Oxygen nanobubbles improve cellulose bleaching by distributing oxygen uniformly in pulp suspension and sustaining faster lignin reaction.

Chlorine dioxide and a nitroxyl radical combine delignification and cellulose oxidation in one step, cutting organohalides, energy use, and effluent.

Using sodium sulphate as the main make-up chemical helps pulp mills replace sodium losses, cut caustic use, and reduce fly ash dumping.
