Floating fences in India. Whimsical water- and solar-driven conveyor belts with googly eyes in Baltimore. Rechargeable aquatic drones and a bubble barrier in The Netherlands.
These are some of the sophisticated and at times low-tech inventions being deployed to capture plastic trash in rivers and streams before it can pollute the world's oceans.
The devices are fledgling attempts to dent an estimated 8.8 million tons (8 metric tons) of plastic that gets into the ocean every year. Once there, it maims or kills marine plants and animals including whales,dolphins, and seabirds and accumulates in the Great Pacific Garbage Patch and other vast swirls of currents.
Trash-gobbling traps on rivers and other waterways won’t eliminate ocean plastic but can help reduce it, say officials with the National Oceanic and Atmospheric Administration’s Marine Debris Program.
“It’s just hard to get out to our big open oceans and collect the trash there," said Director Nancy Wallace. “We’d much rather collect that trash closer to shore, which is easier. It's less costly, and we can have that impact before it gets into the ocean.”
Trash is blown, washed or thrown into waterways nearly everywhere. Storm drains funnel in litter tossed onto streets. In places without refuse collection, people use convenient waters to carry trash away.
The science of plastic pollution is new and almost as much in flux as the waters it studies. For instance, a scientist who reported in 2017 that rivers might carry anywhere from 450,000 to 4.4 million tons (410,000 to 4 million metric tons) of plastic a year into the sea also was part of a 2021 study that narrowed the range considerably, with an upper limit of nearly 3 million tons (2.7 million metric tons).
“Compared to other pollutants ... available data on plastics is still scarce,” Christian Schmidt, of the Helmholtz Centre for Environmental Research in Leipzig, Germany, wrote in an email.
D.C. Sekhar of Bengaluru, India, designed a low-tech trap for rivers in his country after he left a career in commercial shipping.
As an oil tanker captain, “I had traveled around the world and seen waterbodies that were fairly clean,” while trash fouled India’s, he said.
Wanting something modular, inexpensive, easy to maintain and able to withstand monsoons, he designed stainless steel mesh fences that extend above and below aluminum floats 3.9 feet (1.2 meters) long.
Sekhar's AlphaMERS Ltd. has installed big floating barriers across rivers at eight southern cities from Hyderabad to Tuticorin. Each is angled to guide trash to a riverbank where excavators pile it into dump trucks.
Eight traps on India’s Cooum River at Chennai, costing about $120,000 total, corralled about 2,400 tons (2,200 metric tons) of plastics and 21,800 tons (19,800 metric tons) of other trash and floating plants in 2018, their first year in position, said Sekhar.
The system with the biggest fan base may be the anthropomorphized Trash Wheels at the mouths of four Baltimore watersheds.
“We’ve got 100,000 followers across major social media platforms,” said Adam Lindquist, vice president of programs and environmental initiatives for the Waterfront Partnership of Baltimore, which owns three devices.
“They are a really great model for how to get the public involved and attentive to the issue,” MaryLee Haughwout, then acting director of NOAA's Marine Debris Program, said in April. The program has helped pay for trash traps in the Anacostia River outside Washington, D.C., and the Tijuana River estuary in California and Mexico but is not involved with the Trash Wheels.
Lindquist said Mr. Trash Wheel has inspired fans to begin recycling or join trash cleanups, and its trash collection data helped convince the Baltimore City Council to ban foam food containers, effective October 2019.
The number of foam clamshells and cups collected by Mr. Trash Wheel has plummeted from an average of more than 147,000 a year from 2015 through 2018 to 26,760 in 2021, according to data on the website.
The devices use ancient and modern technology to run rakes and a conveyor belt that move floating trash into barge-mounted dumpsters. Usually, the current carrying bottles and cigarette butts also turns a water wheel for power. When the current slows, a solar-powered water pump spins the wheel.
Together, Mr. Trash Wheel, Professor Trash Wheel, Captain Trash Wheel and Gwynnda the Good Wheel of the West, named for Gwynns Falls, have taken in more than 2,000 tons (1,800 metric tons) of trash, including 12.6 million cigarette butts and nearly 1.5 million plastic bottles. They are turned on only during and after rainstorms, when large amounts of trash show up.
Mr. Trash Wheel and his younger “relatives” have curved sailcloth shells above their workings, a water wheel on one side, and sport 5-foot (1.5-meter) googly eyes. Each has a personality profile on the web, and Mr. Trash Wheel has an active Twitter account.
A similar device called Wanda Díaz is being installed on the Juan Díaz River at Panama City, Panama by nonprofit La Marea Verde. It won't have googly eyes but will have AI software to analyze the trash on its conveyor belts.
Larger, entirely solar-powered conveyor belts have been designed for Ocean Cleanup founder Boyan Slat, who is now testing those $775,600 “Interceptors” for river trash.
In The Netherlands, Bubble Barrier Amsterdam pumps compressed air through a perforated tube set across the River IJ at Westerdok, where several canals flow into the river. The tube is set diagonally to direct trash to a rectangular collecting device near the shore.
The WasteShark, a boxy 5 foot, 2 inch long (157 centimeter) aquatic drone, was developed about 35 miles (57 kilometers) away in Rotterdam. A drone's hold can accommodate 42 gallons (160 liters) of trash, floating plants and algae, according to RanMarine Technology. They can operate up to eight hours on a charge.
More than 40 have been sold worldwide to buyers in a dozen countries including the U.K, U.S., Nigeria and Singapore, chief operating officer Esther Lokhorst said in an email. Prices start at 23,500 euros (about $25,600) for manually controlled models, more for programmable versions.
Osprey Initiative LLC, of Mobile, Alabama, works on an even smaller scale, setting up floating traps on creeks, canals and rivers in the U.S. Southeast and training local crews to empty the traps, then sort, analyze and dispose of trash.
The company employs about eight to 10 people full-time, with about 30 part-time local workers at projects across nine states, said owner and founder Don Bates. “If you can work with us part time for six months -- and our work is dirty, nasty work -- you come out of it with a changed view of your impact on the environment,” he said.
In the end, said NOAA’s Haughwout, reducing marine plastic will require fundamental changes such as making and using less, particularly single-use plastics such as straws or cutlery; recycling; reusing what you can and choosing reusable items over disposable ones.
“In addition to disposing of waste I like to emphasize awareness,” she said. “I think people don't understand how they contribute.”

From the first antivirus program in the 1970s to the zero-trust protocols of today, security has evolved over the years as developers strive to stay one step ahead of hackers.
Major automakers are asking Congress to lift the cap on how many people can receive tax credits for buying a hybrid or fully electric vehicle. Currently the number of tax credits allowed is capped at 200,000 per company. General Motors and Tesla have already reached the cap and Toyota is close to it. In a letter to leaders of the Senate and House of Representatives on Monday, the chief executives of Ford, Toyota, GM and Stellantis asked that tax credits be extended to anyone who seeks to buy a qualified vehicle. General Motors and Tesla have already reached the cap and Toyota is close to it. Automakers say they want the cap lifted until “the EV market is more mature,” without giving a time frame.
Automakers reported nearly 400 crashes of vehicles with partially automated driver-assist systems, including 273 involving Teslas, according to new statistics from U.S. safety regulators. But the National Highway Traffic Safety Administration cautioned Wednesday against using the numbers to compare automakers, saying it didn’t weight them by the number of vehicles from each manufacturer that use the systems, or how many miles those vehicles traveled. Automakers reported crashes from July of last year through May 15 under an order from the agency, which is examining such crashes broadly for the first time.
Wall Street opened the week with heavy losses that put the benchmark S&P 500 at a level considered to be a so-called bear market. Rising interest rates, the war in Ukraine and China's economic slowdown are leading investors to reconsider what they’re willing to pay for a wide range of stocks, from high-flying tech companies to industrial conglomerates. Big swings have become commonplace and Monday was no exception, with the S&P 500 falling 3.9%. It’s 21.8% below its record set early this year and so now is in a bear market. The Dow industrials sank 2.8% and the tech-heavy Nasdaq composite tumbled 4.7%.
Bridging the digital divide has become a priority for Louisiana since the COVID-19 pandemic showed the crucial role high-speed internet plays in the state’s education and economic systems. The Advertiser reports although federal investments are aiming to bridge that gap, the funds can only go so far without an increase in the number of workers capable of building and installing high-speed internet infrastructure. Internet infrastructure company System Services and LUS Fiber are working with South Louisiana Community College to launch a new fiber-optic install technician program this summer to meet the region's workforce needs. The school’s new program is expected to launch at SLCC’s Crowley campus in July. It has room for up to 30 students for an 18-to-20 week course.
The price of bitcoin and other cryptocurrencies have tumbled after the major crypto lender Celsius halted all withdrawals citing "extreme market conditions." It is the second collapse of a part of the crypto world in the last two months. The stablecoin Terra imploded in early May, erasing tens of billions of dollars worth of value in a matter of hours. Bitcoin was trading at roughly $23,400 Monday afternoon, down more than 16% in the past day. Ethereum, another widely followed cryptocurrency, was down more than 20%.
Taser developer Axon said this week it is working to build drones armed with the electric stunning weapons that could fly into schools and “help prevent the next Uvalde, Sandy Hook, or Columbine.” But its own group of technology advisers quickly panned the idea as a dangerous fantasy. The publicly traded company, which sells Tasers and police body cameras, floated the idea of a new police drone product last year to its artificial intelligence ethics board, a group of well-respected experts in technology, policing and privacy. Some of them expressed reservations. But they did not expect Axon’s Thursday announcement that it wants to send those Taser-equipped drones into classrooms.
The Massachusetts Bay Transportation Authority is going to tackle the nuisance of public urination with technology. The MBTA is launching a pilot program this summer in which urine detection sensors will be placed in four downtown elevators. The data will be collected for several months with a goal of creating a system that can alert transit ambassadors to dispatch a cleaning crew. The MBTA said public urination is not only unsanitary but can also damage elevators. The sensors are not a new concept. Nearly a decade ago, the Metropolitan Atlanta Rapid Transit Authority launched a program that triggered strobe lights, alarms and alerts to MARTA police when urine was detected.
The Biden administration has accused three U.S. companies of sending China blueprints and technical drawings for satellite and rocket technology and other defense prototypes. The Commerce Department leveled the allegations as it blocked the three companies from exporting items to foreign countries for 180 days. That punishment, known as a temporary denial order, is regarded as among the most severe civil sanctions available to the department. The companies provide 3-D printing services. The Commerce Department says customers would send blueprints and drawings to the companies that they wanted printed — and the companies in turn would send that work to China, presumably as a way to cut costs.
The federal government is taking the first step to set up a program that could offer more than $7 billion of loans to repair aging dams across the country. The U.S. Army Corps of Engineers published a proposed rule Friday for the program, which could be open for applications in 2023. The Corps' Water Infrastructure Financing Program was authorized under a 2014 law. But it hadn't been set up because it lacked funding. A series of laws adopted over the past 18 months finally provided that funding. The safety of the nation's 92,000 dams has come under increased scrutiny in recent years after some high-profile failures forced evacuations.
