RALEIGH – Academics at North Carolina State University (NC State) claim to have developed a synthetic polymer capable of removing dyes – used in the production of textiles, leather and cosmetics – from wastewater.

A polycarbodiimide, the polymer is said to be reusable and has proven in trials its effectiveness against several acid dyes.

“Dyes are used everywhere, including in the textile industry, as well as in pharmaceuticals, cosmetics, paper, leather and even in medicines,” said Januka Budhathoki-Uprety, an assistant professor of textile engineering, chemistry and science at NC State. “If these contaminants aren’t properly removed from wastewater after dyeing and finishing, they can be a significant source of environmental pollution and pose risks for human health.”
