Endüstriyel Atık Çamurlardan Elde Edilen Vitrifiye Ürünlerle İlgili Bir Değerlendirme

Endüstriyel faaliyetler sonucu oluşan arıtma çamurlarının geri kazanımı, arıtımı veya bertarafı tüm dünyada en önemli çevresel sorunlar arasındadır. Atık çamurların yönetiminde yaygın olarak kullanılan yakma, depolama, susuzlaştırma veya tarım alanlarında kullanma gibi yöntemler bu atıkların içerisindeki ağır metallerin uzaklaştırılmasında yetersiz kalmaktadır. Bu atıkların çevre için risk oluşturması ve arıtma maliyetleri gibi sorunların yanı sıra doğal kaynakların da her geçen yıl azaldığı düşünüldüğünde, oluşan atık çamurların değerlendirilerek ikincil malzemelere dönüştürülmesinin önemi artmaktadır. Bu bağlamda vitirifikasyon yöntemi, atıklardan yapı malzemeleri (cam-seramik, tuğla, pigment vb.) üretmenin yanı sıra atıkların içerisindeki ağır metallerin stabilizasyonunu da sağlayan, döngüsel ekonomi yaklaşımıyla örtüşen bir yöntem olarak dikkati çekmektedir. Bu makalede, endüstriyel artıma çamurlarının katma değeri olan ürünlere dönüştürülmesi noktasında, arıtma çamurlarının vitrifikasyonu ve vitrifiye ürünlerin kullanım alanları ile ilgili çalışmalar incelenmiştir.

Anahtar Kelimeler:
