16. Effects of plasticizing and crosslinking on the mechanical and barrier properties of coatings based on blends of starch and poly(vinyl alcohol)
Abstract : In the last decades, intensive research has been carried out in order to replace oil-based polymers with bio-based polymers due to growing environmental concerns. So far, most of the barrier materials used in food packaging are petroleum-based materials. READ MORE

17. Plasticized Poly (lactic acid) Films - Preparation and Properties
Abstract : The development of biodegradable polymers from renewable resources is of importance in order to prevent the depletion of fossil fuels and the increasing emissions of carbon dioxide to the atmosphere caused by the commodity plastics of today. However, to be able to replace these non-environmentally friendly materials, production costs of biodegradable polymers have to be decreased and their physical properties need to be enhanced.

18. Agro-Waste Derived Additives for Polylactide and Tapioca Starch
Abstract : Development of materials from renewable resources is one of the big challenges facing our world. In this thesis agro-industrial waste derivatives were developed and evaluated as additives for two common renewable polymer matrices, polylactide (PLA) and starch. Two waste products, wood flour (WF) and rice bran (RB) were evaluated in different forms. READ MORE

19. Material Properties of Starch and Cereal Protein Films and Foams
Abstract : Materials that are renewable and biodegradable are demanded for environmental reasons. Biopolymeric materials, such as materials from starch and cereal proteins, are both renewable and biodegradable. However, starch and cereal protein materials are generally rather brittle and therefore need to be plasticized to become more flexible. READ MORE

20. Processing and properties of nanocomposites based on polylactic acid, chitin and cellulose
Abstract : The production of bio-based and biodegradable nanocomposites has gained attention during recent years for environmental reasons; however, the large-scale production of these nanocomposites still poses challenges. The objective of this work has been to prepare bio-based and biodegradable nanocomposites via liquid-assisted extrusion and to gain a deeper understanding of the process and the relationship between the process, composition, structure and properties.
