People looking for fun in the city of Copenhagen, in Denmark, can head to a new attraction, known as CopenHill. There, they can ski or snowboard down a special snowless slope, explore hiking trails, or scale a dizzying 20-story climbing wall.
But there’s more to this artificial mountain. Beneath the slope is a waste-to-energy plant. The facility burns the city’s garbage to make electricity and heat. That keeps the trash out of landfills.
Peter Madsen Nordestgaard is an engineer who helped build the facility. He hopes other cities will build similar multiuse structures. “I hope this will be a milestone,” he says.
