What are Microplastics?
Microplastics are small plastic pieces less than five millimeters long which can be harmful to our ocean and aquatic life.
World's oceans are currently under threat not only from large pieces of plastic trash, but also from minuscule "microplastic" particles – many of which take the form of fibers that are shed by synthetic fabrics as they're being washed. A new system uses sound to help capture those fibers at their source.
This method is called as BAW (Bulk Acoustic Wave).
In lab tests, the BAW setup was found to capture 95 percent of PET (polyethylene terephthalate) fibers, and 99 percent of Nylon 6 fibers.
