Uppsala

The majority of the biofuel we use comes from forestry waste, such as branches, tops and bark.

In 2025, the remaining fossil oils in our energy mix will be replaced with bio-oils. This means that our district heating in Uppsala will be produced with fossil-free and recycled fuels. Recycled fuels comprise waste and wood that cannot or should not be recycled. Recycled wood may contain fossil residues, such as paint or impregnation, and the fossil content of waste is primarily plastic.

In Uppsala, we energy recycle waste from households and businesses that cannot be reused or recycled. This process uses energy that would otherwise be wasted, and is an important part of the city's circular economy. Using recycled energy reduces the need for new energy production and the amount of waste that ends up in landfill, thereby reducing greenhouse gas emissions.

In March 2022, Vattenfall's main heating plant, Boländerna, in Uppsala was supplemented with the biofuel plant, Carpe Futurum. This has reduced carbon dioxide emissions by around 200,000 tonnes per year, thereby halving the climate footprint of all Uppsala residents with district heating once peat was replaced with renewable, recycled biofuels.

Carpe Futurum has a heating capacity of 110 MWth and is an important part of a programme to transform heat production in Uppsala by phasing out fossil fuels. The plant can be fuelled with forest chips, recycled wood, and bark in various combinations. It can be operated with the three fuels individually or in different combinations, providing high flexibility.
