AMSTERDAM, Netherlands - One of China's electronic maker has been seen by some as the greenest business in the world.

Computer maker Lenovo ranked in at the top spot of environmental group Greenpeace's latest quarterly ranking of global electronics manufacturers. Once at the bottom of the list, Lenovo now leads the way in recycling industrial waste and taking steps on controlling toxic content, Greenpeace said.

"Given the growing mountains of e-waste in China -- both imported and domestically generated -- it is heartening to see a Chinese company taking the lead, and assuming responsibility at least for its own branded waste," said Iza Kruszewska, Greenpeace International's toxics campaigner, adding that "the challenge for the industry now is to see who will actually place greener products on the market."

Lenovo bought out IBM's personal computer division in 2004.

Apple, meanwhile, was placed at the bottom of the list of 14 companies.
