Abstract

Wood presevatives such as creosote, pentaclorophenol (PCP) and chromated copper arsenate (CCA) have been widely used over the years in order to extend wood products service life. CCA was known as most widely used wood preservative chemical in residendial and commercial applications world wide until 2004 volanteered phase out of the chemical from residential use bye the major manufacturers. Over the years CCA treated wood acuumulated in service reaching millions of cubic meters. But there is growing concern about the environmental impacts and increasing difficulty in disposing of treated wood products in many countries. Since disposal of CCA treated wood material poses greater problems than the other treated wood products due to heavy and toxic metal componets of CCA such as chromium and arsenic Traditional disposal methods like landfillig or incineration, both have negative environmental consequences. For that reason the increasing volume of CCA-treated wood products coming out of service requires alternative disposal methods and recycling techniques never tried before. The main purpose of this study, except for traditional methods like landfilling and incineration, is to evaluate the current alternative disposal and recycling methods for CCA treated wood removed from service.

Özet

Ağaç malzemenin kullanım ömrünü uzatmak için kreozot, pentaklorfenol (PCP), bakır krom arsenik (CCA) gibi odun koruyucu kimyasallar uzun zamandır kullanılmaktadır. Özellikle ticari uygulamalarda en çok CCA tercih edilmektedir. CCA'nın formülasyonu 1933 yılında bulunmuştur ve bu tarihten sonra birçok ticari üründe kullanılmıştır. Fakat bir süre sonra bu kimyasalla emprenye edilen ağaç malzemenin birçok ülkede çevreye olan olumsuz etkisinden ve yok edilmedeki güçlüklerinden dolayı kullanımına sınırlama getirilmiştir. Çünkü CCA ile emprenye edilmiş ağaç malzemenin kullanım ömrünü doldurduktan sonra bertaraf edilme sorunu ortaya çıkmaktadır. Buna rağmen CCA ile işlem görmüş malzeme halen köprülerde, karayollarında, iletişim hatlarında kullanılmaya devam etmektedir. Geleneksel bertaraf edilme metotlarından toprağa gömme ve yakma oldukça önemli çevre problemleri oluşturmaktadır. Tüm bunların sonucu olarak kullanım ömrünü doldurmuş emprenyeli ahşap malzemenin artışı ile bu malzemenin bertaraf edilmesi ya da yeniden kullanılmasına yönelik farklı metotlar geliştirilmiştir. Bu çalışmada kullanım ömrünü doldurmuş emprenyeli ağaç malzemenin geleneksel yöntemler dışında geri dönüşümü için kullanılan alternatif metotların değerlendirilmesi ve tanımlanması amaçlanmıştır.
