Technology Brief	Meliora Bio ApS, together with the bioengineering company COMET, upcycles crop residues from wheat straw that is collected from local farmers to produce second-generation bioethanol, prebiotic dietary fibers, and lignin. The biorefinery aims to have the lowest possible CO2 footprint, with minimum use of energy and water, while reducing its production waste to zero. This circular approach also benefits local farmers by fully utilizing their whole harvest, while also generating a valuable new revenue stream and improving the circularity of the food chain. Valmet’s Bio Trac pretreatment process is a core technology in the state-of-the-art biorefinery that transforms the wheat straw residues to second-generation bioethanol. As a byproduct, the process also produces C5-sugar, which COMET utilize to make ARRABINA, a prebiotic fiber that is added in different foods to promote better gastrointestinal health.
Additional Information	Meliora Bio is a modern state of the art biorefinery upcycling straw for bioethanol, prebiotics, and lignin. The refinery was built by Ørsted in 2009, and since 2020 it has been a part of Karsten Ree Holding. Under the current ownership, the plant has seen very significant reconstruction and expansion to meet demands and ambitions for continuous innovation.
