As a student assistant at the Group for Sustainable Production and Logistics Management I deal with production-theoretical basics that are oriented towards real problems. Among other things, I help prepare lectures on production, logistics and sustainability management. This includes topics such as global supply and value chains, fair trade, and business ethics. The group also deals with issues related to the circular economy. As a solution to resource scarcity and climate change, the life cycle of products should be made more sustainable and not end with disposal. It is therefore important to consider recycling options as early as the development stage, so that materials can be used again in manufacturing processes after reprocessing. For me as a budding engineer, this is the future. Later in my professional life, I would like to help optimize the use of finite resources. In my master's thesis, I will investigate the method of life cycle assessment in connection with circular economy aspects. In my private life, sustainability is also very important to me: I cover the vast majority of my journeys by bike or train, avoid air travel, use appliances until the end of their lives and buy some second-hand clothing.
