Materials Recycling - Growth, Ressources, Environment and Materials Recycling


(apl. Prof. Dr.-Ing. Jan Frenzel)

The standard of living in our world is based on a number of key parameters. We must be able to produce goods of high technical standards. These goods must fulfill a number of requirements. They must be useful and have a pleasant aesthetic appearance. During their whole life cycle, they should be energy efficient and environmentally friendly. It should be possible to manufacture them at competitive prices. Modern materials technology should aim at a minimum consumption of a material for each technical benefit, in an environment of ever increasing overall complexity. Technical systems (like power plants or cars) combine different materials and hence their environmental impact and their exploitable service lives are associated with the life cycles of different materials. When a system reaches the end of its service life, one has to dispose of the materials from which its components are made. This lecture considers and discusses the two extremes presently applied by mankind. In the best case scenario, secondary raw materials can be recycled from waste (secondary materials) or materials can be used for energy production. The use of recycled materials contributes to a sustainable technology development. In contrast, the worst case scenario consists of a final state, in which, after service, the atoms of a material are finely distributed (in the earth, the atmosphere or the oceans).

The class takes place in the winter semester on Fridays from 4:00 to 7:00 p.m.
