Sustainability is much more than just keeping our environment clean. Sustainability is a holistic lifestyle concept embracing values, attitude towards people and nature, and is relevant to all kinds of goods which are subject to a life cycle process. Sustainability is at the core of Kleiderkreisel GmbH based in Berlin. Its online marketplace for second-hand fashion has become a must not only for environmentally aware fashionistas, but also five million young women in Germany. CEO Justas Janauskas is convinced he can transfer this concept to new markets in the coming years.
