CARBAFIN will develop, based on an integrated biocatalytic production technology, a radically new value chain for the utilisation of surplus sucrose, estimated to exceed 300 kilotons/year as of 2019, from sugar beet biomass in the EU. CARBAFIN will demonstrate bio-based co-production of a functional glucoside and fructose. The glucoside products of CARBAFIN have large-scale uses in nutrition and feed, cosmetics and detergents (≥ 100 kilotons/year). Fructose is exploited in the production of 5-hydroxymethylfurfural (HMF), a versatile chemical building block currently considered for making bio-based plastics. Leading platform technologies in biocatalytic cell factories and downstream processing, conjointly optimised in CARBAFIN for performance efficiency and cost-effectiveness under full integration of LCA and economic evaluation, are key to make industrial co-production of glycosides and HMF via fructose competitive in today's markets (≤ 5 € production costs/kg). In addition, CARBAFIN contributes to the establishment of new, fully renewables-based value chains across the European industries, linking the sugar industry sector to the cosmetics, chemicals, polymer and detergents sectors and strengthening the sugar industries' role in food and feed. It supports the efficient cascading use of sugar beet-derived sucrose in combination with biomass-derived base chemicals (e.g. glycerol, glucose). CARBAFIN's HMF production aims at replacing petroleum-based chemicals with bio-based building blocks. CARBAFIN will thus contribute to development of a chemical industry that is low-carbon, resource-efficient and sustainable. CARBAFIN will help Europe to maintain global leadership in industrial biotechnology and secure position as innovation leader in sugar-based products. CARBAFIN's innovations will involve broadly the engagement of societal actors with particular emphasis on consumer awareness and acceptance.
