Novel device for collecting microplastics

Read the full story at Azo Cleantech.

Microplastics (MPs), plastic debris smaller than 5 mm, implicitly destroy the environment. Traditionally, they have been collected and removed from water via mesh filtration, which is ineffective. In this regard, scientists from Japan created a high-enrichment microfluidic system that uses acoustic focusing to collect and remove 10–200 μm MPs from wastewater without recirculation. On test samples, its collection rates and enrichment ratios ranged between 70 and 90% and 50 and 100%, respectively.
