Problem addressed

Microplastic pollution is raising increasing concern over its impact to natural environment, especially in ocean, and its potential adverse effect to human health. This project develops a novel approach using physical treatment to separate microplastic fibres from sewage water discharged from industrial laundry.

Innovation
  • Unlike existing filtration processes, the system enables continuous water treatment and easy collection of microplastic fibres by its acoustic manipulation technique
  • A special design chamber that facilitates waterflow and collection of microplastic fibres
Key impact
  • Reducing microplastic pollution generated from industrial laundry 
  • Relieving threat to marine wildlife
Award
  • Silver Medal in the Special Edition 2022 Inventions Geneva Evaluation Days
Application
  • Relieving microplastic pollution to marine ecosystem
