Book Description
After price and delivery time, the most frequently asked question about a product is 'How long will it last?' Lifetime expectancy is often many years, the service conditions may be complex, and there is a scarcity of definitive data on durability. The situation is complicated by the fact that there are a vast number of degradation agents, service conditions, properties of importance and different plastics. There are many inherent difficulties in designing durability tests. In many cases, the time scale involved is such that accelerated test conditions are essential. Whilst large amounts of durability data are generated by accelerated methods, much of it is only useful for quality control purposes and relatively little has been validated as being realistically capable of representing service. Most assessments of the lifetime of plastics are made by considering some measure of performance, such as impact strength, and specifying some lower limit for the property, which is taken as the end point. Lifetime is not necessarily measured in time. For example, for some products it will be thought of as the number of cycles of use. The object of this publication is to provide practical guidance on assessing the useful service life of plastics. It describes test procedures and extrapolation techniques together with the inherent limitations and problems. The Guide aims to make available the wealth of information that can be applied to help maximise the effectiveness of a durability-testing programme. This guide seeks to be comprehensive but concentrates on the most common environmental effects causing degradation. The test procedures used are outlined and the relevant textbooks and international standards are well referenced. Examples of lifetime testing studies are cited. The Practical Guide will be useful for anyone responsible for designing, manufacturing or testing plastic components. It will also be of benefit to suppliers and users of end products, as assessment of useful lifetime is critical to the economics and safety aspects of any component.

Book Description
A Practical Guide to Plastics Sustainability: Concept, Solutions, and Implementation is a groundbreaking reference work offering a broad, detailed and highly practical vision of the complex concept of sustainability in plastics. The book's aim is to present a range of potential pathways towards more sustainable plastics parts and products, enabling the reader to further integrate the idea of sustainability into their design process. It begins by introducing the context and concept of sustainability, discussing perceptions, drivers of change, key factors, and environmental issues, before presenting a detailed outline of the current situation with types of plastics, processing, and opportunities for improved sustainability. Subsequent chapters focus on the different possibilities for improved sustainability, offering a step-by-step technical approach to areas including design, properties, renewable plastics, and recycling and re-use. Each of these pillars are supported by data, examples, analysis and best practice guidance. Finally, the latest developments and future possibilities are considered. - Approaches the idea of sustainability from numerous angles, offering practical solutions to improve sustainability in the development of plastic components and products - Explains how sustainability can be applied across plastics design, materials selection, processing, and end of life, all set alongside socioeconomic factors - Considers key areas of innovation, such as eco-design, novel opportunities for recycling or re-use, bio-based polymers and new technologies

Book Description
This book presents the state of the art on the weathering of polymers and plastic materials in outdoor applications, comprising natural weathering, accelerated climatic weathering, laboratory artificial accelerated weathering, and lifetime prediction methodology. It summarizes the most suitable methods of instrumental analysis to access and quantify (when possible) degradation caused by weathering, while also covering the degradation and stabilization of polymers based on environmental and artificially induced factors. Innovative polymer additives and some developments in polymeric materials designed for outdoor applications are also included, emphasizing a few selected cases. the book intends to be an important reference source for those involved in the study of the durability of polymers and plastics, production of plastics for exterior applications, chemists responsible for quality control of plastic products, and researchers and students across plastics engineering, polymer science, polymer chemistry and environmental science.

Book Description
Plastics to Energy: Fuel, Chemicals, and Sustainability Implications covers important trends in the science and technology of polymer recovery, such as the thermo-chemical treatment of plastics, the impact of environmental degradation on mechanical recycling, incineration and thermal unit design, and new options in biodegradable plastics. The book also introduces product development opportunities from waste materials and discusses the main processes and pathways of the conversion of polymeric materials to energy, fuel and chemicals. A particular focus is placed on industrial case studies and academic reviews, providing a practical emphasis that enables plastics practitioners involved in end-of-life aspects to employ these processes. Final sections examine lifecycle and cost analysis of different plastic waste management processes, exploring the potential of various techniques in modelling, optimization and simulation of waste management options. - Introduces new pathways for the end-of-life treatment of plastics and polymers, including conversion to energy, fuel and other chemicals - Compares different options to assist materials scientists, engineers and waste management practitioners to choose the most effective and sustainable option - Covers the latest trends in the science and technology of polymer energy recovery

Book Description
Geosynthetics often play critical roles in civil engineering and it is important that the materials in use can withstand the physical and chemical pressures of the environment. These range from resistance to leachates from landfill to resistance to root damage in soil liners, as well as standard properties such as resistance to creep, oxidation and UV light, and tensile strength. This Rapra Review Report discusses the polymers used in each category of geosynthetics, production methods, test methods and applications. The review is accompanied by around 400 abstracts from papers and books in the Rapra Polymer Library database, to facilitate further reading on this subject.

Book Description
Plastic plays a vital role in today's world but has become increasingly problematic. Plastics and Microplastics: A Reference Handbook discusses the history and evolution of plastic and its many uses, both in the United States and around the world. Beginning with a history of plastic—from the first scientific discovery of the material to its diversity of forms and uses in the present day—Plastics and Microplastics: A Reference Handbook discusses the history and evolution of plastic and its many uses, both in the United States and around the world. Importantly, it delves into the problems and controversies concerning plastic and microplastics, such as the pollution of oceans, rivers, and streams; its exceptionally long shelf life; its contribution to air pollution; and ingestion of microplastics by marine life. One of the most valuable aspects of the book is its survey of the history of plastics and microplastics conducted in a manner that helps readers to identify key issues to address. Moreover, it discusses both implemented and proposed solutions. A perspectives chapter includes a broad range of voices, allowing crucial, diverse perspectives to round out the author's expertise.
