More than 116 mn tonne of waste clothes end up in the landfills every year. A sustainable manufacturer of functional fabrics, Singtex has developed Biotec series to tackle this issue. It reuses organic materials, such as coffee grounds, to make coffee oil membrane and castor beans to produce bio-nylon fabrics. These bio-based materials are said to replace more than 25 per cent petroleum consumption during production and offer a better wearing experience.
