The Complete Book on Biodegradable Plastics and Polymers (Recent Developments, Properties, Analysis, Materials & Processes) by NIIR Board of Consultants & Engineers Pdf
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.
Green Capitalism? by Hartmut Berghoff,Adam Rome Pdf
At a time when the human impact on the environment is more devastating than ever, business initiatives frame the quest to "green" capitalism as the key to humanity's long-term survival. Indeed, even before the rise of the environmental movement in the 1970s, businesses sometimes had reasons to protect parts of nature, limit their production of wastes, and support broader environmental reforms. In the last thirty years, especially, many businesses have worked hard to reduce their direct and indirect environmental footprint. But are these efforts exceptional, or can capitalism truly be environmentally conscious? Green Capitalism? offers a critical, historically informed perspective on building a more sustainable economy. Written by scholars of business history and environmental history, the essays in this volume consider the nature of capitalism through historical overviews of twentieth-century businesses and a wide range of focused case studies. Beginning early in the century, contributors explore the response of business leaders to environmental challenges in an era long before the formation of the modern regulatory state. Moving on to midcentury environmental initiatives, scholars analyze failed business efforts to green products and packaging—such as the infamous six-pack ring—in the 1960s and 1970s. The last section contains case studies of businesses that successfully managed greening initiatives, from the first effort by an electric utility to promote conservation, to the environmental overhaul of a Swedish mining company, to the problem of household waste in pre-1990 West Germany. Ranging in geographic scope from Europe to the United States, Green Capitalism? raises questions about capitalism in different historical, sociocultural, and political contexts.

Bioplastic is simply plastic that is created from a plant or other biological source rather than petroleum. It can be created by extracting sugar from plants like corn and sugarcane and converting it into polylactic acids (PLAs), or it can be made from microorganism-engineered polyhydroxyalkanoates (PHAs). Bioplastics are plastics made from renewable biomass sources such vegetable fats and oils, corn starch, straw, woodchips, sawdust, and recovered food waste, among others. Common plastics, such as fossil-fuel plastics (also known as petro-based polymers), on the other hand, are made from petroleum or natural gas. Biodegradable Products Manufacturing (Bio-Products) are all types of natural and artificial products that can be easily decomposed without causing any damage to the environment. The significant examples of Biodegradable Products are Biodegradable Plastic, Biodegradable Airline Meals, Bio-degradable Toilet Paper, Biodegradable Cups etc. It has become the need of the hour to use these products as most of the goods like Plastics take many years to decompose in nature and this affects the environment adversely with time. The worldwide bioplastics market is predicted to increase at a CAGR of 17.1 percent over the next five years. The packaging industry's rising product demand will propel the market even higher. The book covers a wide range of topics connected to bioplastics and biodegradable products, as well as their manufacturing processes. It also includes contact information for machinery suppliers, as well as images of equipment and plant layout. A comprehensive reference to manufacturing and entrepreneurship in the bioplastics and biodegradable products business.

Few scientific developments in recent years have captured the popular imagination like the subject of'biodegradable' plastics. The reasons for this are complex and lie deep in the human subconscious. Discarded plastics are an intrusion on the sea shore and in the countryside. The fact that nature's litter abounds in the sea and on land is acceptable because it is biodegradable - even though it may take many years to be bioassimilated into the ecosystem. Plastics litter is not seen to be biodegradable and is aesthetically unacceptable because it does not blend into the natural environment. To the environmentally aware but often scientifically naive, biodegradation is seen to be the ecologically acceptable solution to the problem of plastic packaging waste and litter and some packaging manufacturers have exploited the 'green' consumer with exaggerated claims to 'environmentally friendly' biodegradable packaging materials. The principles underlying environmental degradation are not understood even by some manufacturers of 'biodegradable' materials and the claims made for them have been categorized as 'deceptive' by USA legislative authorities. This has set back the acceptance of plastics with controlled biodegradability as part of the overall waste and litter control strategy. At the opposite end of the commercial spectrum, the polymer manufactur ing industries, through their trade associations, have been at pains to discount the role of degradable materials in waste and litter management. This negative campaign has concentrated on the supposed incompatibility of degradable plastics with aspects of waste management strategy, notably materials recycling.

Municipal Waste Disposal in the 1990s by Bela G. Liptak Pdf
This practical guide provides answers to questions about all facets of municipal waste treatment and disposal. Discover the latest standards, practices, and technology for handling landfills, hazardous waste disposal, sewage sludge, incineration, pollution-control equipment, HRIs, recycling, and more. Municipal solid waste (MSW) disposal has been a growing concern for decades. In the 1990s, the problems have multiplied and reached critical mass for many communities. This book examines various methods of treatment and disposal as "process control" examples on a societal scale. Technical enough for the municipal engineer who must make the solutions work, this book also provides the information needed by municipal leaders to evaluate MSW disposal options, and to select solutions that work today and won't harm future generations.
