Available in PDF, EPUB and Kindle. Book excerpt: Nowadays, we are witnessing highly dynamic research activities related to the intriguing field of biodegradable materials with plastic-like properties. These activities are stimulated by the strengthened public awareness of prevailing ecological issues connected to growing piles of plastic waste and increasing greenhouse gas emissions; this goes hand-in-hand with the ongoing depletion of fossil feedstocks, which are traditionally used to produce full carbon backbone polymers. Polyhydroxyalkanoate (PHA) biopolyesters, a family of plastic-like materials with versatile material properties, are increasing considered to be a future-oriented solution for diminishing these concerns. PHA production is based on renewable resources and occurs in a bio-mediated fashion through the action of living organisms. If accomplished in an optimized way, PHA production and the entire PHA lifecycle are embedded into nature´s closed cycles of carbon. Sustainable and efficient PHA production requires understanding and improvement of all the individual process steps. Holistic improvement of PHA production, applicable on an industrially relevant scale, calls for, inter alia, consolidated knowledge about the enzymatic and genetic particularities of PHA-accumulating organisms, an in-depth understanding of the kinetics of the bioprocess, the selection of appropriate inexpensive fermentation feedstocks, tailoring of PHA composition at the level of its monomeric constituents, optimized biotechnological engineering, and novel strategies for PHA recovery from biomass characterized by low energy and chemical requirements. This Special Issue represents a comprehensive compilation of articles in which these individual aspects have been addressed by globally recognized experts.

Download or read book Current Advances in Biopolymer Processing and Characterization written by Martin Koller and published by . This book was released on 2017 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book presents current R&D activities to unravel the physico-chemical properties of diverse biopolymers, and their processing towards functionalised, high-performance bio-products with defined applications. The importance of this research becomes obvious by considering the annual plastic production of about 330 Mt, the lion's share thereof based on the conversion of fossil feedstocks that is highly recalcitrant against biodegradation. Alternative environmentally degradable plastics cover not even 5% of today's plastic market. Such biopolymers encompass various macromolecules of biological origin with diverse monomeric composition, and manifold physico-chemical properties. This structural diversity makes them potential candidates to produce bulk materials, e.g., for packaging purposes, smart functionalised materials in special niches like the biomedical field. Consequently, we witness an increasing trend towards new natural polymers to replace well-established products like plastics. After decades of global R&D developments in this field, and numerous body blows on the way to the anticipated market breakthrough of biopolymers, it is generally recognised that the success of such new materials needs progress in both material performance and production prices. The book Current Advances in Biopolymer Processing & Characterisation is dedicated to the current state-of-the-art of production, modification, characterisation, and processing of two major biopolymer groups: Firstly, polysaccharides, nature's most abundant raw materials, are represented by specialised contributions on biomedical applications of starch and its follow-up products. Polysaccharides were also studied for the examples of functionalised thermoplastic starch, molecular and hydrocolloidal characteristics of xanthan in aqueous environments, and by the design of functionalised xylan-based bio-materials. Secondly, the second series of contributions encompasses diverse biopolyesters. Advanced methods to improve the properties of PLA, fine-tune PLA properties by triggering PLA's crystallisation rate during melt processing, and the strongly emerging field of 3D-printing of PLA, PCL, and microbial PHA are described. Finally, the authors familiarise the reader with the application of mixed microbial cultures to produce PHA heteropolyesters with different thermo-mechanical properties in dependence on cultivation strategy and the microbial species composition. This compilation of new biomaterials with surprising functions and performance, based on these natural polymers will address scientists active in biopolymers production, functionalisation, characterisation, and processing towards bio-technomers. The book is also dedicated to undergraduate students of polymer chemistry and polymer processing, and to representatives of the polymer industry who are interested in developing innovative, sustainable and smart polymeric products. Activities motivated by reading this book shall boost the impatiently desired market penetration of biopolymers and their follow-up products. Such materials definitely display a socioeconomic impact by addressing prevailing ecological concerns such as depleting fossil resources, growing piles of plastic waste, and increasing global warming. The contributions to this book illustrate that bio-inspired remedies for prevalent ecological problems are already available, developed by experts in polymer sciences and engineering, or that these solutions are at least in the status of development.

Available in PDF, EPUB and Kindle. Book excerpt: Towards more sustainable packaging with biodegradable materials! The combination of the continuously increasing food packaging waste with the non-biodegradable nature of the plastic materials that have a big slice of the packaging market makes it necessary to move towards sustainable packaging for the benefit of the environment and human health. Sustainable packaging is the type of packaging that can provide to food the necessary protection conditions, but at the same type is biodegradable and can be disposed as organic waste to the landfills in order to biodegrade through a natural procedure. In this way, sustainable packaging becomes part of the circular economy. ?Sustainable Food Packaging Technology? deals with packaging solutions that use engineered biopolymers or biocomposites that have suitable physicochemical properties for food contact and protection and originate both from renewable or non-renewable resources, but in both cases are compostable or edible. Modified paper and cardboard with increased protective properties towards food while keeping their compostability are presented as well. The book also covers natural components that can make the packaging functional, e.g., by providing active protection to the food indicating food spoilage. * Addresses urgent problems: food packaging creates a lot of hard-to-recycle waste - this book puts forward more sustainable solutions using biodegradable materials * State-of-the-art: ?Sustainable Food Packaging Technology? provides knowledge on new developments in functional packaging * From lab to large-scale applications: expert authors report on the technology aspects of sustainable packaging
