Use this story and the summary slide to help 14–16 learners better understand using the Earth’s resources with this real-world context. A new enzymatic process promises a greener approach to denim dyeing, eliminating harsh chemicals while maintaining the blue hue. Researchers in Denmark use enzymes to produce indican, a natural precursor of indigo. Life cycle assessments confirm its minimal environmental impact and compatibility with existing dye factory set-ups, marking a significant step towards sustainable denim manufacturing.
