The issue of biodamages comprises a wide range of scientific and practical tasks associated with protection of raw materials and products against damage by bacteria, fungi, insects and rodents during long-term storage, production, transportation and operation. The biodegradation is used for degradation and utilization of worn-out materials and articles. This research is urgent for ecology and the struggle against environmental contamination. The biodamage problem is both scientifically complex and practically diverse. Scientifically, it is based on the knowledge of material science, biology and chemistry.The first objective of this book is to provide detailed information on the three interrelated parts: bacteria and fungi (the source of biodamages); insects and rodents (materials and products depredators); and materials and products damaged by living organisms. The most modern data on morphology and physiology of biodegrading microorganisms are presented. The second objective of this book is to provide the reader with a systematisation of biological degradation on both natural and synthetic materials and products (plastics, textile, fibres, leather and fur, wood and so on). Problems of utilisation of polymeric wastes using microorganisms are discussed and main protection methods and technology for raw materials and semi-products against biodamages are shown. Practical recommendation for struggle against biodamage of materials by insects (moth, leather beetles, wood-fretters, cockroaches and termites) and rodents (mice and rats) are given.Since 1960 the biodamage problem received the official status as a large international and practical direction at the junction of sciences and practice of mankind and pooling efforts of various specialists. The final objective of this book is to illustrate that the problem of biodamages is very real today because it is relevant to many aspects of our everyday lives.This volume is intended to be a practical guide on biodamage and biodegradation of polymeric materials and a quick reference to students and researchers from academia and the industry.

Synthetic and semi-synthetic polymeric materials were originally developed for their durability and resistance to all forms of degradation including biodegradation. Such materials are currently widely accepted because of their ease of processability and amenability to provide a large variety of cost effective items that help to enhance the comfort and quality of life in the modern industrial society. However, this widespread utilization of plastics has contributed to a serious plastic waste burden, and the expectation for the 21st century is for an increased demand for polymeric material. This volume focuses on a more rational utilization of resources in the fabrication, consumption and disposal of plastic items, specifically: -Environmentally Degradable Polymeric Materials (EDPs); -Water-soluble/Swellable Biodegradable Polymers; -EDPs from Renewable Resources; -Biopolymers; -Bioresorbable Materials for Biomedical Applications; -Biorelated Polymers; -Standards and Regulations on EDPs.

In this report the factors which influence biodegradation are first explained. Methods of testing and evaluating biodegradation are then described and compared. The principles, relative costs and practical applications of specific tests are outlined together with the position with respect to recognised standards. The range of biodegradable polymers and polymer blends is then described, including natural and synthetic products. An additional indexed section containing several hundred abstracts from the Rapra Polymer Library database provides useful references for further reading.

As environmental performance becomes increasingly important, the development of man-made polymers and their associated benefits has been overshadowed by problems relating to their ultimate disposal. In the light of wider acceptance of polymers for use in high technology applications, Polymers and the Environment aims to redress the balance. The book reviews the properties and industrial applications of polymers and discusses their environmental benefits compared with traditional materials. It also addresses the issues of polymer durability, recycling processes to aid waste minimization and biodegradable polymers. This text is intended to introduce the non-specialist reader to the benefits and limitations of polymeric materials from an environmental viewpoint, and will prove a useful book for both students and professionals.

This book is about development of biodegradable polymers alternatives, which are required to save our reserves of fossil fuels and to save our mother earth from further environmental degradation. This book deals with the family of biodegradable polymers which have to be prepared with a novel idea of studying polymers with a “Cradle to Grave” approach. It touches upon basic materials, which can be potential materials to prepare biodegradable polymers with their basic structures, properties, behaviour and limitations known till date. This book will help students in understanding various characterization techniques which can be used for the study of identification of functional group, structural properties, thermal behaviour, crystallographic nature, mechanical properties and morphological properties through FTIR–ATR for physico chemical properties, DSC & TGA for thermal studies, XRD for crystallographic studies & SEM for morphological studies. It also provides an overview of various testing methods to analyse biodegradability including standard guideline for evaluation of biodegradation and compostability of polymer material through ASTM/ISO/EN standard methods. Note: T&F does not sell or distribute the Hardback in India, Pakistan, Nepal, Bhutan, Bangladesh and Sri Lanka.

Biodegradable plastics made with plant based materials have been available for many years. The term biodegradable means that a substance is able to be broken down into simpler substances by the activities of living organisms, and therefore is unlikely to persist in the environment. There are many different standards used to measure biodegradability, with each country having its own. The requirements range from 90 per cent to 60 per cent decomposition of the product within 60 to 180 days of being placed in a standard composting environment. They may be composed of either bio plastics, which are plastics whose components are derived from renewable raw materials, or petroleum based plastics which contain additives. Biodegradability of plastics is dependent on the chemical structure of the material and on constitution of the final product, not just on the raw materials used for its production. Polyesters play a predominant role as biodegradable plastics due to their potentially hydrolysable ester bonds. Bio based polymers are divided into three categories based on their origin and production; polymer directly extracted from biomass, polymers produced by classical chemical synthesis using renewable biomass monomer and polymers produces by microorganisms or genetically modified bacteria. In response to public concern about the effects of plastics on the environment and in particular the damaging effects of sea litter on animals and birds, legislation is being enacted or is pending in many countries to ban non degradable packing, finishing nets etc. This book basically deals with biodegradable plastics developments and environmental impacts, hydro biodegradable and photo biodegradable, starch synthetic aliphatic polyester blends, difference between standards for biodegradation, polybutylene succinate (pbs) and polybutylene, recent developments in the biopolymer industry, recent advances in synthesis of biopolymers by traditional methodologies, polymers, environmentally degradable synthetic biodegradable polymers as medical devices, polymers produced from classical chemical synthesis from bio based monomers, potential bio based packaging materials, conventional packaging materials, environmental impact of bio based materials: biodegradability and compostability, etc. Environmentally acceptable degradable polymers have been defined as polymers that degrade in the environment by several mechanisms and culminate in complete biodegradation so that no residue remains in the environment. The present book gives thorough information to biodegradable plastic and polymers. This is an excellent book for scientists engineers, students and industrial researchers in the field of bio based materials.
