Rajby Textiles Pvt. Ltd. has opened a garment manufacturing unit in Karachi with an initial capacity of 500,000 pieces per month, the company announced on Wednesday. Management plans to double output to 1 million pieces per month in a second phase.

The new unit anchors a vertical integration play. Rajby's existing fabric division, which produces 3.2 million meters of denim per month, will supply the garment plant directly, moving the Karachi-based company from fabric mill to end-to-end denim supplier for global apparel brands. Rajby is a confirmed C&A supplier.

The facility runs auto spreaders, pocket setters, automatic hemmers and loop attachers to hold tolerances and cut lead times on volume denim production. On the finishing side, Rajby has installed Jeanologia ozone technology, laser finishing and high-efficiency industrial washers — equipment choices that determine chemical load and water consumption per garment as much as throughput.

"For over 50 years, Rajby Textiles has built its reputation on manufacturing excellence, quality, and continuous innovation," said Daniyal Saleem, CEO at Rajby Textiles. "With this new garment facility, we are bringing that same commitment to the finished product. By combining modern automation with sustainable technologies, we are offering our global brand partners an integrated, responsible, and agile supply chain."

Compliance targets traceable to ZDHC

Rajby framed its sustainability commitments as measurable targets for the apparel division, covering water, energy and waste. On wastewater, the company is upgrading its effluent treatment plant with an MBBR biological and tertiary treatment process to reach ZDHC Progressive level — the second tier of the ZDHC Roadmap to Zero wastewater discharge standard that major denim buyers increasingly write into supplier codes.

The division will install a wastewater recycling plant targeting 30 percent recycling by 2027, which Rajby says saves water equivalent to the daily usage of 17,280 people, and 100 percent recycling by 2030.

On energy, an 800-KWh solar plant at the garment unit will cut local emissions by 25 percent, and the apparel division aims to halve greenhouse gas emissions by 2030. The unit will operate under a reduce-reuse-recycle methodology with a target of zero manufacturing waste to landfill by 2030.

These commitments extend existing infrastructure at the fabric unit, which already runs biomass boilers, waste heat recovery systems supplying 95 percent renewable steam generation, and solar power. The company said the new targets "build upon existing energy-saving milestones" at the fabric division.

What it means for sourcing desks

The investment tracks a wider structural shift in denim sourcing: brands consolidating volumes with vertically integrated mills that can control fabric, cut-make-trim and finishing compliance under one roof. For buyers weighing Pakistan capacity against Bangladesh and China, Rajby's Karachi unit adds finished-garment capability backed by a fabric base that already moves 3.2 million meters monthly, with compliance claims tied to a named standard rather than general pledges.

The decision the news forces is verification. Sourcing teams evaluating the facility should require ZDHC Progressive-level wastewater data through the ZDHC Gateway, confirm the 2027 and 2030 recycling and emissions targets in supplier agreements, and audit the 25 percent emissions reduction claim against the solar plant's actual generation — separating confirmed capability from stated ambition before committing volume.
