The present paper deals with a targeted modification of two kinds of alternative additives - waste from glass production and  natural mineral filler and explores their effect on the properties of polymeric materials. In the function of first alternative filler sludge from weighing the ingredients of glass batch in the glass production was used. The second used filler was natural aluminosilicate material based on zeolite (clinoptilolite). These alternative fillers have been modified in order to increase their efficiency, using the silanes: 3-aminopropyl-triethoxysilane, bis(triethoxysilyl)propyl-tetrasulfide and 3-(triethoxysilyl)propyl-methacrylate. Prepared modified fillers were mixed into rubber compounds as partial replacement of commonly used filler – carbon black. The influence of prepared fillers on rheoloy and curing characteristics of rubber compounds and also on physical and mechanical properties of vulcanizates has been studied. Obtained results of measured characteristics of polymeric systems containing prepared alternative fillers were compared with the results obtained in the case of reference rubber compound with a commertially used filler – carbon black.
