Aqueous biphasic systems

Liquid-liquid systems formed by two water-soluble components dissolved in water, which above given concentrations form two phases.


Facility with integrated processes to convert biomass into energy, fuels, materials, and commodity and value-added chemicals.

Green chemistry

Concept addressing the design of chemical products and processes aiming at reduce or eliminate the use and generation of hazardous substances.

Ionic liquids

Low melting temperature salts, composed of organic cations and organic/inorganic anions.

Natural products

Compounds that can be obtained from biomass.

Solid-liquid extraction

Process in which a solvent is added to solid biomass samples in order to extract target compounds.

Definition of the Subject

Research on the extraction and separation of value-added products from biomass has been a hot topic in the framework of biorefinery aiming a sustainable conversion of biomass into chemicals, materials, energy, and fuels....
