Neste has successfully commissioned its new upgrading facility for liquefied waste plastic (LWP) at its Porvoo refinery in Finland.
This €111 million investment marks a major milestone in the scale-up of chemical recycling, enabling the production of high-quality feedstock for the plastics and chemicals industry. With an annual capacity to process up to 150,000 tons of liquefied waste plastic, the facility is the world’s largest LWP upgrading facility, and processing will be gradually ramped up.
“The successful commissioning proves that we can process liquefied waste plastic at an industrial scale.
“This achievement demonstrates Neste's capability to develop advanced technology, set safety standards, and create new supply chains for challenging new raw materials.
“We are proud of this achievement, and I want to express my sincere thanks to our partners and employees whose dedication has allowed us to turn this vision into a reality,” said Jori Sahlsten, executive vice-president of oil products at Neste.
Neste has processed liquefied waste plastic (e.g. pyrolysis oil) since 2020.
The construction of the new upgrading facility and its integration to the existing oil refinery began in 2023 and was completed at the end of 2025.
Production ramp-up was commenced in 2026 and will advance gradually depending on market and legislation development.
The new facility allows Neste to close the quality gap between crude liquefied plastic waste and the high-quality drop-in raw materials required by the petrochemical industry.
“We enable the scale-up of chemical recycling by upgrading liquefied plastic waste.
“The plastic originates from low-quality waste streams not suitable for mechanical recycling and destined for incineration or landfills,” addedMaiju Helin, director of polymers and chemicals at Neste.
