NTU Singapore and RGE Launch S$6 Million Joint Research Centre to Tackle Textile Waste

Driving high-impact research through interdisciplinary collaboration

The RGE-NTU SusTex leverages the University’s emphasis on interdisciplinary collaboration to catalyse high-impact research and take innovative ideas from the lab to the real world. It also builds on RGE’s wealth of industry experience and strong manufacturing capabilities. EDB seeded the relationship between NTU and RGE when the idea of an urban-fit textile recycling centre was first germinated last year.

The joint research centre will draw upon the expertise of NTU scientists in the School of Materials Science and Engineering and the School of Chemical and Biomedical Engineering.

It will look into four research areas:

• Cleaner and more energy efficient methods of recycling: looking at greener ways of textile recycling, with a focus on cellulose-based fabrics including rayon, viscose and cotton, minimising the degradation of fabric properties, and refabricating textile waste into fibre.
• Automated sorting of textile waste: using a combination of advanced spectroscopic techniques and machine learning capabilities for identifying and sorting textile waste based on fibre composition, and developing an automated system to remove accessories such as zips and buttons.
• Eco-friendly dye removal: developing eco-friendly methods of removing dye from textile waste using little to zero chlorinated chemicals, and formulating greener and biodegradable dye substitutes.
• New textiles: finding alternative uses for textile by-products and developing a new generation of eco-friendly and smart textiles with attributes such as moisture insensitivity, electrical conductivity, and infrared/ ultraviolet radiation reflectivity.

Leading the joint research centre in these research projects is Professor Hu Xiao from the NTU School of Materials Science and Engineering, who is also the director of the Environmental Chemistry & Materials Centre at NTU’s Nanyang Environment & Water Research Institute.

In conjunction with the establishment of the RGE-NTU SusTex, RGE plans to build a textile recycling pilot plant that is low carbon, low chemical emissions, and energy efficient in Singapore. The new sustainable textile recycling solutions developed under the RGE-NTU SusTex are expected to be test bedded in this pilot plant./NTUSingapore
