Kostik soda, soda k\u00fcl\u00fc ve hidrojen peroksit gibi di\u011fer kimyasallarla birlikte, lifleri lignin ve di\u011fer yabanc\u0131 maddelerden ay\u0131rmak i\u00e7in hamurla\u015ft\u0131rma \u00e7\u00f6zeltisinin bir par\u00e7as\u0131 olarak kullan\u0131l\u0131r. Bu i\u015fleme tipik olarak kraft hamurla\u015ft\u0131rma i\u015flemi denir ve yayg\u0131n olarak en yayg\u0131n hamurla\u015ft\u0131rma y\u00f6ntemi olarak kabul edilir.<\/p>\n\n\n\n\n\n\n\n

Kostik soda ka\u011f\u0131t end\u00fcstrisinde \u015f\u00fcphesiz hayati bir rol oynasa da, \u00fcretimi ve kullan\u0131m\u0131 baz\u0131 \u00e7evresel hususlar\u0131 da beraberinde getirmektedir. Kostik soda \u00fcretimi, genellikle b\u00fcy\u00fck miktarda enerji kullan\u0131larak tuz \u00e7\u00f6zeltilerinin elektrolizini i\u00e7erir. Bu i\u015flem sera gazlar\u0131 a\u00e7\u0131\u011fa \u00e7\u0131kar\u0131r ve \u00f6nemli miktarda su t\u00fcketir.

Ayr\u0131ca kostik soda at\u0131klar\u0131n\u0131n bertaraf\u0131, \u00e7evresel etkilerini en aza indirmek i\u00e7in dikkatli bir i\u015flem gerektirir. Kostik soda at\u0131klar\u0131n\u0131n a\u015f\u0131r\u0131 de\u015farj\u0131, su k\u00fctlelerinin ve yeralt\u0131 sular\u0131n\u0131n kirlenmesine yol a\u00e7arak, potansiyel olarak sudaki ya\u015fama ve insan sa\u011fl\u0131\u011f\u0131na zarar verebilir. Bu nedenle, ka\u011f\u0131t end\u00fcstrilerinin uygun ar\u0131tma sistemleri ve sorumlu imha y\u00f6ntemleri de dahil olmak \u00fczere uygun at\u0131k y\u00f6netimi uygulamalar\u0131n\u0131 uygulamas\u0131 \u00e7ok \u00f6nemlidir.
