Eczacıbaşı Yapı Grubu Bozüyük Kampüsünden Çıkan Atıkların Geri Dönüşümü

Bu çalışmada, porselen karo pişmiş atığı ile birlikte SSG ve kaplama malzemeleri üretiminden çıkan arıtma filterpres atığının porselen karo bünye reçetesinde kullanılabilirliği araştırılacaktır. Standart bir bünye karışımından başlayarak, atıkların kullanıldığı farklı reçeteler çalışılmış ve bunlardan iyi sonuç veren iki tanesi bu çalışmada anlatılmıştır. Atıkların hazırlanan kompozisyonun sinterleme, pişme küçülmesi, renk değişimi özellikleri üzerindeki etkisi çalışılmıştır ve analiz sonuçlarına göre reçeteye ilave edilebilecek optimum miktarlar belirlenmiştir. Söz konusu proje gerçekleştikten sonra, daha az doğal kaynak kullanımı dolayısı ile reçete maliyetleri azalmıştır, Bozuyuk kampusunde bulunan atıkların kullanımı sonucu kampüse taşınan hammadde miktarı azalmıştır ve bunun sonucu olarak taşımacılık sebebi ile ortaya çıkan emisyon azalmıştır.

Recycling Ceramic Production Wastes of Eczacibasi Building Group Bozuyuk Campus

The possibility of use of porcelain stoneware tile fired waste and purification filter press wastes which occur in the production of sanitaryware and coating materials, by their incorporation in a porcelain stoneware body mix, was studied. Starting from a standard body mix, several modified body mixes were prepared with these wastes and two of them was given in present study. The effects of wastes on sintering, firing shrinkage, water absorption, colour variation properties of prepared compositions was studied and the amount of optimum entry to recipes was identified by changing according to analysis results. When the subject project occurred, recipe costs decreased with lower natural resource use, raw material that was carried to campus decreased with utilization of wastes in Bozüyük campus, as a result, CO2 emission that was because of transporting decreased. Decreasing the waste amount that needs to be sent to local garbage collection centers decreased environmental and visual pollution and this helps to leave a cleaner environment the next generations. © Afyon Kocatepe Üniversitesi 1. IntroductionSanitaryware articles areporcelain products generally produced from “vitreous china” and desired to have water absorption values of less than 0.5%. After firing, the major phases of vitreous china are mullite and glass; there is also a moderate proportion of unreacted silica, normally in the form of α-quartz and minor amounts of porosity (Carty and Senapati 1998; Bernardin and Riella 2006; Tuncel et al. 2011). Sanitaryware ceramics constitute 7% of the world’s ceramic market when monitored from the economic point of view
