And some plastic-heavy industries are trying to become solution leaders. The 2020 World's Most Valuable Brands. (Sandy Huffaker for The Washington Post), The Ocean Cleanup ship comes into port in Vancouver in December, when it displayed the results of its first successful trash collection from about 1,100 miles off the California coast. They estimate about 100 kilograms of plastic per square kilometer in the areas that are most dense. If I had more insight into the chemistry, I may have biased the analysis with my viewpoint.". They published their findings in the journal Nature Communications. No single solution exists. Apart from any fair dealing for the purpose of private study or research, no Cuiffi added that machine learning—and data science, in general—is also helpful for this type of interdisciplinary research. “We realized it was not just about the physical quality of the material, but it’s about the emotional quality,” said Slat, whose TED talks became a viral sensation and drew wealthy investors to his cause. Plastic pollution threatens marine life, humans and ecosystems. ... Two-Time World Series Champion Hunter Pence Joins Team Ocean September 18, 2020. Many groups are grass-roots endeavors. HERSHER: And if there's plastic on the surface and all the way at the bottom of the ocean on the seabed, there's probably plastic in between. It’s part of the problem,” said Andrew McAfee, a scientist at the Massachusetts Institute of Technology and an expert in environmental economics. Plastic litter in the ocean is a huge environmental problem. PABORTSAVA: If we're missing 99% of the plastic that we thought we have put in, it has to be somewhere. (Sandy Huffaker for The Washington Post (Sandy Huffaker/The Washington Post). Like FRED, the sleek, bullet-shaped Interceptor uses conveyor belts to draw waste into onboard bins. Three siblings from Indonesia, with hardware-store ingenuity, built a series of wire-mesh screens to filter discarded plastic out of rivers in their homeland before it reaches open waters. The researchers, who released their findings in a recent issue of Nature Communications, said a number of factors in the ocean can help break down this plastic, including ultraviolet radiation from the sun, wind, waves, seawater, water temperature and bacteria. Its own research, announced this month, suggested that 90 percent of ocean plastic resides within five meters of the water surface, degrading over time into the microplastic that sinks to lower depths. If these actions were born through any single event, it might be the day in August 2015 when a team of Texas researchers encountered an injured turtle off Costa Rica. They also have been found in seafood we eat, our beer and drinking water — even in our feces. Neither your address nor the recipient's address will be used for any other purpose. HERSHER: But when scientists added up all the plastic on the surface of the ocean, there was a lot less than they expected, which Pabortsava says is not good news. HERSHER: And those tiny bits eventually make it back to us humans in our air, our water and our food. “We all need to do our part,” said Susan Baer, a former management consultant who abandoned retirement to found Clear Blue Sea four years ago. Medical Xpress covers all medical research advances and health news, Tech Xplore covers the latest engineering, electronics and technology advances, Science X Network offers the most comprehensive sci-tech news coverage on the web. "We started with basic data analysis to explore and sort through the data, then we moved on to predictive machine learning to help us elucidate patterns and trends," said Cuiffi. Click here to sign in with Stores and cities started to impose bans. While knowing the molecular structure of the more susceptible plastics could give engineers a chance to develop plastics with less environmental impact, Mathers said that economics of producing those plastics at scale would still be an issue. Exactly how much lies in our oceans is unknown. (Sandy Huffaker for The Washington Post) RIGHT: Zane Allen makes adjustments to one of FRED's flotation devices during its first maneuvering on the water. Its development began under wraps in Rotterdam, the Netherlands in 2015, about a year before Baer started Clear Blue Sea in San Diego with far more modest resources. “Recycling is not part of the solution of ocean trash. According to the Ocean Conservancy, there are more than 150 million metric tons of plastic in the ocean, with 8 million metric tons more entering the ocean each year. According to Mathers, the study also showed how data science and materials science can contribute to solving issues that may have once been considered outside of their fields. Researchers from Penn State New Kensington performed a machine learning analysis on how plastics break down in ocean conditions. ”. ... PPE adding to oceans' plastic burden. Wait, How Much Microplastic Is Swirling in the Atlantic? We do not guarantee individual replies due to extremely high volume of correspondence. Your opinions are important to us. Otherwise, “this stuff is never going to go away. The ingestion of marine plastics ... are found in the ocean. China is the worst -- with about 2.4 million tons. Sailor Mary Crowley’s Ocean Voyages Institute recruits mariners to tag debris with satellite trackers so it can be easily retrieved later. "The machine learning helped us to determine key relationships and to develop rules for predicting plastic behavior.". Enter FRED, a future vacuum of the seas. In fact, because making virgin plastic is still so inexpensive, the commercial value of recycled plastic is so low that it has become worth far less than the cost of doing business. The amount of plastic dumped into the ocean has been increasing, according to a new study, and the problem will probably get worse. Keep supporting great journalism by turning off your ad blocker. "From the literature, we were able to get information about the physical properties of the plastic that are in the ocean, for instance, molecular weights, the glass transition temperature, the amount of crystallinity, but considering the molecular composition was an overlooked opportunity. No employee draws a salary, although next year the company hopes to have 10 paid staff and raise $2 million in funding. Its next testing sites might be San Diego Bay and the heavily polluted Tijuana River. The next version will have to be stouter, more efficient and sit higher above the waterline. They were doing real interesting work, but from a materials standpoint, no systematic studies were available.". NPR's Rebecca Hersher reports on people who did that. Beach cleanups, anti-pollution campaigns and recycling programs are part of what she calls “greenwashing” — a distraction and ultimately doomed to fail. The size estimate is a bit misleading since the patch does not have a clear boundary and exists in the north Pacific as well as to the south. And previous studies indicate that there is a lot of plastic that is present at the seabed already. Get weekly and/or daily updates delivered to your inbox. Most stuff got away, in part because the vessel unexpectedly created its own eddies that scattered items just before they could reach the conveyor belt. FRED was pulled up the boat ramp, strapped onto a trailer and towed back to the warehouse, its future life at sea still far on the horizon. By using our site, you acknowledge that you have read and understand our Privacy Policy It's just hard to economically compete with polyethylene and polypropylene, which are the most-used plastics in the world. Almost 100 unpaid interns from UC San Diego and other local colleges have contributed their time. So much of this plastic is ending up in the ocean that in just a few years, we might end up with a pound of plastic for every three pounds of fish in the sea. “We’re just happy that it floats,” joked Justin Ho, a mechanical engineering major at the University of California at San Diego, who took the first turn at remotely steering the prototype around the bay using a modified video-game controller. Solar panels were mounted like an awning atop the aluminum frame. (Sandy Huffaker for The Washington Post), The engineering team behind FRED calibrates its computer before sending the vessel into action. He and the others kept FRED within 100 feet of the boat ramp. They found that certain types of plastics did break down quicker than others when subjected to these conditions. "This study took a wide range of physical property data, in combination with a metric that would quantify the composition of molecular structures and used that to try to figure out the most important aspects of plastic degradation in the ocean.". There are so many types of plastics and so many experimental conditions, machine learning became instrumental in helping the researchers both sort through the large amount of data, as well as classify that information, according to Joseph Cuiffi, an assistant teaching professor, who worked with Mathers. "One of the things we were interested in finding out is what is going to happen to the large quantity of plastic that is in the ocean," said Mathers. It is more of a moral issue now, more than it ever was, which makes it a lot like global warming. You can unsubscribe at any time and we'll never share your details to third parties. About 20 engineering students and others gathered in the morning chill to launch a cockeyed-looking vessel, mechanical guts fully visible, into the still water. and Terms of Use. (Darryl Dyck/Canadian Press/AP), FRED's test run in Mission Bay made clear the fixes needed by the Clear Blue Sea team before it can begin work on a bigger prototype. She says a lasting solution will require producers, not consumers, to shoulder the responsibility and cost of managing plastic waste. They also plan to make their blueprints public to accelerate research. And they offered easy targets for its first foray, tossing table-tennis balls, Styrofoam tubes and painted water bottles into the water. Living in an age of plastic, we have become plastic. We became responsible when we realized what was going on. Since coming to NPR in 2011, she has covered the Ebola outbreak in West Africa, embedded with the Afghan army after the American combat mission ended, and reported on floods and hurricanes in the U.S. She's also reported on research about puppies. "I had been interested in sustainability, sustainable materials and this idea of green chemistry for a long time," said Mathers. Help was enlisted by word of mouth. Members of the Institute for Computational and Data Sciences and Materials Research Institute helped the team by providing access to machine learning tools.
