Year 2010, Volume: 60 Issue: 1, 50 - 58, 18.02.2010

Abstract

Recycled fibers known as secondary fibers become indispensible raw material for paper industry. In paper industry, recovered paper utilization strongly depends on developments in ink removal process which has rapidly improved. The aim of deinking which is largely a chemical process, is to detach printing inks from the fibers and to remove detached ink particles from the pulp slurry to prevent them redeposition on the fiber surface. Currently, the increase of environmental awareness and energy saving concerns forced paper industry to search a new pursuit as an alternative to chemical deinking. Enzyme applications are among the new technologies that can help the removal of ink to take into considiration of these actual concerns. Even enzymes have been used in the paper industry for various purposes for many years, it is new to use enzymes in deinking applications. Altough the exact mechanism of enzymes is stil unknown, it is certain that enzymes change fibre properties. This study presents how enzymes work to remove ink from the fibers and which parameters are important to obtain the best results. It is clear that along with the positive results in laboratory studies, the use of enzymes in industry will increase and as a result  the enzyme costs will drop to much more reasonable levels.

 

Key words: Recycled fibers, deinking, enzyme,  pulp properties

Mürekkep Giderme Sürecinde Enzimlerin Kullanılması

Year 2010, Volume: 60 Issue: 1, 50 - 58, 18.02.2010

Abstract

Sekonder lif veya ikincil lif olarak adlandırılan atık kağıt lifleri, atık kağıt endüstrisi için
vazgeçilmez bir hammadde kaynağı haline gelmiştir. Kağıt endüstrisinde atık kağıtların
kullanılması mürekkep giderme işlemlerindeki gelişmelere bağlı olarak hızla artış göstermektedir.
Büyük ölçüde kimyasal bir süreç olan mürekkep gidermenin amacı, mürekkebin bağlı bulunduğu
liflerden ayrılarak uzaklaştırılması ve ayrılan taneciklerinin tekrar lifler üzerine yerleşmesinin
engellemesidir. Günümüzde çevre koruma bilincindeki duyarlılıkların ve enerji tasarrufuna yönelik
kaygıların artması, kağıt endüstrisini kimyasal mürekkep gidermeye alternatif yeni arayışlara
yönlendirmiştir. Enzimlerle yapılan uygulamalar, mürekkep gidermede bu kaygıları giderecek yeni
teknolojiler arasında yer almaktadır. Enzimlerin kağıt endüstrisinde uzun süredir çok çeşitli
amaçlarla kullanılıyor olmalarına rağmen, mürekkep giderme amacıyla kullanılmaları oldukça
yenidir. Enzimlerin nasıl bir mekanizma izledikleri tam olarak bilinmemesine rağmen, lif
özelliklerini değiştirdikleri bilinmektedir. Bu çalışma ile enzimlerin mürekkep gidermede nasıl bir
yol izledikleri ve enzimlerle yapılan çalışmalarda hangi değişkenlerin dikkate alınması gerektiği
ortaya konmaktadır. Laboratuvar çalışmalarıyla ilgili olumlu sonuçların alınması, enzimlerin
endüstride kullanımlarını artıracak ve bunun sonucu olarak da enzim maliyetleri çok daha makul
düzeylere gelecektir.
