This book provides up-to-date results and information about compostable polymer materials in a coherent and comprehensive manner. It covers the entire spectrum of preparation, properties, degradation, and environmental issues. The emphasis is on recent studies concerning compostability and ecotoxicological assessment of polymer materials - important issues from the ecological point of view. Moreover, the thermal behaviour of compostable polymers is described. Their price evolution over the last decade, an estimation of the market and future perspectives are presented.
