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 (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 (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 (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.

Hijyenik Ürün Fabrikasında Oluşan Polimerik Atıkların Karakterizasyonu ve Bu Atıklardan Enerji Geri Kazanımı

Abstract

Bu çalışmada Eruslu Global grup şirketlerinde üretim sırasında açığa çıkan polimerik atıkların karakterizasyonu gerçekleştirilmiş ve bu atıkların yeniden değerlendirilebilirliği araştırılmıştır. Bu amaçla işletmenin temel üretim ürünlerinden kadın pedi, çocuk bezi, ambalaj filmi ve baskılı ambalaj filmi üretiminde meydana gelen tüm polimerik atıkların; polipropilen, polietilen (LDPE, MDPE, HDPE), polistiren, polietilen tereftalat polimerlerinden oluştuğu belirlenmiştir. Tüm atıkların kirlenmediği göz önüne alındığında büyük oranda yeniden kullanılabileceği değerlendirilmiştir. Bu amaçla yapılan çalışmada işletmede üretilen ürün çeşitliliğine bağlı olarak 20 farklı atık ürün ortaya çıktığı belirlenmiştir. Her bir atık için termal analiz, ısıl değer, FTIR, XRD ve SEM teknikleri ile karakterize edilmiştir. Polimerik atıklara genel olarak boya katkılandığı belirlenmiştir. Ayrıca çevresel etki açısından ve maliyet düşürücü olarak bazı atıklarda doğal mikronize kalsit katıldığı belirlenmiştir. Bu makalede, Eruslu Global grup şirketlerinde üretim sırasında oluşan polimerik atıkların kristalliği, yapısı ve yüzey morfolojisi değerlendirilmektedir. Bu amaçla işletmenin birincil üretim ürünleri olan hijyenik kadın pedi, çocuk bezi, ambalaj filmi ve baskılı ambalaj filmi üretiminde oluşan tüm polimerik atık ürünler karakterize edilmiştir. İşletmede üretilen 20 farklı atık ürün değerlendirilmek üzere seçilmiştir. Atık, polistiren, polipropilen, polietilen (LDPE, MDPE, HDPE) ve polietilen tereftalat polimerleri açısından zengindir. Her bir atık, FTIR, XRD, SEM, termal analiz ve ısıl değer teknikleri ile karakterize edilmiştir. Çalışma sonucunda bu atıkların yapısında boyar madde katkısı tespit edildi. XRD sonuçları değerlendirildiğinde, boya katkı maddesinin neden olduğu çevre kirliliğini önlemek için polimerlere mikronize kalsit ilave edildiği belirlendi. Bu sayede çevre kirliliği ve üretim maliyetleri azaltılmaktadır. Tüm numunelerin kalorifik değerleri 4292 - 10965 cal/g aralığındadır.
