The bleaching process is one of the most sensitive stages in pulp production — and the presence of metal ions such as iron, manganese, and copper can completely compromise the efficiency of hydrogen peroxide, the main bleaching agent. These metals catalyze undesirable reactions, generating highly reactive hydroxyl radicals that degrade both lignin and cellulose, increasing peroxide consumption, reducing pulp yield, and impacting the final brightness quality. This is where Eco
