December 10, 2025 [Tank Storage Magazine]- VTTI and Connex, partners in the development of Greenstock Pretreatment Facility (GPF) at VTTI’s terminal in Amsterdam (ETA), have announced that the project has entered the front-end engineering design (FEED) phase. This milestone marks a significant step toward the facility’s planned operational launch in 2029, reinforcing both companies shared commitment to accelerating the energy transition.

Once complete, Greenstock Pretreatment Facility will be capable of processing over 400,000 tonnes of renewable feedstocks annually, enabling the production of sustainable fuels, including renewable diesel (HVO) and sustainable aviation fuel (SAF) from both standalone and coprocessing units. The facility will provide customers in Europe with comprehensive aggregation, blending and pretreatment capabilities for waste and residue-based feedstocks, including animal fats category 1, 2 and 3, used cooking oil and advanced oils and fats.

Ignacio Leone, business development director of Connex, says: ‘Reaching the FEED stage strengthens Connex’s commitment to shaping the future of sustainable feedstocks in Europe. Together with VTTI, we are building the infrastructure needed to secure a reliable supply of high-quality SAF and HVO feedstocks and to support the industry’s decarbonisation efforts. This next phase brings us closer to making sustainable fuels the standard for today’s market and for future generations.’

Quinten van Dam Merrett, SVP VTTI Netherlands comments: ‘The next phase of Greenstock Pretreatment Facility marks an important step in VTTI’s long-term strategy to support the energy transition by developing infrastructure that is future-ready and customer-focused. In partnership with Connex, we are expanding Europe’s access to sustainable feedstocks and enabling the growth of low-carbon fuels. The facility will reinforce Amsterdam’s role as a hub for sustainable fuels and demonstrate how we are integrating innovative technologies across our terminals to advance decarbonisation.’
