Giant plastics collector about to set sail for Great Pacific Garbage Patch

The video explains a plastic scooping system in Alameda, CA, designed to trap plastics in the Great Pacific Garbage Patch. Made from HDPE plastic, it is flexible yet rigid enough to form a U-shaped barrier. A nylon screen catches plastics without harming marine life. Anchors stabilize the device, allowing it to move slower than the current, enabling garbage collection. Boats collect the plastics every 6 to 8 weeks for recycling.

How does the nylon screen function in relation to marine life?

What is the process for collecting the plastics once they are trapped by the device?
