Around ten tonnes of rubbish has been collected on Everest at the end of this year's climbing season, Nepal authorities said.
Global warming means melting glaciers are revealing rubbish gathered over decades of commercial mountaineering.
The 14-strong team sent by the government spent about six weeks scouring for litter at base camp and at Camp 4 - nearly 8,000 metres up - scraping together empty cans, bottles, plastic and discarded climbing gear.
"We have reached our target this season... we hope we are able to continue what we have started," authorities confirmed.
Army helicopters and porters transported the refuse down to Namche Bazar, the last major town on the route to Mount Everest.
Authorities said some of it will be sent to Kathmandu for recycling.
Fluorescent tents, discarded climbing equipment, empty gas canisters and even human excrement litter the well-trodden route to the summit of the 8,848-metre peak.
"We need to run this programme for few more years, especially at the higher camps, to make the mountain clean," said Pasang Nuru Sherpa, the clean-up team's leader.
Governments on both sides of the mountain have been battling the human waste and trash left by an increasing number of climbers.
Six years ago, Nepal implemented a $4,000 rubbish deposit per team that would be refunded if each climber brought down at least eight kilos of waste, but only half of the climbers return with their rubbish.
In February, China banned non-climbers from accessing its Everest base camp in Tibet in an attempt to clean up its side of the mountain.
Hundreds of climbers reached the summit this season, and the total could go past last year's record of 807 ascents.
