M. Thadhani, Senior Research Scientist SLINTEC; Gerard Irudayaraj, Director Supply Chain - Unilever Sri Lanka and Anusha Kotalawala, Factory Manager, Unilever Ceytea Instant Tea Factory, Sri Lanka.
This partnership was launched during the recent Shilpa Sena exposition organized by the Ministry of Science, Technology and Research at the BMICH, Colombo,
This initiative falls under the Unilever Sustainable Living Plan, a proprietary project with the goal of decoupling the company’s growth from environmental impact, while increasing its positive social impact. The plan has three big goals that by 2020 will help improve people’s health and well-being, reduce the company’s environmental footprint, and enhance livelihoods across its value chain, according to a media release from Unilever.
This convergence of purpose to reduce organisational carbon footprints resulted in the partnership of Unilever, SLINTEC and Dynawash to explore the creation of natural dyes using a by-product which is generated during Unilever Sri Lanka’s instant tea manufacturing process. Over 40 metric tons of Broken Mixed Fannings (BMF), is used every day as a raw material at Unilever’s Ceytea instant tea plant located in Agarapathana. The BMF is first filtered, waste segregated post extracting the soluble, evaporated, and subsequently spray dried to obtain the base ingredient to produce tea dye in powder form. This tea dye is then transformed into colour palettes as per customer requirements.
In view of this revolutionary initiative, Anusha Kotalawala, Factory Manager, Unilever Ceytea Instant Tea Factory, Sri Lanka said:, “I am sure that this technologically advanced method to upcycle our waste product for use as a dye will be a stepping stone for all manufacturers to reconsider their carbon emissions in order to work in a more sustainable manner. It gives us great pleasure to know that by participating in this initiative, the carbon footprint of both our industries can be significantly reduced.”
Principal investigator of the invention, Prof. V. M. Thadhani, Senior Research Scientist,SLINTEC, voicing her thoughts said, “The concept of utilising waste material from Unilever’s instant tea manufacturing process as a raw material for apparel dyeing will be a sustainable alternative to the chemical dyeing used for garments. Work on the project commenced in 2016 with Prof. Gehan Amaratunga of the University of Cambridge, UK and the intellectual property of the invention is owned by SLINTEC. We are pleased to see responsible organisations such as Unilever and Dynawash leading this agenda.”
Shahid Sangani, CEO Dynawash had this to say, “We are very proud to contribute towards this effort through our collaboration with Unilever Sri Lanka and SLINTEC in developing a Sustainable Natural Dye from Tea Waste – T Hues. In the conventional form, fabric dyeing through the use of synthetic dyes results in a total greenhouse gas emission as high as 2287g and 1855g respectively for Acid Dying and Reactive Dying per Kg of Garment. Switching to T Hues, has reduced the CO2 equivalent by 34 per cent and 76 per cent respectively.”
