Buckingham Palace is donating its old computers to charity Computer Aid International, which will refurbish them and send them to schools and charities in the developing world.
The palace removes and destroys the hard drives and recycles the constituent raw materials. The remaining parts of the computers are donated to Computer Aid, which upgrades the IT and sends it on.
The charity works mainly in sub-Saharan Africa but also places IT in Asia and South America.
The computers are used in schools, community organisations and universities. Buckingham Palace said its equipment has ended up in a school in Rwanda, a university in Kenya and a charity in India.
The palace has donated more than 1,700 pieces of equipment since 2005, including 700 computers and 640 monitors.
It said, "It is the palace's contribution to make best use of computers once we have finished with them, rather than them going to waste."
Computer Aid International said the palace's donations are making a "significant contribution in enabling disadvantaged communities to actively participate in the global digital economy".
The charity said, "Every PC refurbished by Computer Aid goes on to provide at least 6,000 hours of computer access, which is enough time to train 60 children to a vocational level of IT literacy.
"Buckingham Palace's unwanted IT equipment is now being used in disadvantaged schools in Chile, Ecuador and South Africa and by not-for-profit organisations working in the areas of agriculture and health in Colombia, India and Niger among others."
