The Porvoo investment, expected to be completed in 2025, follows last year’s completion of a major cracker furnace update at Borealis’ site in Stenungsund, Sweden.

The steam cracker in Porvoo has a nameplate capacity of 430 kt/y ethylene and 263 kt/y propylene. With the investment, three of the ten cracker furnaces in the olefins unit will be modified to enable a total annual production of 120 kt of base chemicals based on renewable and recycled feedstocks.

"With a focus on reinventing essentials for sustainable living, our €4.5 million investment in our steam cracker in Porvoo moves us closer towards a future of circular economy transformation. Through strategic furnace modifications and a commitment to renewable and chemically recycled base chemicals, we are poised to elevate annual production to 120 kilotons, forging a path of environmental stewardship and economic resilience," said Wolfram Krenn, Borealis executive vice president Operations and Base Chemicals.
