Abstract:
This paper deals with resource efficiency in the construction industry and the question of how soil and demolition material can be recycled in a quality-related manner. Large quantities of waste materials are produced during civil engineering and demolition work, which are usually sent for low-quality recycling, such as open-cast mine backfilling. Alternatively, the material is often disposed of. A material cycle for excavated material from tunnel construction sites, which was elaborated in the diploma thesis, considers the higher-quality recycling and the associated logistics processes as well as legal principles of material management. This cycle can increase resource efficiency. In addition, costs can be reduced and emissions saved by, among other things, handling transport routes regionally. In a practical example, the new tunnel construction project of the Deutsche Bahn between Dresden and Prague, the excavation volume was first determined and then innovative and creative scenarios were examined in which the excavated soil of the large-scale construction project is to be recycled. In the scenarios considered, valuable resources could be conserved for the practical project and landfilling of the excavated material could be avoided.
