| Abstract | ||||
| ONE of the greatest considerable problems of the leather industry is waste generation. About 30% of leather substance processed in tanneries is rejected, mainly after shaving process, in the form of protein waste containing about 10–15% chromium (III). This waste is generally deposited and burned causing hazards to all environment; man, plant and animal. In this work; this waste will be grinded to nanosize, treated with flame retardants then added as filler during the formation of carton sheets. The prepared carton sheets were evaluated using scanning electron microscope (SEM) and thermal gravimetric analysis (TGA). Furthermore, the physical properties as basis weight, sheet thickness, airermeability, density of paper sheet were evaluated. The optical properties of the prepared carton sheets were examined. In addition, the mechanical properties (breaking length, tear factor and burst factor) of the prepared carton sheet were assessed. Moreover, the carton sheets were examined as fire retardants materials. Therefore, these carton sheets can be used as materials for packaging applications. | ||||
