The EcoXtract consortium overcame significant technical difficulties to lay the foundations of a new business called EcoXNew dedicated to bringing 2-methyloxolane to the market as EcoXtract. EcoXnew is led by the chief engineer in Pennakem. It started on 1 May 2024, the day after the EcoXtract project ended. The confidence of investors that this business represents is a major outcome of the project and provides the major pathway to impact for the project’s achievements.
The consortium has significantly advanced the EcoXtract technology. The consortium overcame very significant difficulties from the pandemic (material shortages, inflation, obtaining services) to start testing as scheduled. The tests enabled the production of the first oil and soybean meals in a plant originally designed for hexane. The feed meals obtained have been successfully tested for animal feed. They can replace hexane extracted meals and they reduce or eliminate the transfer of hexane residues in milk and butter. But longer runs revealed difficulties due to the precipitation of solids in the oil/solvent mixture earlier than in the classical hexane process. The technical testing programme was extended complemented by the Solids Working Group supported by close interaction with engineering companies. The management of these solids will require further process optimisation to ensure stables and long term runs without clogging.
The commercial potential of EcoXtract for extracting oilseeds has been clarified. Agriprotein and DeWit together led work to identify ways forward for the use of EcoXtract in both high volume processing for food and feed and for speciality oils. Drawing on the technical investigations, and working closely with a global leader in oilseed processing technology, the consortium has generated comprehensive engineering guidance for both value chain types. Parallel to this, a business plan for an entry-level commodity processing plant has been developed.
EcoXtract is now approved as a food and feed processing aid. The consortium has clearly established that EcoXtract is a safe solvent for use in the food and feed industry. Its normal use presents no toxicological risk to consumers and livestock. This option to replace hexane represents a very significant step forward for food and feed safety.
EcoXtract can contribute to a carbon neutral world. The project’s lifecycle assessment of EcoXtract compared with hexane reveals that the conversion of biomass co-products into 2- methyloxolane is relatively energy demanding. However, the solvent itself is carbon neutral and this characteristic means its relative environmental performance improves as energy systems are decarbonised. Along with decarbonisation of energy, this will enable carbon neutrality in oilseed processing.
Practical experience and engineering studies confirm that EcoXtract is a step forward for work-place safety. The practical conversion of the NHE plant and the engineering plans highlight the work-place safety of EcoXtract.
