This book highlights the positive and negative impacts that hemp fibre and textiles have on environment, while studying the effects of climate change on the growth of fibre hemp. Human-induced climate change challenge the availability of textile fibres, whereas today’s apparel industry leaves behind a substantial environmental footprint. Sustainable hemp textiles can lighten it. The book describes the environmental impact of hemp and how climate change influences future hemp growth. Hemp is considered in most literature as a sustainable alternative for the commonly used fibres polyester and cotton. However, most research does not go farther than the environmental impacts of hemp, and there is currently a lack of knowledge/literature that examines the possibilities of hemp growth under changing climate conditions.
The cannabis plant, as a hemp, could contribute better than previously thought to achieving the goals of the UN Sustainable Development Report, the so-called Agenda 2030 and its 17 SDGs (Sustainable Development Goals). From a health perspective, its medicinal use is the main focus, but it is also used in cosmetic products and in food offerings for humans and animals. In the context of the increasing climate crisis, hemp helps especially to cope with the CO2 problem: in agriculture by binding the CO2 similar to reforestation, in industry as a recyclable raw material substitute for example as a plastic substitute, in clothing, in technology or in construction. At the moment, unfortunately, the immense prices and high demand show a different picture, from citizens who want to but can't or aren't allowed to, from farmers who have to overcome immense bureaucratic hurdles to an industry that is deterred by complex rules and laws to invest. The essential shows how this potential could also be realized in Germany.
A comprehensive practical manual for professionals and self-builders, this innovative book explains the many benefits of building with hempcrete. Hempcrete is a building material with excellent, environmentally friendly properties. It's made from lime and hemp shivs (a waste product from hemp fibre growing) and can be used for walks, floor and roof insulation. Hempcrete is breathable, absorbing and emitting moisture; this helps regulate internal humidity, avoiding trapped moisture and mould growth, and creating healthier buildings. It provides excellent acoustic and thermal insulation, and it is lightweight, which reduces construction costs. Whether you're working on a new build or are planning a renovation, The Hempcrete Book tells you everything you need to know to get started with hempcrete. It describes how to source and mix it, and provides a detailed account of construction techniques, highlighting potential pitfalls and how to avoid them. With fully illustrated design notes and examples of completed builds, this book is a powerful tool for any eco-builder.
If there ever was a time to build an American hemp industry, the time is now. In Jesse Ventura’s Marijuana Manifesto, former Minnesota Governor teamed up with Jen Hobbs to explain why it’s time to fully legalize cannabis and end the War on Drugs. Through their research, it became clear that hemp needed its own manifesto. Jen Hobbs takes up this torch in American Hemp. December of 2018 marked a largely unprecedented victory for cannabis. The 2018 Farm Bill passed and with it hemp became legal. What the federal government listed for decades as a schedule 1 narcotic was finally classified as an agricultural crop, giving great promise to the rise of a new American hemp industry. Filled with catchall research, American Hemp examines what this new domestic crop can be used for, what makes it a superior product, and what made it illegal in the first place; the book also delves into the many health and medical benefits of the plant. Hobbs weighs in on how hemp can improve existing industries, from farming to energy to 3D printing, plus how it can make a serious impact on climate change by removing toxins from the soil and by decreasing our dependence on plastics and fossil fuels. American Hemp lays out where we are as a nation on expanding this entirely new (yet ancient) domestic industry while optimistically reasoning that by sowing hemp, we can grow a better future and save the planet in the process.
Most composites, particularly those made using thermoset resins, cannot be recycled or reused. As a result, most of them end up in landfills at the end of their useful life which is neither sustainable nor environment-friendly. Various laws enacted by Governments around the world and heightened global awareness about sustainability and global warming is changing this situation. Significant research is being conducted in developing and utilizing sustainable fibers and resins, mostly derived from plant, to fabricate 'Green' composites. The significant progress in the past 20 or so years in this field has led to the development of green composites with high strength or so called Advanced Green Composites. More interestingly, green composites have also acquired various different properties such as fire resistance, transparency, barrier to gases and others. The term 'advanced' which only included high strength and stiffness now includes all these special properties. The world is on the cusp of a major change, and once fully developed, such composites could be used in applications ranging from automobiles to sporting goods, from circuit boards to housing and from furniture to packaging. This book, by presenting the state-of-the-art developments in many aspects of advanced green composites adds significantly to the knowledge base that is critical for their success of expanding their use in applications never seen before. The chapters are written by world’s leading researchers and present in-depth information in a simple way. This provides readers and researchers the latest developments in the field of 'Green' resins (with ways of strengthening them), High Strength Green Fibers (including micro and nano-cellulose fibrils/fibers) and Green Composites in the first few chapters. The introductory chapter summarizes the consequences of using conventional, petroleum-based materials and the need for green composites as well as the progress being made in this field. After that the book delves in to Advanced Green Composites in a broader sense and includes chapters on High Strength Green Composites, Self-healing Green Composites, Transparent Green Composites, All-cellulose composites, Toughened Green Composites, Green Biofoams, Bioinspired Shape Memory Composites, etc. The chapters are written by the experts who are highly respected in their fields.

Using plant material as raw materials for construction is a relatively recent and original topic of research. This book presents an overview of the current knowledge on the material properties and environmental impact of construction materials made from plant particles, which are renewable, recyclable and easily available. It focuses on particles and as well on fibers issued from hemp plant, as well as discussing hemp concretes. The book begins by setting the environmental, economic and social context of agro-concretes, before discussing the nature of plant-based aggregates and binders. The formulation, implementation and mechanical behavior of such building materials are the subject of the following chapters. The focus is then put upon the hygrothermal behavior and acoustical properties of hempcrete, followed by the use of plant-based concretes in structures. The book concludes with the study of life-cycle analysis (LCA) of the environmental characteristics of a banked hempcrete wall on a wooden skeleton. Contents 1.
