Hafslund Celsio

Frontier facilitated offtake agreements with Hafslund Celsio, Norway’s largest supplier of district heating and owner/operator of Norway’s largest waste incineration plant in the outskirts of the capital, Oslo. This offtake enables the first-ever carbon removal retrofit of a waste-to-energy facility. Frontier buyers will pay $31.6 million to remove 100,000 tons of CO₂ between 2029 and 2030. Hafslund Celsio’s facility in Oslo processes around 350,000 metric tons of sorted residual waste each year. The facility incinerates this waste, and the excess energy is used to produce electricity and heat.
