The two vehicles have been in service with Glasgow City Council for the past seven years but have reached the end of their working life.
Councillors agreed to donate two refuse lorries to Malawi, at an executive meeting last week.
The lorries will be taken out to Malawi later this month, and used by Lilongwe City Assembly, the local council there.
Councillor Alistair Watson, executive member for Land and Environmental Services, said the donation is part of a long relationship with Malawi.
He said: "This is the latest example of how Glasgow City Council continues to work with our friends in Malawi towards making a real and sustainable difference. Not only are we donating these two vehicles, we are also sharing with our counterparts in Malawi, the skills and expertise to maximise the potential of the two bin lorries."
Last week, the Evening Times told how 13 pupils from Glasgow's secondary schools were chosen to join an expedition to Malawi. They were followed by a team of construction workers on a mercy mission to provide modern medical facilities.
It was the council's ninth trip to Malawi, and is the latest stage in almost a decade of humanitarian work carried out by Glasgow City Council.
The six-strong squad, including two Commonwealth apprentices and Glasgow City Councillor Paul Carey, worked to transform the former Lilongwe Town Hall into a clinic.
Commonwealth apprentice painter Lee Raeburn, 18,and Commonwealth apprentice joiner Lee Thomson, 19, were selected for the trip.
Lee said: "Being chosen for the Malawi team has really boosted my confidence."
They will also carried out maintenance work at the town's Kamuzu Central Hospital.
