The goal is to scale up processing capabilities for liquefied waste plastic by implementing proprietary technologies to pretreat and upgrade liquefied waste plastic and integrating the technologies into the refinery operations. The targeted pretreatment and upgrading capacity of this first step is 400,000 tons per year. This development would be a major step towards Neste’s target to process over 1 million tons of waste plastic per year from 2030 onwards.
To produce drop-in petrochemical feeds from liquefied waste plastic (e.g. pyrolysis oil), intermediate refining is needed to remove detrimental impurities as well as optimize the chemical composition of the material.
In 2021, Neste successfully concluded the first series of trial runs processing liquefied waste plastic in its Porvoo refinery. Additional trial runs with larger volumes will continue in the course of 2022. While unprocessed liquefied waste plastic is usable for trial-scale runs, continuous processing at industrial scale will require the pretreatment and upgrading step to remove impurities and unwanted components.
To develop and build up the capabilities at its Porvoo refinery, Neste will evaluate possible options for innovation funding and works together closely with local authorities supervising environmental aspects of the investment. Following the feasibility study, investment decision readiness is targeted for 2023 and the gradual implementation is expected to start in 2024.
