Capturing Fossil and Biogenic Carbon Dioxide at Filbornaverket.

At Filbornaverket, waste incineration generates two types of carbon dioxide: fossil CO₂ and biogenic CO₂. Fossil CO₂ is released when materials derived from fossil fuels, like plastics and synthetic textiles, are burned. Biogenic CO₂, on the other hand, comes from the incineration of organic materials such as food waste, paper, and wood.

The challenge is that both types of CO₂ are emitted during the combustion process. When waste is burned to produce electricity and district heating, the carbon stored in these materials is released into the atmosphere. This is where Carbon Capture and Storage (CCS) comes in.

At Filbornaverket, the CO₂ is captured directly from the flue gases before it has a chance to reach the atmosphere. This is done through an advanced chemical absorption process where the flue gases are led through a capture unit. Inside, they are exposed to a solvent that binds to the CO₂ molecules. The captured CO₂ is then separated, compressed, and prepared for permanent storage deep underground.

This process effectively eliminates carbon emissions from waste incineration, allowing Filbornaverket to produce climate-neutral district heating and electricity for Helsingborg.
