Download or read book Polymers for Agri Food Applications written by Tomy J. Gutiérrez and published by Springer. This book was released on 2019-08-02 with total page 620 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Biodegradation of Plastics written by Zhanyong Wang and published by Frontiers Media SA. This book was released on 2023-11-21 with total page 109 pages. Available in PDF, EPUB and Kindle. Book excerpt: The consumption of plastic products has increased significantly with the rapid development of the global economy. The total output of virgin plastics has already reached eight billion tons, and the annual global plastic consumption has reached 2.8 billion tons. In parallel with this high consumption rate, a staggering amount of plastic waste is generated annually. As a consequence of incorrect disposal of waste plastics and plastic longevity, this plastic waste is accumulating in the environment at an increasing rate. Moreover, since most plastic waste is corrosion resistant, these plastics do not decompose in the natural environment and can cause serious environmental pollution. In particular, petroleum-based synthetic polymers, including polyethylene, polyvinyl chloride, polystyrene, polypropylene, polyethylene terephthalate, and polyurethanes need hundreds of years to completely degrade in the natural environment. Moreover, although some aliphatic polyesters, such as polybutylene succinate, polycaprolactone, and polylactic acid are considered biodegradable, degradation of these plastics occurs only under specific microorganism activity and under specific conditions. Sometimes the apparent degradation is initiated by hydrolytic activity and not microorganism or enzymatic activity. Large-scale synthesis and application of plastics only began after 1950. Hence, the time span of plastic exposure in the environment has been too short for the adaptive evolution of natural microorganisms. Indeed, natural microorganisms showing high specificity for plastics and a high degradation efficiency are extremely scarce. Because of the inability of most natural microorganisms to recognize and degrade plastics, enzymes that can specifically degrade plastics are also scarce. Many of the enzymes which are known have either an unclear mechanism of the action on the polymer, a poor affinity for their substrates, a low efficiency, or enzyme production yield is currently low. To address these problems, new biotechnology strategies need to be implemented. In particular, new microorganisms and their enzymes need to be identified, and pathways for plastic degradation and molecular modification need to be clarified to enhance the activity and stability of the degrading enzymes. The current Research Topic aims to cover the recent and novel research trends in the development of plastics biodegradation (including petroleum-based plastics and bio-based plastics) under soil, composted, microbial and enzymatic conditions. The recycling technology of degraded products is also of interest.

Available in PDF, EPUB and Kindle. Book excerpt: The recent explosion of interdisciplinary research has fragmented the knowledge base surrounding renewable polymers. The Chemistry of Bio-based Polymers 2nd edition brings together, in one volume, the research and work of Professor Johannes Fink, focusing on biopolymers that can be synthesized from renewable polymers. After introducing general aspects of the field, the book’s subsequent chapters examine the chemistry of biodegradable polymeric types sorted by their chemical compounds, including the synthesis of low molecular compounds. Various categories of biopolymers are detailed including vinyl-based polymers, acid and lactone polymers, ester and amide polymers, carbohydrate-related polymers and others. Procedures for the preparation of biopolymers and biodegradable nanocomposites are arranged by chemical methods and in vitro biological methods, with discussion of the issue of “plastics from bacteria.” The factors influencing the degradation and biodegradation of polymers used in food packaging, exposed to various environments, are detailed at length. The book covers the medical applications of bio-based polymers, concentrating on controlled drug delivery, temporary prostheses, and scaffolds for tissue engineering. Professor Fink also addresses renewable resources for fabricating biofuels and argues for localized biorefineries, as biomass feedstocks are more efficiently handled locally.

Download or read book Biodegradability of Biodegradable Mulch Film written by Maarten van der Zee and published by . This book was released on 2021 with total page 25 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report presents the findings of a desk study, commissioned by NRK-V and executed independently by WFBR. The objective of the desk study is to provide insight in the information available in the public and scientific literature regarding the biodegradability of biodegradable mulch film for use in agriculture and horticulture. Biodegradability of plastic describes the potential to undergo biodegradation in a suitable environment. Biodegradation does not only depend on the chemistry of the polymer, but also on the presence and activity of the biological systems involved in the process. This means that biodegradability in soil can be different from biodegradability in industrial composting conditions. The biodegradation of plastic is defined as its complete microbial utilization, resulting in its conversion to CO2, (and/or CH4), water and biomass by the metabolic activity of microorganisms. Not all materials labelled ‘biodegradable’, ‘oxo-(bio)degradable’ or ‘compostable’ will actually biodegrade at sufficient rate at ambient temperatures in soil to prevent accumulation of plastic (residues) in the field. Typically, mulch films are produced by combining polymeric feedstocks with other components (via master batches), such as processing aids, plasticizers and colorants, which are then further processed through extrusion into film. Regarding biodegradability and environmental fate it is important to consider not only the polymeric constituents, but all components that are used to produce the mulch film. In this report the biodegradability is discussed of the main polymeric constituents commonly employed for biodegradable mulch film. These include (thermoplastic) starch and several polyesters, including poly(butylene adipate-co-terephthalate) (PBAT), poly(butylene succinate) (PBS), poly(lactic acid) (PLA) and poly(hydroxy alkanoate) (PHA). It is important to realize that general statements regarding the biodegradability of these polymers are not possible, because variations of comonomer composition, molar mass, etc. within a polymer family, can have substantial effects on physical properties and biodegradation behaviour. Polymer grades that have passed the biodegradability requirements as stipulated in EN 17033 are likely to actually biodegrade to CO2 and water (and biomass) at sufficient rate when applied in agri- or horticulture in the Netherlands. Certification according to ‘DIN geprüft Biodegradable in soil’, ‘OK Biodegradable SOIL’, ‘OK compost HOME’ and ‘DIN Geprüft Home compostable’ is considered a reliable confirmation that fulfilment of the biodegradability requirements of EN 17033 has been demonstrated.
