Ensuring sustainable food systems requires vastly reducing its environmental and health costs while making healthy and sustainable food affordable to all. In current food systems many of the costs of harmful foods and benefits of healthful foods are externalized, i.e. are not reflected in market prices and therefore not in decision making of actors in food value chains. Solving the externality problems means to determine current costs of externalities and redefine food prices (true pricing) to internalize them in daily practice. Policy makers, businesses and other actors in the food system, lack sufficient information and knowledge to internalize externalities to achieve a sustainable food system. FOODCoST responds to this challenge by designing a roadmap for effective and sustainable strategies to assess and internalise food externalities. FOODCoST provides approaches and databases to measure and value positive and negative externalities, proposing a game-changing and harmonised approach to calculate the value of climate, biodiversity, environmental, social and health externalities along the food value chain based on economic cost principles. FOODCoST provides an analytical toolbox to experiment, analyse, and navigate the internalisation of externalities through policies and business strategies providing tools and guidance to policy makers and businesses to assess the sustainability impact of their internalisation actions. FOODCoST emphasises the diversity of challenges of true pricing in different value chains and countries and regions, and cocreates, tests and validates the valuation and internalisation approaches in 11 diverse case studies enabling to test, validate and enrich the approaches in order to transit towards a sustainable food system. The project will be based on a multi-actor approach that will ensure a continuous dialogue with all relevant actors across the whole food system (land and sea).

Polymers, because of their properties and ease of processing into complex shapes are among the most important materials available to us today and the polymer industry makes a major contribution to the UK economy (18 billion per year). An exciting new family of materials are polymer nanocomposites (NCs), in which particles with nanoscale dimensions are dispersed in the polymer. The benefits of NCs derive primarily from the exceptionally large amounts of particle surface area that can be achieved for a small addition of particles (e.g. 5% by weight). Thus they offer dramatic improvement in material performance with significant increases in mechanical and gas barrier properties. The user of such a material therefore gets a more effective product (or one containing less material for the same effectiveness). It is well recognised that the nanoparticle-polymer interface/chemistry is a critical parameter in determining the degree of dispersion of particles in a nanocomposite and that the interfacial properties have a significant influence on nanocomposite performance. In recent times, however it has become apparent that the processing route by which the nanoparticle-polymer mixture is formed into a final product is an equally important aspect of NC manufacture and this is the area on which we will focus in this proposal.The principal aim of the proposed project is therefore to achieve a fundamental understanding of the interactions between material formulation, processing and properties of polymer nanocomposites and to apply this to the development of proof of concept applications which provide generic processing information for industry and academia alike. The work will include statistically designed experimental studies using pilot scale polymer processing equipment and validation trials on industrial scale equipment. Parameters to be studied include extruder shear and temperature profiles, screw design, additives such as anti-oxidant, post extrusion deformation such as biaxial extension and cooling rates. We will characterise the materials in terms of structure, mechanical, thermal and barrier performance in order to link process to structure and structure to performance.We will utilise the combined processing, characterisation and analytical skills and facilities existing in Queen's University Belfast (QUB) and the University of Bradford (UoB), partners who have worked together successfully on large collaborative projects, in the past and currently, and have an excellent national and international track record in polymer processing research.

PRESERVE aims at boosting the circular use of bio-based packaging. To shift from the current situation (fossil-based, limited recycling), we build on award-winning upcycling strategies from past and on-going projects. We will enhance the performance of primary food packaging via bio-based barrier coatings for bioplastic and paper/board substrates, as well as via eBeam irradiation and microfibrillar-reinforcement. From the biotechnological side, we will leverage the compounding of enzymes in bioplastics to stimulate biodegradation, the enzymatic recovery of functional oligomers and the delamination of multilayer packaging via enzymatic detergents to enable their layer separation and recycling. The processes required to produce at least 10 packaging demonstrators will be upscaled. The enhanced bio-packaging will be validated with different types of food and drinks. Recovered biopolymers will be upcycled in added value applications such as packaging for personal care products and reusable carrier packaging (using textiles and composites). The versatility of our end of life options, materials, flexible and rigid packaging types and compatibility with different processes, ensure that PRESERVE results are relevant to more than 60% of the plastic packaging on the market, which long term substitution potential will be maximised thanks to the participation of several leading companies in the consortium. Our 2030 roadmap will outline the pathways to significantly influence the emergence of bio-based packaging and create jobs and growth in the sector. To widen PRESERVE impact, we will also perform life cycle and safety assessments, user acceptance studies and contribute to standardisation and certification. All in all, by contributing to the EU Plastics Strategy in a circular economy, our PRESERVE circular renewably sourced packaging solutions and derived upcycled applications will not only optimally preserve the food and drink but also our environment and its finite resources
