Chip screening rejects were refined with a laboratory type refiner;however, pulp screening rejects were not refined. These materialswere added to commercial fibers with the rates of 10%, 30%. Fiberboards weremanufactured using urea formaldehyde (UF) adhesive. Some properties of thesefiberboards such as water absorption (WA), thickness swelling (TS), surfaceroughness parameters, color change, modulus of rupture (MOR) and modulus ofelasticity (MOE) values were determined. As a result of these, it was foundthat all values showed different trend depending on rates and types of Kraftmill wastes. Generally, the use of thesematerials had positive effects on the panel properties.

Yongaeleme atıkları, laboratuvar tipi bir rafinörde liflendirilirken; hamur elemeatıkları ise rafinör işlemine uğratılmadan kullanılmıştır. Elde edilen lifselmateryaller ticari liflere %10 ve %30 oranlarında ilave edilmiş ve üreformaldehit (UF) tutkalı kullanılarak lif levha üretimlerigerçekleştirilmiştir. Üretilen bu levhaların su alma (SA), kalınlığına şişme(KŞ) değerleri, yüzey pürüzlülük parametreleri, renk değişim değerleri, eğilmedirenci (MOR) ve eğilmede elastikiyet modülü (MOE) gibi bazı özellikleri belirlenmiştir.Bu çalışmanın sonucu olarak, tümdeğerlerin, kraft fabrika atıklarının türü ve kullanım oranına bağlı olarakdeğişim gösterdiği belirlenmiştir. Genel olarak, bu atık materyallerinkullanımının levha özellikleri üzerinde olumlu yönde etkisinin olduğu tespitedilmiştir. CR - Akgül, M. & Çamlibel, O. (2008).
