This book presents an exhaustive analysis of the trends in the development and use of natural and synthetic polymer systems aimed at sustainable agricultural production. The polymers have allowed the development of controlled and released systems of agrochemicals such as pesticides, fertilizers and phytohormones through micro and nanoencapsulated systems, which protect and stimulate the growth of crops at low costs and without damage to the environment. Hydrogel systems from natural and synthetic polymers have also had their place in the agricultural industry, since they allow to maintain the humidity conditions of the crops for their correct development in drought times. Mulch films made of polymers have also become important in the control of weeds and pests in crops, as well as the use of edible coatings applied to fruits and vegetables during post-harvest, which reduce the losses of these perishable foods. Currently, the systems indicated, as well as others, are already used on a large scale. However, research studies in this area have been limited compared to other polymer applications. This book collects useful information for researchers, students and technologies related to the polymer technology and agri-food production. In this book, world-renowned researchers have participated, including associate editors of important journals, as well as researchers working in the area of research and development (R&D) of leading agri-food industries in the manufacture of agricultural inputs.

Biopolymers are polymers that are naturally sourced from renewable resources such as plants, animals, and microorganisms. These polymers are gaining increasing attention due to their biodegradability, biocompatibility, and non-toxicity, making them an attractive alternative to traditional synthetic polymers. "Biopolymeric Nanoparticles for Agricultural Applications" focuses on the use of biopolymeric nanoparticles for various agricultural purposes. It explores the potential of these nanoparticles in improving crop productivity, enhancing soil quality, and reducing the environmental impact of agricultural practices. Biopolymeric nanoparticles have gained significant attention in recent years as a promising technology for various agricultural applications such as crop protection, nutrient delivery, and soil remediation. These nanoparticles are typically made from biodegradable and biocompatible materials, such as chitosan, alginate, and starch, and offer several advantages over conventional agricultural formulations including improved stability, controlled release, and enhanced efficacy. This book provides a comprehensive overview of recent advances in the design, synthesis, characterization, and application of biopolymeric nanoparticles in agriculture. It discusses the various biopolymeric nanoparticles that can be utilized in agriculture such as chitosan, cellulose, starch, and protein-based nanoparticles. It delves into their properties, synthesis methods, and characterization techniques. The primary purpose of this book is to provide a comprehensive understanding of the applications of biopolymeric nanoparticles in agriculture. It bridges the gap between the fields of nanotechnology and agriculture, offering insights into the potential benefits and challenges associated with their use.

In this data book, both conventional Py-GC/MS where thermal energy alone is used to cause fragmentation of given polymeric materials and reactive Py-GC/MS in the presence of organic alkaline for condensation polymers are compiled. Before going into detailed presentation of the data, however, acquiring a firm grip on the proper understanding about the situation of Py-GC/MS would promote better utilization of the following pyrolysis data for various polymers samples. This book incorporates recent technological advances in analytical pyrolysis methods especially useful for the characterization of 163 typical synthetic polymers. The book briefly reviews the instrumentation available in advanced analytical pyrolysis, and offers guidance to perform effectually this technique combining with gas chromatography and mass spectrometry. Main contents are comprehensive sample pyrograms, thermograms, identification tables, and representative mass spectra (MS) of pyrolyzates for synthetic polymers. This edition also highlights thermally-assisted hydrolysis and methylation technique effectively applied to 33 basic condensation polymers. - Coverage of Py-GC/MS data of conventional pyrograms and thermograms of basic 163 kinds of synthetic polymers together with MS and retention index data for pyrolyzates, enabling a quick identification - Additional coverage of the pyrograms and their related data for 33 basic condensation polymers obtained by the thermally-assisted hydrolysis and methylation technique - All compiled data measured under the same experimental conditions for pyrolysis, gas chromatography and mass spectrometry to facilitate peak identification - Surveyable instant information on two facing pages dedicated to the whole data of a given polymer sample

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 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

The purpose of this book will be to demonstrate 1) the newly developed method of using reactive functionalized materials in agriculture to solve the economic and public health problems associated with using conventional agrochemicals; and 2) new technology aimed at achieving the greening of chemistry to meet appropriate environmental standards in both agriculture and industrial foodstuffs production. More specifically, the book will accomplish this goal by addressing 3 key issues in the field: 1) the production of reactive functionalized materials with enhanced properties that offer a major opportunity to overcome the disadvantages of using traditional materials; 2) the applications of functionalized materials in agriculture for the purpose of solving the economic and the environmental pollution problems associated with the uses of conventional agrochemicals; and 3) the contribution of polymers in solving problems associated with conventional procedures of food growth and processing, including those used in the dairy industry, sugar and fruit juices, beer and wine production, nutritive and nonnutritive food additives, and in food protection.
