Dossier – Bioplastics as food contact materials
1 Definition of bioplastics The two main groups of bioplastics are biobased polymers and biodegradable plastics. Biobased polymers are derived from biomass sources, which are not necessarily biodegradable. Biodegradable plastics, on the other hand, can be either made of natural or fossil sources. In 2012, the IUPAC recommended a terminology for biorelated polymers [1, 2]. Two further, special c...
متن کاملProcess Design and Evaluation of Biobased Polyhydroxyalkanoates (PHA) Production
Conventional plastic products are made of crude oil components through polymerization. Aim of the project ANIMPOL is to convert lipids into polyhydroxyalkanoates (PHA) which constitute a group of biobased and biodegradable polyesters. Replacing fossil based plastics with biobased alternatives can help reducing dependence on crude oil and decrease greenhouse gas emissions. As substrate material ...
متن کاملSynthesis and Verification of Biobased Terephthalic Acid from Furfural
Exploiting biomass as an alternative to petrochemicals for the production of commodity plastics is vitally important if we are to become a more sustainable society. Here, we report a synthetic route for the production of terephthalic acid (TPA), the monomer of the widely used thermoplastic polymer poly(ethylene terephthalate) (PET), from the biomass-derived starting material furfural. Biobased ...
متن کاملMagic Mountains and Multi-disciplines in International Medical Mobilities; Comment on “Patient Mobility in the Global Marketplace: A Multidisciplinary Perspective”
Medical mobilities offer both opportunities and challenges. This tension follows the same ratio as many other historic fora, but offers at the same time a sustainable equilibrium. Multi-disciplines are, therefore, the key to the medical lifeworld for the global health and well-being of transnational health users around the globe.
متن کاملPhoto-autotrophic Production of Poly(hydroxyalkanoates) in Cyanobacteria
Replacing conventional by biodegradable plastics is claimed to be beneficial for the environment, especially when the drastic negative consequences of litter are considered. Such plastics are called biobased if the basic chemicals derive from organisms, preferably from autotrophic organisms, such as higher plants, algae or cyanobacteria.1 Established biotechnological processes convert carbohydr...
