Dr. Ajay I. Ranka: The Chemical-Free Cotton Man of India
August 01, 2026 | By Textile Sphere India
As the global textile industry intensifies its focus on sustainability, traceability, and responsible sourcing, the spotlight is increasingly shifting towards agricultural practices that form the foundation of the textile value chain. Dr. Ajay I. Ranka, Chairman & Managing Director of Zydex Group, has emerged as a leading advocate for chemical-free cotton cultivation through innovation-driven, science-based solutions. In this exclusive conversation with Textile Sphere India, he shares insights into Zydex’s sustainability journey, the growing importance of traceability, and the transformative impact of the Prakalp Sanjeevani Protocol. He also outlines his vision for positioning India as the world’s leading source of traceable, residue-free cotton, while empowering farmers with higher productivity, improved soil health, and enhanced profitability.
Q. Zydex has consistently led sustainable innovation. How has the company’s journey evolved over the years?
Dr. AR: Coming from a polymer science and chemical engineering background, I saw an opportunity to introduce meaningful innovation into textiles. Our early work replaced PVA and kerosene-based systems with cleaner alternatives. Since founding Zydex in 1997, sustainability has remained our guiding philosophy. Today we believe sustainability must extend across the entire textile lifecycle—from cotton cultivation to garment disposal—while protecting biodiversity, reducing pollution and conserving natural resources.
Q. What are the biggest sustainability challenges facing the textile industry today?
Dr. AR: The biggest challenge is responsible resource management. The industry must reduce dependence on finite resources, improve product durability, replace harmful materials with sustainable alternatives and move towards circularity. Zydex has focused on cleaner pigment printing technologies, advanced polymeric detergent systems and environmentally responsible chemistries that minimize water, air and land pollution without compromising performance.
Q. Why has traceability become so important in the cotton value chain?
Dr. AR: Traceability is becoming essential because brands and consumers increasingly want proof that cotton is genuinely sustainable. Authentic traceability begins at the farm and follows every stage—from cultivation, ginning and spinning to weaving, processing and garment manufacturing. Digital tools and QR-based systems can provide complete transparency and build confidence throughout the supply chain.
Q. How does Prakalp Sanjeevani help accelerate this transition?
Dr. AR: Prakalp Sanjeevani enables farmers to transition from conventional chemical farming to chemical-free cultivation within a single crop cycle. The protocol has demonstrated that farmers can maintain or improve yields while significantly reducing chemical inputs, improving profitability and producing cotton that meets global sustainability expectations.
Q. What benefits have participating farmers experienced?
Dr. AR: Field demonstrations across multiple regions have shown yield improvements of around 20%, substantial reductions in fertiliser and pesticide costs, healthier soils, stronger root systems and improved crop resilience. Since production costs decline while yields improve, farmer profitability increases without relying on premium pricing.
Q. What makes the Prakalp Sanjeevani Protocol scientifically different?
Dr. AR: The protocol integrates biological soil regeneration, bio-digestion, microbial technologies, polymer-enabled soil improvement, enhanced water retention and biological crop protection into one complete farming system. This improves soil biology, nutrient availability, root development, moisture management and overall plant health, enabling sustainable productivity.
Q. What is your long-term vision for India’s cotton industry?
Dr. AR: India possesses ideal natural conditions for producing sustainable cotton at scale. With the right technologies, farmer adoption and industry collaboration, India can become the global leader in traceable, residue-free cotton. My vision is for Kasturi Cotton to become synonymous worldwide with quality, sustainability and chemical-free cultivation.
Key Takeaways
- Sustainability must begin at the farm and continue across the textile value chain.
- Traceability is becoming a strategic requirement for global brands.
- Prakalp Sanjeevani enables chemical-free cotton without compromising yield.
- Farmers benefit through lower input costs, healthier soils and higher profitability.
- Biological technologies can restore soil fertility while supporting commercial-scale cotton production.
- India has the potential to become the world’s leading source of traceable sustainable cotton.
Conclusion
The future of sustainable textiles begins with sustainable agriculture. Through the Prakalp Sanjeevani Protocol, Zydex has demonstrated that chemical-free, traceable cotton production can be both environmentally responsible and commercially viable. By bringing together farmers, brands, textile manufacturers and policymakers, India has the opportunity to establish a globally recognized model for sustainable cotton production that benefits every stakeholder across the value chain.
