Something
out of Nothing

Meliora Bio is based in Kalundborg and upcycles biomass to new and innovative products. Through our work, we show a way forward within sustainable production and positive impact for consumers and environment.

Who We Are

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. After years of inactivity, the plant is being brought back to life to produce advanced, second-generation bioethanol and innovative food ingredients.
