Oslo's main waste incineration plant, Klemetsrud, has this week embarked on a major new experiment to capture the carbon dioxide emitted from burning rubbish.
The five-month project, run by Norwegian oil services company Aker Solutions, began on Monday. It marks the first time anywhere in the world that carbon dioxide will be captured from a waste-to-energy plant.
The city-run Klemestrud incinerator burns household and industrial waste to generate heat for the residents of Oslo. It burns more than 310,000 tonnes of waste every year, emitting more than 300,000 tonnes of carbon dioxide - the equivalent of 0.6 per cent of Norway's man-made emissions.
The test CCS plant will feed rubbish fumes through a network of pipes to capture the CO2 at a rate equivalent to 2,000 tonnes a year until the end of April. The project is being funded by Gassnova, Norway's state enterprise for developing carbon capture and storage.
Oscar Graff, head of CCS at Aker Solutions, said he expects the experiment to capture up to 90 per cent of the CO2 emitted by the plant. "The tests will verify important operating parameters such as energy consumption, solvent degradation, losses and required solvent make-up," he said.
Valborg Lundegaard, head of Aker Solutions' engineering business, said the experiment was of "international importance".
"This is pioneering work with significant potential as the world focuses on finding ways to limit carbon emissions," he said in a statement. "We see potential in this market across the world."
If the experiment is successful, Aker Solutions said it could roll out its CO2 capture technology at waste-to-energy sites around the world. There are currently around 450 plants in Europe and about 700 globally, the firm said.
