CARBAFIN will develop, based on an integrated biocatalytic production technology, a radically new value chain for the utilisation of surplus sucrose from sugar beet biomass in the EU. CARBAFIN will demonstrate bio-based co-production of a functional glucoside and fructose, which will be exploited in the production of 5-hydroxymethylfurfural (HMF), a versatile chemical building block currently considered for making bio-based plastics.
