Neste has commissioned a EUR 111 million facility for upgrading liquefied waste plastic (LWP) at its Porvoo refinery in Finland. With an annual capacity of up to 150,000 tonnes, Neste describes it as the world’s largest facility of its kind.
The plant upgrades pyrolysis oils produced from hard-to-recycle plastic waste, including mixed, contaminated and multilayer plastics unsuitable for mechanical recycling. The upgraded material can be co-processed at the refinery and used as feedstock for plastics and chemicals.
Neste has processed liquefied plastic waste since 2020. Construction of the new unit started in 2023 and was completed in late 2025, with capacity being ramped up in 2026.
According to Neste, chemical recycling instead of waste incineration, combined with substitution of fossil feedstocks, can reduce virgin fossil resource use by more than 70% and greenhouse-gas emissions by more than 35%.
