The Shareholders' Newsletter #77 Summer 2025

Objective:

Produce biofuel from waste and residues (animal fat, used cooking oil) that, mixed with JET A-1 (kerosene), will be marketed in the form of sustainable aviation fuel (SAF) for our retail and professional customers in the aviation sector.

Missions :

• Collect feedstock from circular sources, ensuring their sustainability, traceability and quality, and their compliance with cost criteria. Prioritize local, then national, and then European sources, so as to secure them.
• Ensure production flows from supply through to the shipment of finished products while complying with security, quality and health standards. The main steps in biofuel production at the various production units are as follows:
  
  • > Pretreatment, to remove any impurities, such as gums, that could clog up facilities, as well as phosphorus and metals, which are major sources of corrosion
  • > Hydrotreatment, to transform oil into biofuel by breaking down the structures of the oil molecules and forming linear molecule chains
  • > Isomerization, to break down the long chains of molecules that determine the waxing point and put them together differently, in small branches
  • > Separation of products according to their waxing point: -47° for aviation fuel, which must not solidify at extreme temperatures at altitude (from -8° to -16° the biofuel is intended for the road fuel market)
