Pretreatment and upgrading of liquefied waste plastic play an important role in Neste’s approach to chemical recycling. These processes allow the company to increase flexibility for processing lower-quality plastic waste and scale up processing the liquefied waste plastic into high-quality petrochemical feedstock in its existing refinery in Porvoo.

“We have developed our capability to process circular raw material at the Porvoo refinery over the recent years and are now set to build a respective facility. The new facility processing 150 000 t of liquefied waste plastic, is planned to be finalised in 1H25,” states Markku Korvenranta, Executive Vice President in Neste’s Oil Products.

The project will see Neste building new assets at the Porvoo refinery, but also leveraging existing assets through retrofitting, to scale up chemical recycling fast and efficiently. The upgraded liquefied waste plastic will then be processed in the conventional refinery in which it will replace a portion of the fossil resources processed at the Porvoo refinery.

Required preparation works at the Porvoo refinery were successfully completed during 1H23, enabling the construction work to commence without any delay.
