TRASH2TREASURE has launched an innovative pilot project for the upcycling of unused packaging materials with the Japanese company Kao. With Kao as the first external industrial partner, TRASH2TREASURE has made storage boxes for the solid shampoos of the hair care brand Guhl from unused PET bottles. When buying one of the two products, Guhl Solid Shampoo Volume or Nature Repair, the customer receives a free box. Available e.g. at Rossmann.
