Summary

Case studies of catalyzed wet oxidation — a process using high temperature, pressure, and chemical catalysts — demonstrated effective degradation of microplastic polymers in water, converting them to smaller organic molecules or CO2. This technology offers a route to complete microplastic elimination from wastewater streams rather than filtration and disposal, which is critical as conventional treatment plants fail to remove a significant fraction of plastic particles.

Microplastic (MP) pollution in water has increased in the last decade, driving the development of technologies for its treatment. The degradation of MP is an effective alternative, since it eliminates them and prevents their accumulation in the environment. In this...
