Plastic pollution is ubiquitous – and an especially serious and confounding problem in the world’s oceans, where immeasurable amounts of plastic debris are scattered. A feasibility study is underway to build and test a network of fixed vessels with winglike, floating booms that could potentially remove 55 shipping containers worth of plastic per day. Called Ocean Cleanup Arrays, the network would be solar-powered and use currents to divert plastic into the vessels to store for later removal and recycling.
