Greenstock Pretreatment Facility

Introduction to the Pretreatment Process
The pretreatment process is designed to upgrade a wide range of complex waste oils and fats into refined feedstocks suitable for advanced biofuel production. It applies a sequence of thermal, mechanical and chemical treatment steps that remove impurities, improve quality parameters and achieve consistent specifications required by downstream renewable fuel facilities.The process begins with pre-purification, where bulk contaminants are separated and the feedstock is conditioned for further treatment. It then proceeds through drying to remove moisture, adsorption to capture polar and non-polar contaminants, and filtration to eliminate solids and residual impurities. A final deacidification step reduces free fatty acids and improves overall stability.Through this integrated sequence, the process significantly reduces chlorides, metals, nitrogen, sulphur, phosphorus, and other critical contaminants. It enables the handling of a broad spectrum of challenging feedstocks while delivering high-quality treated material that meets the requirements for sustainable fuel pathways such as HVO, SAF, and co-processing applications.



Stakeholders
Greenstock Pretreatment Facility is a joint venture of VTTI and Connex.Both parties are combining their expertise to develop an innovative pretreatment facility, offering the upgrade of quality waste and residues into sustainable feedstocks, with on-site blending and storage at VTTI Amsterdam (ETA).Connex brings years of proficiency in sourcing and trading feedstocks and end-products, complemented by VTTI?s successful experience in storage, blending, and intricate logistics operations. Together, they form an extraordinary alliance, supporting the energy transition with unmatched synergy and efficiency.Both VTTI and Connex are on a mission to accelerate the energy transition towards mitigating greenhouse gas emissions in the industry.

Align with Chakir what role will P66 have from a commercial point of view. Phillips 66 Phillips 66 P.O. Box 421959 Houston, TX 77242-1959 Great Britain https://www.phillips66.com/emerging-energy/ Their business case: Lower-carbon fuels like renewable diesel, sustainable aviation fuel (SAF) and renewable naphtha are a natural extension of Phillips 66’s current business and allow us to build on core adjacencies to become a market leader.  Currently producing ~50,000 BPD of renewable fuels at our  Rodeo Renewable Energy Complex  and co-processing variety of renewable feedstocks at our Humber facility in U.K. Our Commercial organization has active positions in renewable feedstock sourcing and product placement. Additionally, we are pursuing opportunities in circular plastic economy, such as co-processing.

Business Case
Product is typically expected from outside of the EU and will be pretreated at VTTI premises to later be:Exported to UKHome consumption in EU (potentially Spain)
