BioBarr concerns the development of new bio-based and biodegradable food packaging materials by enhancing barrier functionalities to the biopolymer PHAs (polyhydroxyalkanoates) and by validating the new material in the food industry environment. PHAs is potential substitute for conventional polymers, since they possess similar properties; respect to polylactic acid (the most widespread biobased/biodegradable material), PHAs show higher biodegradability and better functional properties and mechanical strength. However, applications of PHAs as food packaging materials are subjected to some limitations. PHA shows medium values of O2 and H2O transmittance while many the most critical factors for some foods (such dry products as bakeries) in relation to packaging are moisture uptake leading to loss of crispiness and oxidation of fats. For overcoming this limiting factor in PHA food applications, BioBarr aims to enhance PHA vapour and gas barrier properties through material functionalization. In the first research line, the approach consists of the use of biodegradable materials with adequate properties to be compounded in multi-layer structures specific for the food product category to be packed, in order to optimize functional properties. The innovation consists of laminating PHA with PLA (polylactic acid). The second challenging research line in BioBarr is surface treatments (nanoform metallization with AlOx or SiOx or metallization Aluminum process) of PHA films. New materials will be validated on a restricted number of food products in the sector of bakery, representative of different shelf-life requirements and duration, with the purpose to increase shelf-life at least by 10%. Final impact will be the creation of a new biobased value chain. Proposal takes into account the needs and the growth opportunities of actors operating in each value chain step: bioplastic producer, extrusion and filming actors, converter, inks producers, food industries end-users

The high-performance requirements requested by the industry and consumers are responsible that currently 17% of total plastic packaging is multilayer material , meaning 3.03 Mt of plastics. Difficulties for recycling it are accentuated, being mostly landfilled or incinerated. MERLIN project has joined a partnership between sorting technology providers, recyclers, research centers, social innovation experts and end-users to design cradle to cradle solutions. This 36-month research project will offer innovative solutions for all the processes required to increase the quality and rate of recycled plastic materials coming from multi-layer packaging waste: (i) SORTING (combining optical sensors, Artificial Intelligence (A.I.) and robotics), (ii) DELAMINATION (optimizing depolymerisation and using solvent-based processes), (iii) RECYLING (techniques for repolymerization and upcycling of polymers) and (iv) VALIDATION (developing rigid and flexible packaging solutions and demonstrating circularity of the processes). These solutions will be developed and later validated in a real environment to reach technology readiness level (TRL) 6. This will be complemented with additional techniques and tools for circularity design to increase knowledge and effectiveness in the closure of the European multilayer plastic chain. Finally, transversal activities related to regulation and standardization, safety, sustainability, business, training, dissemination and communication will support to maximize the impact and effectiveness of the project. These actions are aligned with the ones proposed by the European Plastic Strategy to achieve that by 2030 all plastic packaging should be designed to be recyclable or reusable and decrease the quantity of waste generated Potential annual carbon footprint saving that could be achieved recycling all the multilayer waste in Europe could reach 7.42 Mt CO2/year, with a potential economic of €10,605 million and more 106,000 new job positions.
