Materials Recycling - Growth, Ressources, Environment and Materials Recycling

(Dr.-Ing. Jan Frenzel, Prof. Dr.-Ing. Gunther Eggeler)

In the world in which we live, prosperity can only be assured if we are able to produce goods which are of high technical standards, of use to mankind, aesthetically pleasing and energy efficient; furthermore, they need to be environmentally friendly and should be manufacturable at competitive prices. Modern technology is characterised by the consumption of a minimum of materials per technical benefit in a climate of increasing complexity. The cycles of various materials converge to make up a technical system and remain together during the life of that system. This series of lectures considers the two extremes with which the operator is confronted once a system reaches the end of its useful service life. In the best case scenario, secondary raw materials can be recycled from waste. This can be achieved by reusing materials as new ("secondary") materials or for energy production. The use of secondary raw materials conserves natural resources and is thus a contribution towards a sustainable development. The worst case scenario occurs when the atoms of a material are finely distributed over the surface of the earth, or throughout the oceans or into the atmosphere by a process such as incineration. With these considerations in mind, the series of lectures on recycling explore and evaluate material cycles from a materials science standpoint.
