ClearPreventing Microplastic Release into Oceans through Wastewater Treatment Technologies

It called for targeted development of microplastic-specific treatment technologies.
Análise de técnicas de remediação para a mitigação de micro e nanoplásticos em oceanos com base na revisão da literatura
This review analyzed scientific literature on remediation techniques for removing micro- and nanoplastics from ocean environments, identifying and comparing two key approaches: the first focused on membrane-based methods — ultrafiltration, membrane bioreactors, and dynamic membrane technology — for wastewater treatment, and the second examined nanomaterials as adsorbents. Membrane technologies demonstrated high removal efficiency for micro- and nanoplastics, though each method presents implementation challenges that require further research.
