1.- To characterize and evaluate feasibility of corn, rapeseed and wheat costreams as feedstocks for the developed fractionation and valorization concept. 2.- To develop supercritical CO2 (ScCO2) extraction pretreatment to fractionate intermediate products (protein, oil, waxes, and carotenoids) from corn, rapeseed, and wheat costreams. 3.- To investigate cellulose, hemicellulose and lignin fractionation via hydrothermal destructuration and valorisation of hemicellulose sugars using a ermentation to L(+) lactic acid. 4.- To investigate conversion of fractionated cellulose to nanocelluloses, fibres and soluble macromolecules using deep eutectic solvent (DES). 5.- To develop hydrothermal carbonisation (HTC) of lignin fraction. 6.- To conduct holistic sustainability and cost evaluation of developed concept to enhance the productisation, commercialisation and market uptake of the concept.
