Textile startup Aizome isn't playing when it says that "even our waste is good for you". To prove just how clean its state-of-the-art ultrasonic dyeing method is, Aizome has created the world's first skincare product made from industrial waste. Bottling up its own factory wastewater, the medicinal night serum – dubbed Wastecare – has not only passed rigorous cosmetic safety standards with flying colours, but it offers a range of health benefits too, thanks to indigo's impressive healing qualities. Although Wastecare is not a consumer product (yet), Aizome's thought-provoking concept is radically redefining waste.
