COPENHAGEN, Oct. 4 (Xinhua) -- Copenhill, a new artificial ski slope built on the roof of a huge waste incinerator here, was opened to the public on Friday.

While the public can whizz down the 450-meter ski slope, up to 450,000 tonnes of waste will continue to be converted annually into heat and electricity in Amager Bakke Incinerator Plant underneath skiing guests' feet.

Architects from Bjarke Ingels Group (BIG), a group which designed Copenhill, said there will be no unpleasant smells either inside the factory or on the roof.

"It's a great example of what we call hedonistic sustainability. You drive up into a glass elevator where you can look into the factory at the same time," David Zahle, a partner at BIG, told building magazine Dagens Byggeri.

It provides an unconventional "clash" between experience and the fact that it is a working factory, Zahle added.

"We have the highest environmental standards. We have the highest energy efficiency. And we have the safest plant in the world," Jacob Simonsen, director of Amager Resource Center which runs the ski area, said in a press release.
