Denmark 🇩🇰

In Copenhagen, they approached the issue of resource use very rationally and made a two-in-one plant.

The Copenhell plant is the world's largest power plant capable of processing 440,000 tons of waste annually to generate electricity. 

In addition, it has been made a popular tourist attraction - in summer its winding roof turns into a green hiking trail where you can walk and run. And in winter, an artificial snow slope for skiers.

On its facade is the highest artificial climbing wall in the world.
