Extrusion Foaming of Bioplastics for Lightweight Structure in Food Packaging
EXTRUSION FOAMING OF BIOPLASTICS FOR LIGHTWEIGHT STRUCTURE IN FOOD PACKAGING A thesis submitted for the degree of Doctor of Philosophy by Sitthi Duangphet School of Engineering and Design Brunel University December 2012 i Abstract This thesis reports the systematic approaches to overcome the key drawbacks of the pure PHBV, namely low crystallisation rate, tensile strength, ductility, melt viscosity, thermal stability and high materials cost. The physical, mechanical, thermal, and rheological properties of the pure PHBV were studied systematically first to lay a solid foundation for formulation development. The influence of blending with other biopolymers, inclusion of filler, and chain extender additives in terms of mechanical properties, rheology, thermal decomposition and crystallization kinetics were then followed. Creating lightweight structures by foaming is considered to be one of the effective ways to reduce material consumption, hence the reduction of density and morphology of PHBV-based foams using extrusion foaming technique were studied comprehensively in terms of extrusion conditions (temperature profiles, screw speed and material feeding rate) and the blowing agent content. The material cost reduction was achieved by adding low-cost filler (e.g. CaCO3) and reduction of density by foaming. The thermal instability was enhanced by incorporation of chain extender (e.g. Joncryl) and blending with a high thermal stability biopolymer (e.g. PBAT). The polymer blend also improved the ductility. Adding nucleation agent enhanced the crystallization rate to reduce stickiness of extruded sheet. The final formulation (PHBV/PBAT/CaCO3 composite) was successfully extruded into high quality sheet and thermoformed to produce prototype trays in an industrial scale trial. The effect of the extrusion conditions (temperature profiles, screw speed and material feeding rate) and the blowing agent content are correlated to the density reduction of the foams. -
The Nature of Hellenistic Domestic Sculpture in Its Cultural and Spatial Contexts
THE NATURE OF HELLENISTIC DOMESTIC SCULPTURE IN ITS CULTURAL AND SPATIAL CONTEXTS DISSERTATION Presented in Partial Fulfillment of the Requirements for The Degree of Doctor of Philosophy in the Graduate School of The Ohio State University By Craig I. Hardiman, B.Comm., B.A., M.A. ***** The Ohio State University 2005 Dissertation Committee: Approved by Dr. Mark D. Fullerton, Advisor Dr. Timothy J. McNiven _______________________________ Advisor Dr. Stephen V. Tracy Graduate Program in the History of Art Copyright by Craig I. Hardiman 2005 ABSTRACT This dissertation marks the first synthetic and contextual analysis of domestic sculpture for the whole of the Hellenistic period (323 BCE – 31 BCE). Prior to this study, Hellenistic domestic sculpture had been examined from a broadly literary perspective or had been the focus of smaller regional or site-specific studies. Rather than taking any one approach, this dissertation examines both the literary testimonia and the material record in order to develop as full a picture as possible for the location, function and meaning(s) of these pieces. The study begins with a reconsideration of the literary evidence. The testimonia deal chiefly with the residences of the Hellenistic kings and their conspicuous displays of wealth in the most public rooms in the home, namely courtyards and dining rooms. Following this, the material evidence from the Greek mainland and Asia Minor is considered. The general evidence supports the literary testimonia’s location for these sculptures. In addition, several individual examples offer insights into the sophistication of domestic decorative programs among the Greeks, something usually associated with the Romans. -

Biodegradable Packaging Materials from Animal Processing Co-Products and Wastes: an Overview
polymers Review Biodegradable Packaging Materials from Animal Processing Co-Products and Wastes: An Overview Diako Khodaei, Carlos Álvarez and Anne Maria Mullen * Department of Food Quality and Sensory Science, Teagasc Food Research Centre, Ashtown, Dublin, Ireland; [email protected] (D.K.); [email protected] (C.Á.) * Correspondence: [email protected]; Tel.: +353-(1)-8059521 Abstract: Biodegradable polymers are non-toxic, environmentally friendly biopolymers with con- siderable mechanical and barrier properties that can be degraded in industrial or home composting conditions. These biopolymers can be generated from sustainable natural sources or from the agri- cultural and animal processing co-products and wastes. Animals processing co-products are low value, underutilized, non-meat components that are generally generated from meat processing or slaughterhouse such as hide, blood, some offal etc. These are often converted into low-value products such as animal feed or in some cases disposed of as waste. Collagen, gelatin, keratin, myofibrillar proteins, and chitosan are the major value-added biopolymers obtained from the processing of animal’s products. While these have many applications in food and pharmaceutical industries, a sig- nificant amount is underutilized and therefore hold potential for use in the generation of bioplastics. This review summarizes the research progress on the utilization of meat processing co-products to fabricate biodegradable polymers with the main focus on food industry applications. In addition, the factors affecting the application of biodegradable polymers in the packaging sector, their current industrial status, and regulations are also discussed.
