A trash-collecting machine powered by a water wheel and solar panels has prevented hundreds of tonnes of plastic and other garbage from Panama from littering mangroves and the ocean.
All kinds of trash flow down rivers running through Panama City and end up on the coastline of the Central American nation.
To combat the pollution, the nonprofit Marea Verde Foundation installed a machine called Wanda two years ago to collect and separate trash for recycling.

“We’ve captured 256,000 kilos of waste that would be in the mangroves and sea if it had not been for Wanda,” said Laura Gonzalez, the foundation’s executive director.
The garbage is stopped by a barrier across the Juan Diaz River that runs through Panama City before several workers separate the waste, which is sent by a long conveyor belt to a huge container to be recycled.
Wanda also has solar panels in case the hydropower system that harnesses the energy of the river current fails.
No other river in Panama has a similar system, so tonnes of garbage continue to reach the sea.
The country’s coastal mangroves are a vital resting place for hundreds of thousands of migratory birds, but pollution and urban growth pose a serious threat.
Uncollected garbage litters the streets and residential areas of Panama City and its surrounding areas, while on the coast, there are piles of all kinds of waste.
Panamanian Minister of the Environment Juan Carlos Navarro in July called the state of the rivers an “environmental disaster.”
“We cannot continue polluting our rivers and seas,” Navarro said.
The trash captured by Wanda includes plastic bottles, shampoo containers and soccer balls.
“It’s crazy. We received a plastic unicorn a few days ago,” Gonzalez said.
There are eight other similar facilities around the world, including one in Baltimore, Maryland, but Wanda is the only one of its kind in Latin America, Marea Verde said.
It began operating in September 2022 and captured about 120 tonnes of waste in its first year.
However, the amount of trash dumped in the river continues to increase.
“This year we will probably exceed what we collected in the first year,” Gonzalez said.
A humanoid robot that won a half-marathon race for robots in Beijing on Sunday ran faster than the human world record in a show of China’s technological leaps. The winner from Honor, a Chinese smartphone maker, completed the 21km race in 50 minutes and 26 seconds, said a WeChat post by the Beijing Economic-Technological Development Area, also known as Beijing E-Town, where the race began. That was faster than the human world record holder, Ugandan Jacob Kiplimo, who finished the same distance in about 57 minutes in March at the Lisbon road race. The performance by the robot marked a significant step forward
Four contenders are squaring up to succeed Antonio Guterres as secretary-general of the UN, which faces unprecedented global instability, wars and its own crushing budget crisis. Chile’s Michelle Bachelet, Argentina’s Rafael Grossi, Costa Rica’s Rebeca Grynspan and Senegal’s Macky Sall are each to face grillings by 193 member states and non-governmental organizations for three hours today and tomorrow. It is only the second time the UN has held a public question-and-answer, a format created in 2016 to boost transparency. Ultimately the five permanent members of the UN’s top body, the Security Council, hold the power, wielding vetoes over who leads the
South Korea’s air force yesterday apologized for a 2021 midair collision involving two fighter jets, a day after auditors said the pilots were taking selfies and filming during the flight and held them responsible for the accident. “We sincerely apologize to the public for the concern caused by the accident that occurred in 2021,” an air force spokesman told a news conference, adding that one of the pilots involved had been suspended from flying duties, received severe disciplinary action and has since left the military. The apology followed a report released on Wednesday by the South Korean Board of Audit and Inspection,
An earthquake registering a preliminary magnitude of 7.7 off northern Japan on Monday prompted a short-lived tsunami alert and the advisory of a higher risk of a possible mega-quake for coastal areas there. The Cabinet Office and the Japan Meteorological Agency said there was a 1% chance for a mega-quake, compared to a 0.1% chance during normal times, in the next week or so following the powerful quake near the Chishima and Japan trenches. Officials said the advisory was not a quake prediction but urged residents in 182 towns along the northeastern coasts to raise their preparedness while continuing their daily lives. Prime
