Abstract:
The subject of the work is the determination of the theoretical basis for the further utilisation of existing window pane elements or parts thereof. The development of an implementation concept from the inventory to the dismantling, refurbishment, transport and distribution of these existing window pane elements for subsequent use is the content of the work. The damage patterns resulting from the initial use were compiled and structured as a matrix for the assessment of subsequent use and the scope of repair. The structure of a database, which records the entire process from collection to dismantling, refurbishment and distribution of the window elements, was designed with the aim of quality documentation. In discussions with glass manufacturers, processors and glass recycling companies, the practical and market suitability was discussed. The thesis also addresses the conditions required by law and considerations for improving acceptance of the use of used building components in order to implement the concept. A path is shown that demonstrates the possibility of recycling flat glass with the aim of transferring this material into the float glass process as a raw material. The aim of this work is to keep the high-quality product flat glass and, if possible, the frame element in the actual utilisation cycle for as long as possible. This concept is intended to demonstrate a way of using energy and resources sparingly and reducing CO2 emissions. In this way, the construction industry can make a contribution to the EU's goal of climate neutrality by 2050.
