Transforming waste into energy

Millions of tonnes of combustible waste are disposed of in European landfills every year. This poses a significant environmental problem, as these materials release methane when they break down. Methane is one of the most potent greenhouse gases, with a greenhouse effect 25 times greater than CO₂.

From waste to resource

Instead of being sent to landfill, waste can be treated to recover energy. Waste that cannot be reduced, reused, or recycled is converted into district heating and electricity. Capturing and using the heat from waste incineration helps reduce climate impact and supports a more circular economy. 

After energy recovery, metals and salts can be extracted from the ash and slag, ensuring that even residual materials contribute to resource efficiency.

In Sweden, around 6.2 million tonnes of waste are recycled each year, providing approximately 30% of the country’s district heating and 2 TWh of electricity. Thanks to extensive district heating networks, Swedish plants are well equipped to process waste from other European countries for energy recovery. Around 2 million tonnes of waste are imported annually, helping to avoid landfill and reduce emissions.
