WP 1 aims to improve the sustainability of biobased PBS synthesis through an increase of its renewable carbon content, and by considering low energy consumption synthesis route (solid state polymerization). Another objective is the development of adapted grades of PBS for targeted applications (branched polymers, and copolymers).
- The first task will investigate the different routes to produce biobased 1-4 butanediol.
- The second task aims to produce different grades of PBS adapted to targeted applications.
- The third task will investigate an innovative sustainable route for PBS synthesis, the Solid State polymerisation.
- The last task aims to produce selected PBS grade and PBS copolymer grade.
WP 2 aims to provide both basic and innovative packaging for technical, economical and environmental evaluations. Classical flexible compounding and processing approaches will be used, but also an innovative barrier coating route will be tested and adapted to packaging barrier specifications.
The first task is dedicated to the adaptation of materials by compounding by three complementary technologies (foil extrusion-thermoforming, film blowing extrusion and injection moulding).
The second task aims at improving barrier properties by means of compounding and in line surface treatments.
The third task aims to develop active antimicrobial packaging.
WP 3 aims to assess mechanical, thermo-mechanical and transfer properties (permeabilities, aroma scalping and migrations) of PBS-based materials. The results will be used to develop recommendation guidelines for the safety assessment of PBS-based food packaging materials.
The first task consists in characterizing physical and food compatibility properties of PBS-based materials.
The second task relates to permeation properties to gas and water vapour of the packaging materials under standard and real-use conditions.
The third task focuses on the study of aroma scalping and transfer of flavour components.
The fourth task concerns the safety assessment of PBS processed materials, by identification of potential migrants, measurement and modelling of the transport coefficients.
The fifth task consists in developing recommendation guidelines for the safety assessment of PBS-based materials.
WP 4 aims to assess the performances of both the basic and the innovative packaging materials with active properties in extending the shelf-life of different food products produced by the SMEs of the Consortium. Packaging materials and conditions currently used by the SMEs will be used as controls. Experiments will be carried out at lab-scale level and then the results will be validated by the SMEs at pilot-scale level.
The aim of WP 5 is to provide data to WP6 in the case of two end life scenarios, from polymer to polymer, and from polymer to monomer.
The first task is dedicated to the development of the degradation level characterization methods using an intelligent chemical sensor for in situ monitoring.
Recycling scenario by remelting, restabilization, and chain extension will be tested in the second task. An alternative scenario appropriate for recycling complex polymer blends and copolymers will be tested in the last task.
WP 6 aims to reduce the environmental impacts by means of an optimized process design of new PBS based packaging materials. The overall outcome will combine in parallel the environmental aspects (by means of Life Cycle Assessment) and the economic aspects (by means of Life Cycle Costing).
WP 7 concerns demonstration activities, WP8 communication and knowledge transfer and WP9 management activities.
