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

Only in the EU, we generate every year around 89M tonnes of Food Loss and Waste (FLW), accounting for 20% of the total food produced, with costs estimated at ?143 Bn, impacting each stage of the Food Value Chain. In SISTERS, we propose a set of systemic innovations addressed to reduce FLW generated in every stage of the Food Value Chain in Europe that will solve main existing challenges in Production, Processing, Marketing (retailing/wholesaling), Consumption, and the Logistics among stages. SISTERS will design the 1st European Short Chain Platform for farmers to sell their discarded production, favouring local economies, providing access to nutritious and healthy food to the less favoured consumers. Smart and reusable food containers will be designed to diminish food losses during transportation, maintain bulk and packed food in ideal conditions with new accurate sensors allowing immediate reaction. Moreover, to improve the preservation and quality of food a set of bio-based and home-compostable packaging solutions will be created reducing their potential negative impacts in the environment. A novel SISTERS Seal of Excellence will promote sustainable practices among retailers. While the information provided to the consumers with QR and dynamic labelling incorporated in the packaging is expected to impact on retailers and consumers sustainable awareness, thus reducing the discard of food and associated FW. With these cross-sectorial innovations, we will achieve an ambitious environmental & economic impact of the current dynamics in the food system, contributing to the reduction of FLW and to change the unsustainable consumer behaviours. With the support of the EC, SISTERS will be a key EU project addressing the problem in a holistic way, reducing FLW by 27.4% and CO2 emissions by around 20% in the case studies. Our interdisciplinary SISTERS consortium consists of 18 partners from 8 European countries, with wide expertise in fighting FLW from Farm
