Available in PDF, EPUB and Kindle. Book excerpt: Since the early 1970s the subject of biodegradable plastics has acquired a rapidly growing literature of academic research papers. It has also acquired a formidable volume of patent documentation and all this has been over whelmed by an astonishing quantity of serious media and political com ment. A new entrant into any technical arena w. ould, in most technologies, simply visit their technical library and pick up a text book on the subject in the expectation of absorbing the basic facts before launching into the daily task of updating and evaluating. Scientific conferences have produced many substantial volumes carrying the word 'biodegradable' on their covers, and there has even been a specialist monograph on the topic of bacterially produced polymers but, surprisingly, no book has yet emerged providing a general survey of the subject. Having devoted half my pro fessional career to the subject of biodegradable plastics I agreed to take on the editorial job of producing such a book when asked by the publisher. I knew that the task of finding expert specialists and persuading them to contribute dispassionate accounts of their specialisms would not be easy, but the difficulties that I have encountered were far greater than I expected. Some were simply too busy, others were involved in patent disputes or commercial negotiations. In giving an account of the work that I and my students carried out at BruneI University I believe that I have written in a manner that displays enthusiasm without prejudice.

Download or read book Degradable Polymers written by G. Scott and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: Few scientific developments in recent years have captured the popular imagination like the subject of'biodegradable' plastics. The reasons for this are complex and lie deep in the human subconscious. Discarded plastics are an intrusion on the sea shore and in the countryside. The fact that nature's litter abounds in the sea and on land is acceptable because it is biodegradable - even though it may take many years to be bioassimilated into the ecosystem. Plastics litter is not seen to be biodegradable and is aesthetically unacceptable because it does not blend into the natural environment. To the environmentally aware but often scientifically naive, biodegradation is seen to be the ecologically acceptable solution to the problem of plastic packaging waste and litter and some packaging manufacturers have exploited the 'green' consumer with exaggerated claims to 'environmentally friendly' biodegradable packaging materials. The principles underlying environmental degradation are not understood even by some manufacturers of 'biodegradable' materials and the claims made for them have been categorized as 'deceptive' by USA legislative authorities. This has set back the acceptance of plastics with controlled biodegradability as part of the overall waste and litter control strategy. At the opposite end of the commercial spectrum, the polymer manufactur ing industries, through their trade associations, have been at pains to discount the role of degradable materials in waste and litter management. This negative campaign has concentrated on the supposed incompatibility of degradable plastics with aspects of waste management strategy, notably materials recycling.
Download or read book Biorelated Polymers written by Emo Chiellini and published by Springer Science & Business Media. This book was released on 2001-10-31 with total page 420 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book includes papers on polymeric materials from renewable resources known as `Biorelated Polymers and Plastics', and issues are bound to their utilization and environmental impact in their production, conversions to manufacts and ultimate disposal of post-costume manufacts. Modern industrial developments inspired by the new concepts of sustainability and ecocompatibility require a deeper attention to renewable resources as a new-old source of raw material and feedback. This new trend, occurring not only in industrialized countries but also in emerging countries and countries in transition, thoroughly permeates the polymer and plastic industry, due to the big impact that those materials have on the modern way of life. Plastic waste, specifically that stemming from segments of packaging, containers for solids and liquids and single use items, is attracting much effort from municipality officers, producers and converters, aimed at finding a harmonized solution among the various options available for their appropriate management. In this respect, polymeric materials of natural origin (biopolymers), as well as materials from renewable resources useable for the production of monomeric precursors, or semi-synthetic polymeric materials, constitute a focal point for future industrial development in the production of polymers and plastics. The present book contains much valuable information and scientific hints on a modern approach aimed at designing processes and products with minimal negative environmental impact.
Download or read book Degradable Polymers written by G. Scott and published by Springer Science & Business Media. This book was released on 2002 with total page 500 pages. Available in PDF, EPUB and Kindle. Book excerpt: The emphasis in degradable polymers has changed since the first edition of this book. Biomedical and agricultural applications remain important topics of scientific and commercial interest in the second edition. However, an increased emphasis on composting as a means of recovering value from wastes has led to a new impetus to understand how plastics degrade in the environment and the implication of this for international standards. Polymers based on renewable resources are also a major topic in this edition but the debate continues about their long-term sustainability and ecological advantages over degradable man-made polymers. Degradable Polymers will be of interest not only to academic and industrial scientists working on packaging, agricultural and medical applications of plastics but also to students of environmental science and legislators concerned with the effects of man-made materials in the environment.

The introduction chapter is followed by a description of the general characteristics of biodegradable polymers and pathways of their degradation in the human body. Particular pitfalls and specifics of their various biomedical and pharmaceutical applications, especially in the field of pharmaceutical technology, are described in order to define the ideal carrier polymer system for specific types of therapy. Finally, the work presents the classification of these polymers based on the type of degradation mechanism. This section also includes the chemical structure of particular polymer molecules, their chemical or bio-synthesis and the description of their uses in specific biomedical and pharmaceutical applications. The book could be used as a textbook for students of medical and pharmaceutical sciences as well as by researchers in this field or industrial area. In the past few decades, biodegradable polymers have reached significant importance in fields of biomedical and pharmaceutical applications. They have become preferred candidates for the manufacture of therapeutic forms, for instance, orthopaedics devices, temporary bone screws and spins, three-dimensional scaffolds for tissue engineering or drug delivery systems for sustained and targeted release. Each of these applications requires material with specific physical, biological, and chemical properties, as well as specific degradation profile. These polymers (natural or synthetic) undergo hydrolytic or enzymatic degradation, which both have some advantages and disadvantages. Most widely used polymer materials in biomedical applications are listed, including their structure and degradation pathways.
