The BIOCODE project aims to develop high-value extraction compounds (e.g. protein, oil, waxes, and carotenoids), cellulose and hemicellulose products (nanocelluloses, soluble cellulosic macromolecules, sugars and lactic acid) and lignin based materials (biochar, soil additives, chemicals) from main commercial grain crop residues (corn, rapeseed and wheat co-streams). A sequential fractionation concept based on extraction pre-treatment (fractionation of minor components) followed by hydrothermal destructuration (fractionation of major components) will be developed and integrated with a variety of conversion techniques.

The main objective of the ValBio3D project is to develop sustainable and 100% biobased composites based on agroindustrial residues, addressing the bioeconomy of the future. Sub Goals: 1. Develop novel routes for production of a bioplastic based on agroindustrial residues 2. Develop processes for production of sustainable nanofibres suitable as reinforcement of bioplastics in structured biocomposites and as a main component in bioapplications 3. Develop novel routes for functionalizing nanofibres and bioplastic for optimal adhesion in the biocompounds 4. Develop prototype biocomposites based on 3D (bio)printing as a novel technology 5. Perform a lifecycleassessment (LCA) of biocomposites

There is a trend in packaging industry toward more sustainable packaging materials not interfering with the end-of-life or recovery schemes and helping to avoid plastic waste accumulation. Simultaneously, there is interest in bio-based materials, which could open up possibilities for various biopolymers. Single-layer biopolymer films rarely have a competitive edge against synthetic films, thus combining several individual layers or films into multilayer packaging materials becomes necessary. In this way, good properties of several materials can be combined and, for example, the overall barrier properties may be improved.

With the aim of achieving a more sustainable world, a number of efforts are currently oriented to replace synthetic polymer with the use of natural analogues, in order to obtain different materials. The objective of this project is to study in detail the characteristics of complexes formed by two different natural polyelectrolytes, such as chitosan and xylan. The research plan includes the study of the effect of the order of polyelectrolyte addition, relation of charge between them as well as the impact of the ionic strength and pH of the media in the external charge of the resulting complex. By reaching a better understanding of the condition of formation of these complexes, it is expected to widen the possibility of use of recycled, unbleached fibres in applications such as the manufacture of high quality packaging papers, and on the other hand, to manufacture films with excellent mechanical properties, of potential use in food packaging.
