Alternatives <strong>to</strong> bleaching<br />
with hypochlorite<br />
Case illustration:<br />
Bleaching with hydrogen<br />
peroxide<br />
Concept In some companies, bleaching with sodium hypochlorite (NaOCl) is still taking<br />
place. This agent is environmentally hazardous, partly because of <strong>the</strong> risk<br />
for formation of free chlorine and partly because of formation of chlorinated<br />
organic compounds in <strong>the</strong> waste-water. In many cases, bleaching with hydrogen<br />
peroxide could be done but <strong>the</strong> possibilities and consequences of this substitution<br />
should be judged in each case.<br />
Improvement potentials Reduction of environmental impacts.<br />
Relevance All companies doing hypochlorite bleaching.<br />
