The overall aim of the CIRCforBIO project proposal is to achieve high GHG emission savings from the substitution of fossil fuels with advanced biofuels as well as to promote the realization of the circular economy concept for biomass. This will be achieved through (i) the implementation and demonstration of an innovative biorefinery concept for the production of bioethanol, used oil (raw material for biodiesel) and other bioproducts from biomass produced from household, catering (restaurants, cafeterias and bakeries) and industrial food waste and from agricultural residues and (ii) the creation of an interactive platform for facilitating the realisation of the circular economy concept for 2nd generation biomass in Greece.
