The estimates were released at the first two of four community recycling events held in Sydney and Brisbane.

The company began a national recycling program in December 2004.

The events extracted 20 tons of equipment; part of a global 250 tons recycled over the last two years via more than 50 recycling events.

Dell A/NZ Managing Director Joe Kremer said that by offering the free recycling service, the company hoped to set an example.

"Industry, retailers, government and consumers all have a role to play in reducing e-waste and we have actively supported the move towards a national recycling scheme led by the Australian Information Industry Association," he said.
