VTTI and Connex move forward with the development of the Greenstock Pretreatment Facility in Amsterdam

Rotterdam, the Netherlands: December 10^th, 2025.

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 tons 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.

United for a more sustainable future

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 decarbonization 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 commented: “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.”

Progress Details: What FEED is about

The previous phase focused on defining the technical scope and capabilities, and validating them through technical due diligence, including proof-of-concept testing at laboratory and pilot scale. The FEED phase marks a critical milestone in the progression toward construction and commissioning. During this phase, the project team will develop the basic engineering of the assets, further refining the facility’s technical design, equipment specifications, and construction strategy, ensuring that Greenstock Pretreatment Facility is engineered for safety, efficiency, and long-term sustainability.

The project combines Connex’s expertise in renewable feedstock sourcing and in-depth understanding of the feedstock supply market needs coupled with VTTI’s extensive operational excellence and strong service mindset in energy infrastructure, logistics, and storage. Together, these ensure a scalable, flexible, and future-proof solution for the growing demand for sustainable feedstock pretreatment in Europe.

Next Steps

During the FEED phase we will focus on working closely with local authorities, partnering with world class technology providers and engineering companies, securing contracts with customers and ensuring we comply with all the environmental requirements to make the facility a responsible and well-regulated part of the regional industrial landscape.
