86 million metric tons of plastics end up in the oceans every year, with devastating consequences for marine life, nature and, ultimately, for us humans. The vast floating patches of plastic carpeting the water’s surface, some as large as entire countries, are only the tip of the iceberg. Around 90 percent of this garbage ends up on the seabed. The Fraunhofer Center for Maritime Logistics and Services CML and an international network of partners want to be the first to tidy up this mess with a project called SeaClear. An interview with project managers Johannes Oeffner and Cosmin Delea follows.
