Supporters of WasteAid UK have raised £6,400 for the charity, the bulk of it by climbing Mount Snowdon.
Twenty-five people braved the Welsh weather in a sponsored walk organised by fundraiser Sally Talbot.
“It was a great opportunity to get so many people together for WasteAid UK and shows what can be achieved when we work together,” she said.
Andrew Jenkins, recycling officer at Cherwell & South Northamptonshire councils reached the summit with a wheelie bin full of (recyclable) rubbish strapped to his back.
“I wanted to do a little bit more, so I thought carrying a wheelie bin up Snowdon would be tough and a good fit for a charity working in waste management.
“It was hard work, and my legs haven’t forgiven me yet, but it was brilliant getting to the top knowing we had all raised thousands for WasteAid UK. I know that the money raised will be well spent and make a real difference.”
Meanwhile in Devon, Carolyn Couch, waste and recycling manager at the University of Southampton, leapt from a plane in a tandem skydive.
Mike Webster, director of WasteAid UK, said: “This has been an incredible weekend. The response to our first major fundraising events has been overwhelming and demonstrates that people really do recognise the need for proper waste management in developing countries.
”We’re inviting the whole industry to get behind us to help deliver real and lasting change.”
The next big fundraising event will be on 6 August when a team of cyclists led by Matt Slaughter, environmental compliance manager at Matthews (Sussex) will cover 70 miles along the Basingstoke Canal, finishing at London Waterloo Station.
