Why is JB Ecotex’s Green Mindset and Zero Liquid Discharge Commitment Beyond Profit? — 2025 Update

The textile industry dazzles with colour and creativity, but its dependence on water has long placed a strain on natural ecosystems. Large volumes are withdrawn for dyeing, finishing, and processing, while untreated effluents often end up in rivers. With freshwater scarcity now a global reality, the sector faces a question that cannot be avoided: how can it grow without exhausting the very resources it relies on?

JB Ecotex Ltd, based in Surat, has placed sustainability at the centre of its identity. By investing in the zero liquid discharge plant, scaling rPET recycling, adopting renewable energy, and facilitating the EPR systems, the company is proving that manufacturing can align with ecological stewardship.

What Does Zero Liquid Discharge Mean in the Textile Industry?

Zero Liquid Discharge (ZLD) refers to a system where all wastewater is treated, recovered, and reused within industrial operations. No untreated effluent is released into the environment. For the textile industry, ZLD is vital because textile dyeing and processing are among the most water-intensive activities in manufacturing.

Globally, ZLD adoption is growing. India has emerged as one of the leading regions implementing this technology, particularly in Gujarat and Tamil Nadu, where state pollution boards encourage ZLD to protect scarce water resources. For exporters, ZLD also supports compliance with international buyers’ sustainability requirements.

Government Regulations Driving the Zero Liquid Discharge Textile Industry

In India, the Central Pollution Control Board (CPCB) and state-level agencies such as the Gujarat Pollution Control Board (GPCB) have set clear mandates for wastewater treatment. ZLD systems help companies comply with these norms by ensuring zero discharge of liquid waste.

For textile exporters, ZLD is also becoming a business necessity. Global buyers increasingly require supply chains to demonstrate compliance with environmental standards. By aligning with CPCB and international certifications, companies in the Indian textile industry are able to meet domestic regulations while maintaining competitiveness in global markets.

Technologies Behind ZLD in Textile Manufacturing

JB Ecotex operates a Zero Liquid Discharge Plant designed for efficiency and compliance. The system combines several advanced technologies:

• Reverse Osmosis (RO): Removes salts, dyes, and dissolved solids.
• Multiple-Effect Evaporators (MEE): Concentrates remaining effluents by reusing thermal energy.
• Crystallisers: Converts concentrated salts into solid waste for safe disposal.
• Closed-Loop System: Purified water re-enters the manufacturing process, reducing freshwater withdrawals.

This multi-stage approach demonstrates how technology supports both compliance and conservation in sustainable textile manufacturing.

Cost Savings from Water Reuse and Energy Recovery

Zero Liquid Discharge is often seen as an environmental obligation, but it also delivers measurable business benefits.

Benefits of ZLD at JB Ecotex:

• Lower freshwater intake costs through reuse of treated water.
• Reduced energy bills by reusing heat from evaporators.
• Lower waste handling expenses, as crystallised solids are safer and cheaper to manage.
• Reliable water availability even in times of scarcity, reducing downtime risks.

These benefits show that the zero liquid discharge creates resilience both for businesses and for natural resources.

Renewable Energy in the Textile Industry 

Energy is another critical dimension of sustainability. JB Ecotex has invested significantly in clean energy, adopting solar energy in industries in India and expanding the share of renewables in its operation

• Solar Energy Capacity: 8.6 MW across three installations (1.2 MW operational, 2.0 MW upcoming, 5.4 MW upcoming in Jetda, Gujarat).
• Wind Energy Capacity: 7.2 MW from three windmills in Gujarat (2.1 MW at Khiri, 2.1 MW at Gondal, 3.0 MW at Gondal).
• Total Renewable Energy Portfolio: 15.8 MW from combined solar and wind assets.

This integration not only reduces greenhouse gases but also ensures predictable energy costs. For the renewable energy in textile industry shift, JB Ecotex serves as a practical example of how large industrial operations can integrate clean energy at scale.

Closing the Loop: Recycling PET Bottles into rPET

JB Ecotex has been operating as a recycler of post-consumer PET bottles in India for over a decade. Every year, billions of bottles risk becoming landfill waste or ocean-bound plastic, but JB Ecotex reprocesses these bottles into high-value products:

• Recycled Polyester Staple Fibre (RPSF)
• B2B rPET resins for packaging and textiles
• Food-grade flakes for closed-loop system packaging

This system supports rPET recycling in India at scale while enabling the circular economy in textiles. Through recycling, JB Ecotex reduces reliance on virgin plastic and provides sustainable materials for global brands.

Water Conservation in Textile Manufacturing

Water is central to textile production, yet also one of the most threatened resources. JB Ecotex integrates multiple initiatives for water conservation in textiles:

• Effluent Treatment Capacity: Complete utilization through ZLD.
• Rainwater Harvesting Systems for seasonal water capture.
• Closed-Loop Systems where every litre treated re-enters production.

These initiatives reduce reliance on external freshwater, protect local rivers, and ensure resource resilience for industrial operations.

Global Adoption of Zero Liquid Discharge

The zero liquid discharge textile industry is gaining momentum worldwide. Countries like China, Italy, and India are advancing adoption, with governments mandating ZLD in high-polluting sectors like textile industry. Export-driven regions in India, including Surat, are aligning with these trends to maintain market access.

Global buyers, especially in fashion and packaging, increasingly prefer suppliers with ZLD systems because they ensure compliance with sustainability standards. This makes ZLD not just a compliance tool but also a competitive advantage in the global textile supply chain.
