Biopolymers from Renewable Resources is a compilation of information on the diverse and useful polymers derived from agricultural, animal, and microbial sources. The volume provides insight into the diversity of polymers obtained directly from, or derived from, renewable resources. The beneficial aspects of utilizing polymers from renewable resources, when considering synthesis, pro cessing, disposal, biodegradability, and overall material life-cycle issues, suggests that this will continue to be an important and growing area of interest. The individual chapters provide information on synthesis, processing and properties for a variety of polyamides, polysaccharides, polyesters and polyphenols. The reader will have a single volume that provides a resource from which to gain initial insights into this diverse field and from which key references and contacts can be drawn. Aspects of biology, biotechnology, polymer synthesis, polymer processing and engineering, mechanical properties and biophysics are addressed to varying degrees for the specific biopolymers. The volume can be used as a reference book or as a teaching text. At the more practical level, the range of important materials derived from renewable resources is both extensive and impressive. Gels, additives, fibers, coatings and films are generated from a variety of the biopolymers reviewed in this volume. These polymers are used in commodity materials in our everyday lives, as well as in specialty products.

The progressive dwindling of fossil resources, coupled with the drastic increase in oil prices, have sparked a feverish activity in search of alternatives based on renewable resources for the production of energy. Given the predominance of petroleum- and carbon-based chemistry for the manufacture of organic chemical commodities, a similar preoccupation has recently generated numerous initiatives aimed at replacing these fossil sources with renewable counterparts. In particular, major efforts are being conducted in the field of polymer science and technology to prepare macromolecular materials based on renewable resources. The concept of the bio-refinery, viz. the rational exploitation of the vegetable biomass in terms of the separation of its components and their utilisation as such, or after suitable chemical modifications, is thus gaining momentum and considerable financial backing from both the public and private sectors. This collection of chapters, each one written by internationally recognised experts in the corresponding field, covers in a comprehensive fashion all the major aspects related to the synthesis, characterization and properties of macromolecular materials prepared using renewable resources as such, or after appropriate modifications. Thus, monomers such as terpenes and furans, oligomers like rosin and tannins, and polymers ranging from cellulose to proteins and including macromolecules synthesized by microbes, are discussed with the purpose of showing the extraordinary variety of materials that can be prepared from their intelligent exploitation. Particular emphasis has been placed on recent advances and imminent perspectives, given the incessantly growing interest that this area is experiencing in both the scientific and technological realms. Discusses bio-refining with explicit application to materials Replete with examples of applications of the concept of sustainable development Presents an impressive variety of novel macromolecular materials

This book shows how the use of biodegradable plastics in agriculture can have a profound positive impact on plasticulture. Starting with an organic chemistry approach to biodegradable and compostable plastics, both natural and synthetic, it then analyzes the technological and agronomic aspects of existing bioplastics for protected cultivation (mulching, direct cover, low tunnels). It describes the new sprayable biodegradable mulching method, which is based on the use of waterborne polysaccharides and cellulosic fibers. A further chapter describes the research and technology of biodegradable plastics for different agricultural practices. It also includes chapters on life cycle assessment (LCA) of biodegradable plastics for agriculture, and existing and developing standards in the field. It is a valuable resource for agronomists, chemical and materials engineers, polymer technologists and scientists, as well as for a more general readership interested in the application of green chemistry principles to the vast world of crop production. Mario Malinconico is Research Director at the Institute of Polymers, Composites and Biomaterials, National Research Council, Italy. /p

Nature learned long ago how useful proteins are as a diverse set of building blocks to make materials with very diverse properties. Spider webs, egg whites, hair follicles, and skeletal muscles are all largely protein. This book provides a glimpse into both nature's strategies for the design and produc tion of protein-based materials, and how scientists have been able to go beyond the constraints of natural materials to produce synthetic analogs with potentially wider ranges of properties. The work presented is very much the beginning of the story. Only recently has there been much progress in obtaining a molecular understanding of some of nature's com plex materials, and the mimicry or replacement of these by synthetic or genetically engineered variants is a field still in its infancy. Yet this book will serve as a useful introduction for those wishing to get started in what is sure to be an active and productive field throughout the 21st century. The authors represent a wide range of interests and expertise, and the topics chosen are comprehensive. Charles R. Cantor Center for Advanced Biotechnology Boston University Series Preface The properties of materials depend on the nature of the macromolecules, small molecules and inorganic components and the interfaces and interac tions between them. Polymer chemistry and physics, and inorganic phase structure and density are major factors that influence the performance of materials.

Today's petrochemical industry is an amazing model of production efficiency, taking crude oil and supplying thousands of discrete chemicals and materials from just seven primary building blocks. Renewable raw materials offer a new set of primary building blocks including carbohydrates in the form of cellulose, starch, homicellulose, and monomeric sugars, aromatics in the form of lignin, hydrocarbons in the form of fatty acids and polyols in the form of glycerol. Yet chemical production today is overwhelmingly dominated by crude oil, principally because conversion technology for renewables still lags far behind that available for nonrenewables. Technology is needed that will lead to renewables based chemical processes that rival or exceed the diversity and efficiency of today's chemical industry. The cellulose and Renewable Materials division (CELL) of American Chemical Society offered a forum for this topic Feedstocks for the Future: Renewables for the production of Chemical and Materials, at the national ACS meeting in Anaheim, CA, March 28-April 1, 2004. This symposium included discussions of emerging conversion technologies for renewable building blocks, new mechanistic understanding of these conversion processes, development of new catalytic processes tailored for renewables, life cycle and process analysis for renewables, and identification of new structures that could serve as platforms for renewables-based product families. The book is intended to have a strong emphasis on organic chemistry, mechanism, and structure, and novel synthesis and production of chemicals, polymers and materials. More specifically, the reader will find information in the following areas: 1) new transformations of carbohydrates to chemicals and polymers 2) novel oleochemical processes; new uses of glycerol and fatty acids 3) transition metal catalyzed transformations of carbohydrates, lignin, fatty acids, glycerol, etc. 4) economic, environmental, and life cycle analysis of chemicals derived from renewables 5) production of new polymeric materials from renewables 6) new biocatalytic transformations of renewable building blocks 7) industrial uses of renewables and renewables based building blocks
