Decarbonisation technology proven at Waste-to-Energy plant


Danish researchers have demonstrated that it is possible to remove most of the carbon dioxide (CO2) from the emissions of a waste incinerator, and by demonstrating the viability of the process, the researchers believe that they have developed a key technology in the fight against climate change. A pilot plant has been operational in Copenhagen for several months and a novel gas monitoring technology has enabled the optimization of plant efficiency.

If global leaders are to deliver on their commitments to achieve net zero, one of their key objectives will be to develop and exploit decarbonisation technologies such as carbon capture and storage (CCS) and carbon capture, utilisation and storage (CCUS). Researchers from the Technical University of Denmark (DTU) are therefore working with a highly innovative waste incineration plant in Copenhagen to develop a process that is able to capture carbon dioxide (CO2) from its emissions. The project is utilising advanced gas analyzers from measurement product manufacturer Vaisala to measure carbon capture efficiency and therefore CCUS viability. 

The researchers have developed a pilot plant to remove CO2 from the emissions of the incinerator at the Amager Bakke Waste-to-Energy Plant, which is one of the largest combined heat and power (CHP) plants in northern Europe, with the capacity to treat 560,000 tonnes of waste annually. Developed by the Copenhagen-based waste management company ARC (Amager Ressourcecenter), which is jointly owned by five Copenhagen-area municipalities, the CHP plant features a number of innovations including a rooftop artificial ski slope, which is part of an outdoor activity centre known as CopenHill.
