LiYF, a clean-tech startup based in Switzerland, has reached Technology Readiness Level 6 (TRL 6) for its proprietary process that enhances second-generation (2G) bioethanol production. This patent-pending technology improves efficiency, lowers operational costs, and boosts ethanol yields, reported Biofuels International.
The company utilizes agricultural and forestry residues to produce high-purity, fuel-grade ethanol, supporting the demand for low-carbon fuels in road, aviation, and maritime transport.
LiYF’s process incorporates multiple innovations designed to improve sustainability and cost-effectiveness. Notably, it cuts feedstock costs by 70% through the use of agricultural waste. Its Ultrasonic Baffled Hydrothermal (UBH) Reactor reduces pretreatment energy requirements by up to 20% and minimizes the formation of fermentation-inhibiting compounds.
Additionally, the CCH Hydrolysis system slashes enzyme usage by as much as fivefold, while the passive LCS cooling system eliminates the need for compressors or water pumps, further lowering energy consumption.
Collectively, these advancements reduce total production costs by 20–30% compared to conventional 2G bioethanol processes. The performance of the system has been demonstrated through lab-scale prototypes at TRL 6.
“Our team has made significant strides in overcoming key technical and economic hurdles in second-generation bioethanol,” said LiYF CEO Hangama Wanner. “Reaching TRL 6 is a major milestone, and we’re now focused on developing our proprietary equipment and finalizing engineering designs for our pilot plant. We welcome partnerships with researchers, investors, and strategic collaborators to explore potential synergies.”
