3D Printed Aquatic Garbage Collectors
Aquatic garbage could be collected and sequestered using "artificial whales" that swim through affected areas "filter feeding" as baleen whales do. They would sort items by size and material using 3D printed electroactive polymers in conjunction with 3D printed plastic filters and other components. Larger sea creatures would avoid them. Smaller ones capable of free swimming which were captured would be given the opportunity to swim out of the tank they were funneled into whereas the garbage would stay behind.
