Overall Winner

Project lead: Aida Rafat, Imperial College London UK

SDG 12: Reducing textile waste and reducing pollution from textile dyeing technologies.

This project is the result of research that solves two grand challenges in the textile industry: textile waste and polluting conventional dyeing technologies. This has been achieved by an innovative technology that enables the reuse and recycle of dyes from textile waste. The technology aims to divert the textile waste from landfill while also eliminating the use of virgin dyes derived from petrochemicals and instead uses textile waste as source of dyes. Decontaminated de-coloured textile fibres can also be recycled to produce new fibres via the fibre-to-fibre recycling technologies. The technology has potential to change the way fabrics are dyed and coloured in the future.
