Can we have a stylish pair of black jeans with a reduced footprint?
What we love:
- Black jeans with a stylish vintage and distressed look that can reflect our personal style
- Jeans that do not harm the planet
But did you know?
- Traditional black denim dyeing leads to big amounts of unwanted sulfides being released into the wastewater with complex treatment
- Multiple treatments are usually needed to create the vintage or distressed look which requires significant amounts of water and energy
- One of the treatments is potassium permanganate (PP) spraying which is very harmful for workers and the environment
