For several decades, the methodology of complete destruction organic pollutants via oxidation, i.e., mineralization, has been rooted in real water treatment applications. Nevertheless, this industrially accepted protocol is far from sustainable because excessive input chemicals and/or energy as well unregulated carbon emission. Recently, there have emerging studies on removal a completely different pathway, polymerization, meaning that target undergo oxidative polymerization reactions to generate polymeric products. These collectively shown compared conventional mineralization pathway allows more efficient pollutants, largely reduced chemicals, and suppressed In review, we aim provide comprehensive examination fundamentals process, current state-of-the-art strategies for regulation both kinetic thermodynamic perspectives, resource recovery formed end, limitations process pollutant are discussed, with perspectives future studies. Hopefully, review could not only critical insight advancement polymerization-oriented technologies greener manner but also stimulate paradigm innovations low-carbon treatment.
