Dying is one of the most environmentally destructive parts of textile production, sending hormone-disrupting chemicals into waterways in big textile-producing countries like China, India and Bangladesh. But what if tainted effluent from textile production could be purified, leaving nothing more than water for factories to discharge? That’s exactly the problem that Maria Jonstrup, a doctoral student in Biotechnology at Lund University in Sweden, has been working on, and she recently made a breakthrough that could prevent harmful chemicals from entering the environment. So far Jonstrup’s technique has only been tested in the lab, but she plans to test it at a factory in India.
