Amager Bakke: Climate-Friendly Energy Plant

The ‘Amager Bakke’ is one of the largest Climate-Friendly Waste-To-Energy plant situated at Copenhagen, Denmark. The name Amager Bakke is a combination of the name of a place in named Amager in Denmark and Bakke means Hill in the Danish language. The construction of this complex is serving combined heat and power generation application. Apart from one of the largest waste-to-energy plants in entire northern Europe, Amager Bakke complex also performing part as an environmental education centre. Amager Resource Centre (Amager for branding), the Copenhagen-based waste management company has developed this project. Amager Resource centre has owned by five different companies named Dragor, Frederiksberg, Hvidovre, Copenhagen, and Tranby to execute this project.

The total estimated value of this innovative project is €470m ($611m). This unique construction has the latest waste treatment technology for superior efficiency & better environmental performance. A feature like Skiing on its roof offers recreational facilities for a city residence. The construction of this project started in March 2013 and completed in 2017. But it was inaugurated in October 2019.

Amager Bakke: Energy From Waste

The layout of the Amager Bakke plant contains the main two furnace lines. These lines further connected to the boiler along with a generator and steam turbine system. Each fuel line can burn 35 tons of waste in an hour. Initially, the cranes lift the entire organic waste and fed them to a double lane combustor through the hopper. Amager Bakke has ‘Babcock & Wilcox’ type boiler as well as advanced combustor grate. These grates are known as Dynagrate. It looks similar to the staircase. The grate bars are arranged alternately and mounted on a shaft for optimizing the agitation of the fuel bed. The Dynagrate has the capacity to burn any kind of waste, even metals. Its unique mechanical design has a specific mechanism that restricts the contact of these tubes with each other. This feature brings down the maintenance cost of the furnace.

In order to optimize the heat generation, this plant utilizes the flue as condensation technology. It also uses the Selective Catalytic Reduction System to decrease NOx emission. Apart from this, The ESP (Electrostatic precipitator) also helps to catch the particle in flue gases. Amager Bakker plant restraints 100 Megaton of Carbon dioxide emission every year. Besides this, it allows the while Copenhagen to reuse the metal waste. In addition to this, the condensation of flue gas help to recuperate around 100 million litres of water and reuse 100 Megaton of ash as road-building material.

Amager Bakke: Energizing Cities

Fundamentally Amager Bakke is “Waste-to-Energy” plant, which generates energy by burning the waste from more than 45000 companies & 700,000 residence in Copenhagen, Denmark. The plant runs with the highest efficiency of 107% with 100% utilization of energy. However, this plant gives 25% more energy output than the old one. Compared to the conventional plants, Amager Bakke produces steam at a tremendous temperature of 440 Celsius with 70 bar pressure. Almost two times the performance compared to the old plant. Within just 2 hours the waste in oven burns out at a temperature of 1,100° C. The Amager Hill Plant can produce 0.8 MWh of electricity form each ton of resource waste burning.

Till day, this plant has produced more than 1,200,000 MWh of energy by burning more than 440 Megaton of wastage. Amager Bakke produces electricity and heat energy enough for district heating satisfying the demands of their needed consumers. With diverse technology, Amager Bakke redirects all the steam to the turbines. On the contrary, to fulfil the requirement of district heat steam is steered directly towards heat exchangers as well as supports wind and solar energy.

Amager Bakke: Climate-Friendly Approach of Energy Plant

Amager Bakke has recognized as a Climate-Friendly waste heat power plant around the world. It has revolutionary smoke cleansing technology. Unlike other power plants, Amager Bakke does not release exhaust fumes directly into an atmosphere containing toxic and greenhouse gases. Each furnace has a separate ‘Smoke Purification System’. This system consists of dust filter, electric filter, scrubbers and catalysts to remove NOx gases from the smoke. The scrubbers perform tasks of removing mercury, hydrochloric acid, sulfur dioxide, and water vapour from exhaust fumes. At the end of this process, Wet dust filter removes, any remaining specks of dust.

A typical measuring station continuously registers the pollutants in exhaust flue gases at the end of the chimney. This station ensures and maintains environmental safety parameters. Parent organization ARC, which has developed and running Amager Bakke is also planning to absorb 500,000 tons of CO2 from the atmosphere with its ‘ClimAid Copenhagen’ Project. The idea is to make the Amager Bakke zero carbon footprint & Climate-Friendly Energy Plant. The absorption of this much CO2 is as equal to 95% of annual emission by Amager Bakke.

Amager Bakke: Sustainability & Urbanization

The Amager Bakke project aims to encourage technological and architectural development as well as environmental sustainability. Amager Bakke is an excellent example of harmony between urbanization and sustainability. The Copen hill’s rooftop is designed in a downward direction. It attracts tourists with its unique and state of art level design. There are many more amenities on Copen Hill like a running path, a skiing slope, and a grove of trees, and a café. There is an artificial climbing wall of 80 m which is the tallest artificial wall in the world. By all means, this is one of the technology other countries around the world must adapt; as an approach to become a Climate-Friendly nation. Idea & technologies like Amager Bakke will promisingly lead the world to the “Zero Carbon Emission” environment.
