Present Master Thesis deals with the carbon footprint calculation of refractory products. Definitions of the term carbon footprint are given and its intent, its types as well as its calculation approaches are described. Furthermore, refractory products are characterised and their widespread application areas are exhibited. As a matter of fact, so far no standardised method exists for the calculation of the carbon footprint of refractory products. Therefore, the objective of this Master Thesis is to develop a model that enables to assess the carbon footprint of refractories, especially that of shaped refractory products (bricks). Thus, the analysed system, the applied data and the necessary assumptions made are described. This model, which considers diverse life cycle assessment and carbon footprinting standards, is arranged in form of a tool box. This tool box is structured according to the life cycle steps or rather production steps of shaped refractories. The practical application of this model is tested on basis of lining concepts for high temperature resistant aggregates.
