Integrating waste-to-energy in Copenhagen, Denmark

Completed in 2017, the new Amager Bakke waste-to-energy project in Copenhagen, Denmark, is the largest of its kind in the Nordic countries. Its revolutionary design, including ski slopes on the roof and climbing walls, helps to integrate the facility with the city. As explained in this paper, the plant also has ultra-high energy efficiency and environmental performance, which required innovative solutions. Achievements include combined heat and power production with a net thermal efficiency of 107% and air emissions generally below 10% of limit values. Recovery of over 200 000 t of condensate a year could also replace other water resources, such as district heating water and make-up water.
