We advised Neste as it signed a EUR 250 million 10-year loan with NIB. The loan will finance Neste’s investments related to research and development (R&D) in processing lower-quality feedstocks into high-quality renewable products; as well as the liquefied waste plastics (LWP) investment at Neste’s refinery in Porvoo, Finland. The R&D activities supported by the loan focus on the development of renewable solutions. These include, for example, expanding feedstock capabilities and technologies that enable the processing of new and lower-quality waste and residues into high-quality renewable end products. Part of the financing supports Neste’s liquefied waste plastics investment in Porvoo, related to upgrading low-quality plastic waste into high-quality feedstock at an industrial scale. The investment contributes to advancing circular economy solutions by enabling the use of hard-to-recycle plastic waste as a replacement for virgin fossil raw materials. The unit has an annual capacity to process up to 150,000 tonnes of liquefied waste plastic. Production ramp-up commenced in 2026.

We acted as Finnish law legal adviser to the lenders and the export credit agencies in connection with the EUR 514.4 million green project financing for the development and construction of Easpring Finland New Materials Oy’s cathode active material (CAM) manufacturing plant in Kotka, Finland. The borrower, Easpring Finland New Materials Oy, is a joint venture owned by Beijing Easpring Material Technology, Finnish Minerals Group and LG Energy Solution. The financing was provided by six international commercial banks, with Société Générale acting as financial adviser and mandated lead arranger together with Natixis as co-mandated lead arranger, and DNB, ICBC, ING and Standard Chartered participating as lenders, with support from the export credit agencies Finnvera and Sinosure. The project represents a significant milestone for Finland and the European battery value chain by strengthening Europe’s domestic supply of cathode active materials, a key component in lithium-ion batteries for electric vehicles and energy storage applications. Once the first phase of the project is operational, the Kotka facility is expected to produce approximately 60,000 tonnes of cathode active material annually, making it one of the largest CAM production plants in Europe and supplying leading battery manufacturers across Europe.
