Croatia and also is a stakeholder for projects in France and the US. Downstream, Axens is deploying its Jetanol suite of technologies for the production of sustainable aviation fuels (SAF) from bio- ethylene, with several commercial projects under development in the US and Japan. Furthermore, the company is currently working to develop new applications and products of this type by leveraging low-carbon ethanol and heavier alcohols. The BioButterfly project meanwhile aims to produce renewable butadiene from low-carbon ethanol, used, among other things, in the manufacturing of synthetic rubber, a key raw material in the industry. Exploring the potential to convert heavier alcohols Going forward, Axens plans to continue its strategic shift into bio-sourced olefins of all types, notably by moving from ethylene into heavier alcohols. Building upon the expertise and know-how gained through its development of ethylene applications, the company aims to prepare the way for significant industrial capacities for producing bio-olefins from heavier alcohols. Though the market for these alcohols is smaller today, the technology offers many potential applications that can have a big impact

in the future. For example, Axens is currently working to produce SAF by adapting Atol for processing heavier alcohols. Since compounds such as butanol also play a major role in today’s industrial economy, bio- based solutions for their production stand to play a vital role in decarbonising these industries and their applications. Alternative solution for ethylene production The global production capacity of ethylene grew from 150 million tonnes (MT) in 2017 to 214 MT in 2021 (Statista, 2023), making it the most widely produced olefin intermediate in the world (Noah Chemicals, 2017). Atol enables the production of bio-ethylene with improved yields from a variety of renewable feedstocks. The technology reduces energy consumption and provides a commercially viable alternative to obtaining ethylene from fossil fuels or food- based ethanol.
