In Copenhagen, Denmark lies Amager Bakke, a unique power plant. Not only is it the world's cleanest waste-to-energy facility, it's also home to a man-made mountain called CopenHill with its own ski slope, the world's tallest climbing wall and challenging hiking trails up the building where you'll find the best views of Copenhagen.
Opened in October 2019, the building was designed by Bjarke Ingels Group with an aim to create a building that can "contribute positively to the city, become part of the city, and even to be a landmark of the capital". The plant serves 680,000 people and takes waste from up to 300 lorries each day. Its steam turbine produces 63MWh of energy, while its heat exchangers are used in a district heating system.
