A 25-year-old Dutchman named Boyan Slat, alternately hailed as by the publication Maritime Executive, has for years waged war against plastic pollution in the world’s oceans. “an ocean action hero” and a “wunderkind” It is a foe, Maritime Executive noted, that is “intent on taking over the planet,” which is unfortunately not hyperbole. According to the United Nations, some of plastic waste winds up in the oceans each year, and over time it breaks down into microplastics. There are some of the latter material beneath the waves, according to a recent study by the Commonwealth Scientific and Industrial Research Organization (CSIRO), and it poses a threat to marine life, and by extension global food chains. eight million tons 16 million tons Slat, who at age 18 founded a nonprofit known as The Ocean Cleanup, first centered his efforts on the , an area twice the size of the state of Texas that stands as the world’s largest concentration of plastic pollution. Now he has turned his attention to the world’s rivers, the source of much of the plastic that finds its way to the oceans. Great Pacific Garbage Patch His weapons of choice are robotics -- starting with a 2,000-foot-long unmanned floating barrier . While the U-shaped apparatus failed on its initial foray toward the Garbage Patch, splitting in two late in 2018, an overhauled version of the same structure was launched in June 2019. It succeeded in bringing home some , which was recycled and beginning in October 2020. The proceeds will be used to fund subsequent cleanup efforts. given the name Wilson 60 bags of trash sold as sunglasses As for the rivers, Slat’s organization earlier this year deployed called “Interceptors” to waterways in Malaysia, Indonesia and the Dominican Republic, with plans to hit the world’s 1,000 most polluted rivers by 2025. solar-powered autonomous trash collectors "We accept that we won't deliver magic in one go,” he told CNN. “But we're doing this, step by step." Slat is far from alone in using robotics in the fight against pollution. Other enterprises have, in fact, developed bots that can or . While these robots might not look as futuristic as robots in classic sci-fi movies, they have proven to be effective, no matter their use. consume water pollution collect river trash those that can plant trees 10 times faster than humans to those that can monitor plant growth in adverse weather conditions. From those that can monitor coral reefs to those that can kill invasive species, and even those that venture into sewers to reduce carbon emissions. They range from Particularly important are those robots used to alleviate air pollution, which according to the World Health Organization around the world every year, and leaves 90 percent of the global population breathing unhealthy air. That led the Integral Platform for Climate Initiatives to partner with Russia’s ITMO University in 2018 to develop to monitor air quality (as well as bots to gather data about water quality). kills seven million people drones equipped with sensors Similarly equipped drones were in 2019, as air pollution is a particularly serious problem there. While air-quality evaluations had previously been performed by those on the ground, the drones’ sensors allowed for an in-depth examination of such things as air temperature, atmospheric pressure, humidity and levels of various gases, including carbon monoxide and carbon dioxide. tested in Greece And in Thailand, meanwhile, a fleet of drones was deployed in 2019, in an attempt to spray pollution out of the sky. These aircrafts dispensed water and a “non-hazardous chemical spray,” , and government officials claimed that the drones were able to lower the level of a particularly harmful toxin. according to the Bangkok Post But robotics are truly poised to make a wide-ranging impact. Consider, for example, the developed by MIT in partnership with the Woods Hole Oceanographic Institution (WHOI). They measure ocean depth, detect leaked chemicals or collect other samples of interest. While previous efforts in this realm have suffered from a lack of efficiency or accuracy -- i.e., the robots tended to explore uninteresting areas and/or net useless samples -- this updated technology uses probability to find the most promising places. robotic boats One robotic boat found the most exposed part of a coral reef in Barbados -- crucial to assessing the impact of climate change -- and another collected as many as eight times as many samples as previous methods. Victoria Preston, one of the authors of a 2019 paper on robotic boats, that with the older technology, “it’s easy to think you’ve found gold, but really you’ve found fool’s gold.” Now, that is far less likely. told SciTechDaily Elsewhere, robots have helped improve factories through automated processes that measure energy efficiency and environmental dangers. Through IoT-based monitoring robots can assess toxicity levels in factories and on the field. This type of can reduce greenhouse gas emissions and waste. Robots can even sort through materials to determine which parts can be recycled. environmental monitoring But back to Slat for just a moment. According to a , the problem posed by plastic pollution first caught his attention when at age 16 he saw more plastic bags than fish during a diving trip to Greece. He set aside his aerospace engineering studies to . He now serves as its CEO. 2018 Time Magazine profile found The Ocean Cleanup in 2013 While Slat’s organization, The Ocean Cleanup, has done its part to advance the robotics used in the fight against pollution, Slat is fully aware that the problem won’t be eradicated anytime soon. “Big problems,” he told Time, “require big solutions.” Certainly there will be a need for even bigger solutions. But suffice it to say that the awareness is there, as is the resolve. It is as important a battle as any, and one humankind cannot afford to lose.
