Накратко на български

Биоразградимите полиестери се разработват така, че да имат по-добри свойства от пластмасите от полипропилен и полиетилен. Това помага за създаването на устойчиви опаковки, които са лесни за производство и управление след употреба.

Innovative designs to enable plastic packaging circular economy

Over the past century, plastics have become the material of choice for packaging because of their low cost, high performance, and easy processability, occupying an ever-expanding range of applications. Far from decreasing, their production is constantly increasing, and estimations indicate that by 2050, the production of plastic packaging could exceed 250 million metric tons. Although it was envisioned since a couple of decades that polyesters such as poly(lactide) (PLA) or poly(3-hydroxybutyrate) (P3HB) could be part of the solution thanks to their renewable origins (e.g. starch, cellulose, and bacteria) and biodegradability, the inferior properties of these materials compared to most of synthetic plastics currently used in the packaging industry (mainly polypropylene (PP), polyethylene (PE) and poly(ethylene terephthalate) (PET)) have considerably limited their insertion in the plastic market. NATURE-EID is an innovative research training program at the forefront of the circular economy of biobased polyesters for packaging applications. The project offers to develop new synthetic routes for novel biobased polyesters where a material is not only designed based on its performance and low cost but also considering the overall sustainability of the product, considering its sourcing, the use of green chemistry synthesis, the potential scalability of the production process, and the management of its end-of-life. To achieve this goal, 4 ESRs have been trained on organic chemistry, synthesis and analysis of polymers, recycling processes, and sustainable chemical processing: Flore Kilens (ESR 1), Claire Morand (ESR 2), Gabriella Garbonova (ESR 3) and Bige Bati (ESR 4).

Цел на проекта

Plastics are the material of choice in packaging applications because of their low cost, high performance and ready processability. Such is their success that it is expected that by 2050 the production of plastic packaging will exceed 250 million metric tons. Considering most plastics that are employed in the packaging industry are used for less than a week, the lack of environmental degradability has led to a tremendous growth of disposed plastics. This growth, together with the fact that the vast majority of synthetic plastics are designed for performance and durability and not for degradability and recyclability, has brought tons of plastic accumulation in the oceans and landfills - ~56 million tons per year. The problem has been highlighted by the acclaimed prediction that by 2050, the ocean is expected to contain more plastics than fish (by weight). Although it was envisioned that biodegradable polymers based on ester linkages such as poly(lactide) (PLA) or poly(3-hydroxybutyrate) could be part of the solution because they are mainly derived from biorenewable sources (e.g. starch and cellulose) and can be enzymatically or hydrolytically degraded leading to an environmentally closed circular ecosystem, the low permeability in the case of PLLA and the poor mechanical properties in the case of PHB has limited their potential. NATURE-EID proposes an innovative research training program at the forefront of circular economy of biobased polyesters. In particular, the project will develop fundamental knowledge in the synthesis of new biobased polymeric materials where the polymers are not only design based on their performance but also on their recyclability.
