Environmental Pollution (Microplastics) Industrial Waste Management

New research from the University of Portsmouth is investigating microfiber pollution originating from large-scale laundry operations, specifically focusing on cruise and hotel sectors. The study utilizes industrial filtration technology to measure the volume and composition of microfibers removed from greywater. Researchers aim to provide evidence supporting the effectiveness of filtration systems in reducing environmental discharge.
