Shree Renga Polyester Advances Sustainable Textiles With PLA Yarn Development

Shree Renga Polyester has successfully completed research and development work on Polylactic Acid (PLA)-based yarns, marking a significant milestone in its sustainability journey. The project was undertaken in collaboration with the South India Textile Research Association (SITRA) and received support from the Government of Tamil Nadu through a research grant.

PLA is a bio-based and compostable fibre derived from renewable resources, offering a viable alternative to conventional petroleum-based synthetic fibres. The successful development and laboratory-scale trials of PLA yarns at Shree Renga Polyester’s facility highlight the growing momentum within the Indian textile industry toward sustainable and environmentally responsible material innovation.

The company stated that the project represents an important step toward reducing dependence on fossil fuel-derived fibres while supporting the transition to circular and low-impact textile solutions. The achievement is the result of close collaboration between industry, research institutions and government agencies, demonstrating the value of a collective approach to textile innovation.

With sustainability becoming a key focus area across global textile supply chains, PLA fibres are increasingly being explored for their potential applications in apparel, home textiles and technical textile segments. Their renewable origin and compostability make them an attractive option for brands seeking to lower their environmental footprint.

Building on the success of the project, Shree Renga Polyester has expressed its willingness to collaborate with universities, research institutions and industry partners interested in advancing sustainable fibre technologies. The company aims to leverage its R&D infrastructure to support further experimentation and innovation in next-generation textile materials.
