Bisleri International has entered into a strategic partnership with EcoLine Clothing, the sustainable fashion brand of Shree Renga Polyester Pvt Ltd, to repurpose used PET bottles collected through its flagship Bottles For Change initiative. These bottles will be transformed into premium fashion and lifestyle products under the EcoLine label, promoting circularity and reducing plastic waste.

The MoU was signed by Angelo George, CEO of Bisleri International, and K Sankar, Chairman of Shree Renga Polyester, in the presence of K Ganesh, Head of Sustainability and CSR at Bisleri International, and Senthil Sankar, Managing Director of Shree Renga Polyester and Co-founder of EcoLine Clothing, says a release.

Through this partnership, collected PET bottles will be transformed into finished products such as jackets, uniforms, bags and apparel using EcoLine’s bottle-to-fabric technology, which incorporates dope dyeing and nanotechnology for enhanced durability and sustainability. This model has already proven successful in previous collaborations with the Indian Army (Siachen) and the Royal Government of Bhutan, the release said.

Angelo George, CEO, Bisleri International, said, “Our partnership with Shree Renga Polyester through its EcoLine brand is a significant step forward in extending the life cycle of used plastic. Together, we are not just recycling PET bottles—we are reimagining their potential by transforming them into sustainable fashion and lifestyle solutions.”

K Sankar, Founder & Chairman, Shree Renga Polyester Pvt Ltd, said, “This collaboration is an example of how two mission-driven organisations can create environmental and social impact at scale. At EcoLine, we believe sustainability must be visible, wearable and affordable. With Bisleri’s nationwide collection network and our vertical integration, we’re excited to close the loop on plastic waste.”

Senthil Sankar of Ecoline told businessline that every day 2 million bottles are being recycled at the company’s plant in Karur. “We make close to 30 tonnes of polyester with that per day or 10,800 tonnes of polyester per year. We can make one t-shirt from around 6 bottles (1 litre). Most of the fabrics are 100 per cent polyester. For some products, we add organic cotton, tencel and bamboo. We ensure the raw material we use is sustainable,” he added.

EcoLine converts used PET bottles into yarn and fabric through a clean, closed-loop process. The bottles are crushed into flakes, melted into chips, and then spun into yarn. This yarn is then knitted or woven into fabric. The company sources the pet bottles from Tamil Nadu, Pondicherry and Kerala, he added.

Bisleri is planning to work with the Kerala government and collect the bottles through women self-help groups and supply them to the company, he said.
