Microplastics are an increasing global concern, with growing evidence of their presence in water systems. RMIT University researchers have developed a water treatment material that rapidly removes micro- and nanoplastics and some PFAS (per- and polyfluoroalkyl substances), bringing the technology closer to real-world use. The invention builds on the team's 2022 breakthrough in microplastics removal, extending its performance to much smaller particles and more complex wastewater.
