Abstract :In this study, the characterization of polymeric wastes released during production in Eruslu Global group companies and the re-evaluability of these wastes were studied. For this purpose, all polymeric wastes that occur in the production of sanitary napkins, diapers, packaging film and printed packaging film, which are the basic production products of the enterprise; It was determined that it consists of polypropylene, polyethylene insert ignore into journalissuearticles values(LDPE, MDPE, HDPE);, polystyrene, polyethylene terephthalate polymers. Considering that all wastes are not polluted, it has been evaluated that they can be reused to a large extent. In the study conducted for this purpose, it was determined that 20 different waste products emerged depending on the product variety produced in the enterprise. Thermal analysis for each waste was characterized by calorific value, FTIR, XRD, SEM and TG-DSC insert ignore into journalissuearticles values(TGA-DTA); techniques. It was determined that paint was added to polymeric wastes in general. In addition, it has been determined that natural micronized calcite is added to some waste in terms of environmental impact and cost reduction. This article evaluates the crystallinity, structure and surface morphology of polymeric wastes produced during production in Eruslu Global group companies. For this purpose, all polymeric waste products formed in the production of sanitary napkin, diapers, packaging film and printed packaging film, which are the primary production products of the enterprise, were characterized. 20 different waste products produced in the enterprise were selected for evaluation. Waste is rich in polystyrene, polypropylene, polyethylene insert ignore into journalissuearticles values(LDPE, MDPE, HDPE); and polyethylene terephthalate polymers. Each waste was characterized by FTIR, XRD, SEM, thermal analysis and calorific value techniques. As a result of the study, dye additive was detected in the structure of these wastes. When the XRD results were evaluated, it was determined that micronized calcite was added to the polymers to prevent environmental pollution caused by the paint additive. In this way, environmental pollution and production costs are reduced. Calorific values of all samples are in the range of 4292 - 10965 cal/g.
