What to know about Environmental Pollution (Microplastics)

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.

What happened

New research aims to reduce microfiber pollution released from cruise and hotel laundry Lisa Lock scientific editor Andrew Zinin lead editor Microfiber pollution from large-scale laundry operations is emerging as a significant and largely unseen environmental…

Why it matters

New research led by the University of Portsmouth is using Cleaner Seas Group's industrial filtration technology—already deployed in commercial settings to better understand the scale of the problem and how it can be prevented before it reaches our waterways.

Common ground

The study builds on previous data that revealed more than 700,000 microfibers can be released from clothing during a single domestic wash.
