This solution will come in the form of readily designed and engineered liquefaction plant modules, which the companies claim will allow for lower pre-investment costs, accelerated implementation time, high predictability on project economics, and reduced overall capital costs.
Alterra’s technology is a thermochemical liquefaction process, which converts hard-to-recycle plastics into a liquid hydrocarbon product. This liquid intermediate product can then be further refined into high-quality raw materials for new plastics and chemicals.
As of today, Neste says that it has processed more than 6,000 tons of plastic-derived feeds, including ISCC PLUS certified oil from Alterra’s industrial-scale site in Akron, Ohio.
Alterra and Neste started collaborating on chemical recycling in 2021, while Alterra and Technip Energies began working on chemical recycling-related solutions in 2022.
