Amager Bakke (Amager Hill) also known as Amager Slope is a waste-to-power incinerator plant under construction.

The plant is estimated to cost $670 million, is scheduled for construction to be completed in 2017, and is expected to burn 400,000 tons of waste annually. It was designed by Bjarke Ingels with a 85m tall sloped roof that doubles as a ski slope.[1][2] Technically, it is designed to change between operating modes, producing 0-63 MW electricity and 157-247 MW heat, depending on heat need and available wind. It produces more clean water than it uses.

A special feature of this facility will be that the chimney is intended to not emit its exhaust continuously, but instead in form of smoke rings.
