Drones tackle Everest's trash crisis, hauling gear up and garbage down
It's often called the 'world's highest garbage dump.'
Some estimate 50 metric tons of trash remain on Mount Everest due to decades of climbing and lax regulations.
But these unmanned aerial vehicles are being utilized to try to clean up one of the world's most remote locations.
Nepal-based Airlift Technology is addressing this crisis by deploying drones to deliver supplies up the mountain and then remove waste on the way down.
After successful trials in 2024, the company estimates it removed over one metric ton of trash between March and May 2025.
"The main intention, of course, was like bringing the garbage because tons and tons of garbage are on Mount Everest, which means, like, this was our main motive to have a drone delivery in Mount Everest," Milan Pandey, Airlift Technology co-founder, said.
The drones, made by a Chinese manufacturer, are capable of quickly transporting up to 33 pounds of critical supplies, including oxygen bottles, ladders, and ropes.
''Because the interesting thing is, from Base Camp to Camp One, it takes 7 to 9 hours for climbers to reach. And our drone can reach over there within 3 minutes."
That helps sherpas climb difficult sections of the mountain, such as the Khumbu Icefall, a perilous passage riddled with crevasses and icefall, without carrying large amounts of equipment.
It's a welcome innovation for Nepalese mountaineer Nima Rinji Sherpa.
''I think this is very interesting and very good in a way, because it is humanly impossible to bring all the trash down by cutting through the Khumbu Icefall to the South Col. So I think, yes, right now we're using these drones by Airlift Technology, which is very innovative in a way that it also saves people's lives and it makes it easier for everyone to bring down the trash,'' he said.
While other Everest cleanup operations are ongoing, Airlift Technology hopes drones will provide a new tool in efforts to tackle the mountain's trash scourge. — Reuters

China bans uncertified and recalled power banks on planes
BEIJING - China's aviation regulator will from Saturday ban passengers from carrying power banks without Chinese safety certification markings, as well as those recently recalled by manufacturers because of safety concerns. The move, which applies to anyone boarding a flight in China, follows a series of incidents globally involving lithium battery products, including power banks, overheating on planes. South Korea said a spare power bank was a possible cause of a fire that engulfed an Air Busan plane in January, and in March a Hong Kong Airlines flight from China to Hong Kong was forced to land in China due to a fire in an overhead baggage compartment. Lithium batteries in devices such as laptops, mobile phones, electronic cigarettes and power banks can produce smoke, fire or extreme heat when manufacturing faults or damage cause them to short circuit. They are a growing concern for aviation safety as passengers carry more battery-powered items on flights. Last year, three incidents every two weeks of overheating lithium batteries on planes were recorded globally by the US Federal Aviation Administration, compared to just under one a week in 2018. China's Civil Aviation Administration said on Thursday power banks must be clearly marked with "3C" certification, short for China Compulsory Certification, which authorities require for products that could impact health, safety, and environmental protection. Several leading power bank manufacturers in China including Anker and Romoss have this month recalled batches of battery products due to safety concerns. China's market regulator has revoked or suspended the 3C certification of several power bank and battery cell manufacturers. Since the Air Busan incident, airlines globally have been tightening power bank rules. Aviation rules generally say power banks should be carried in cabin baggage, but increasingly airlines are banning their use on board and say they must be kept within view to spot any problems. China has since 2014 forbidden passengers from charging devices using power banks during flights. Southwest Airlines at the end of May became the first US airline to say portable charging devices must be visible while in use during flight. — Reuters

AirAsia MOVE gets P6M fine for ‘excessive airfares'
Flights, accommodations, and rides booking platform AirAsia MOVE was slapped with a P6 million penalty after government officials flagged it over alleged 'excessive' one-way plane tickets. In a statement on Friday, the Department of Transportation (DOTr) said it welcomed the Civil Aeronautics Board's (CAB) 'swift action' in penalizing AirAsia MOVE 'after it posted excessive and unreasonable airfares on its booking platform.' 'The P6-million penalty imposed on AirAsia MOVE sends a clear message: the government will not tolerate any form of abuse to Filipino passengers,' the DOTr said. 'The DOTr will continue to protect the rights of the commuting public and to hold accountable those who violate established consumer protection regulations,' DOTR added. GMA News Online reached out to AirAsia MOVE for comment. The story will be updated once a response has been received. Previously, AirAsia MOVE chief executive officer Nadia Omer said it does not manually set or manipulate airfares, as it clarified that it is an online travel agency that displays flight inventory and pricing as provided by its authorized upstream suppliers. 'The discrepancies in fare displays for certain routes, including domestic flights operated by Philippine Airlines, were caused by temporary data synchronization issues with flight pricing partners,' she said. Omer also said that they have taken 'immediate steps' and brought up the matter with the third-party pricing provider for resolution and have since enhanced safeguards to prevent a repeat of the situation.. 'MOVE has been working closely with relevant authorities and is fully compliant with all regulatory requirements applicable to Online Travel Agencies (OTAs) operating in the Philippines,' she said. Transportation Secretary Vince Dizon earlier said he was seeking the filing of charges and closure of AirAsia MOVE, citing Leyte Representative Richard Gomez's report that the lawmaker and his wife bought two one-way tickets from Tacloban to Manila for P77,704 through the Malaysia-based booking platform. Dizon also said that airline firm AirAsia does not have anything to do with the platform. 'They're affiliated but I don't think AirAsia, in fairness to AirAsia Philippines, no, the airline… I don't think they have anything to do with this,' Dizon said. The controversial flight rates came to light amid the ongoing repair of the San Juanico Bridge, which disrupted movement in the Eastern Visayas causing passenger and cargo fares to spike. —VAL, GMA Integrated News
