylight hours, reducing our reliance on grid electricity.
- 2.4 MW
- Installed capacity
- 3,600
- MWh generated a year
- 5,800
- Panels on the roof
38% of the mill's electricity comes from the sun
05 Carbon footprint
Measured and reduced
year on year.
We measure the carbon behind every meter of denim, covering fuel and purchased electricity, and set a lower target each year.
- Energy audits across spinning preparation, dyeing, weaving and finishing
- Heat recovered from finishing and reused in the dye house
- Solar power replacing grid electricity in daylight hours
06 Recycled
Responsible waste
management.
Cotton waste is reclaimed into recycled yarn. All other waste is segregated at source and managed in a fixed order: avoid, reduce, treat, dispose.
- 01
Collect
Yarn waste, selvedge trim and fabric remnants are gathered at each machine.
- 02
Sort
Hazardous and non-hazardous streams are kept apart, along with packaging and paper.
- 03
Reclaim
Cotton waste is opened back into fiber and blended into recycled yarn.
- 04
Reweave
Recycled yarn returns to the loom as denim made to the Global Recycled Standard.
- 92%
- Of solid waste recycled or reused
- 1,150 t
- Of cotton waste reclaimed a year
- Quarterly
- Air emission monitoring at every source
- Zero
- Waste to landfill is the long-term goal
