Materials 7. Chemical, structural, biological, physical and mechanical characterization of the PHAs that are produced.. 8. Preparation of blends and composites of PHAs with selected polymeric materials including synthetic analogues of PHA, inorganic and/or organic fillers such as nanofillers. The organic fillers also include renewable agro-waste (lignocelluloses, polysaccharides and surplus crops), either directly or after appropriate physical or chemical modification. 9. Engineering design of PHA production and extraction unit operations combined with the analysis of the cost efficiency of the industrial process as found in the down-stream processing of slaughterhouses, rendering and biodiesel factories. 10. A key factor for the success of the project, i.e. its cost efficiency for industrial scale production of PHAs, is assessed in terms of the costs of raw materials, chemicals and energy required for the production of PHAs and its blends. 11. Assessment of eco-compatibility with evaluation of biodegradability under different environmental conditions of the obtained PHA formulations, as well as of some selected prototype items based on relevant blends and composites. Validation of the eco-compatibility of selected items is assessed by means of LCA and ecotoxicity tests. 12. Assessment of the biocompatibility of some selected PHA formulations and relevant items processed by means of in vitro cell toxicity and genotoxicity tests in respect of their potential value-added applications in food, packaging and biomedical fields. 13. The utilization of novel bioplastics, as attainable by means of environmentally sound processes based on waste from renewable resources as the raw material, for environmentally friendly plastic materials, meeting the EC directive 62/94 and the subsequent national regulations, constitutes the ultimate goal of the project.

This should finally facilitate the decision of responsible policymakers from waste-generating industrial sectors and from the polymer industry to break new ground in sustainable production. In future, PHA production from animal-derived waste should be integrated into existing process lines of biodiesel companies, where the raw material directly accrues. This can be considered as a viable strategy to minimize production costs by taking profit of synergistic effects. Info: 28 bioplastics MAGAZINE [05/12] Vol. 7
