SOLID WASTE ENGINEERING is one of a handful of engineering textbooks to address the growing and increasingly intricate problem of controlling and processing the refuse created by our urban society. While the authors discuss issues such as regulations and legislation, their main emphasis is on solid waste engineering principles. They maintain their focus on principles by first explaining the basic principles of the field, then demonstrating how these principles are applied in real world settings through worked examples.

This Tutorial Text provides a comprehensive introduction to the subject of contamination control, with specific applications to the aerospace industry. The author draws upon his many years as a practicing contamination control engineer, researcher, and teacher. The book examines methods to quantify the cleanliness level required by various contamination-sensitive surfaces and to predict the end-of-life contamination level for those surfaces, and it identifies contamination control techniques required to ensure mission success.

Solid waste has become a major consequence of development and modernization, yet some of the greatest challenges to its management are felt most keenly in the developing countries. This is part of the larger paradox of development; namely, that factors that create the most intransigent problems currently facing the developing countries are invariably those which derive from development itself.Introduction This volume presents a collection of papers which, with perspectives from Africa and the Caribbean, raise critical issues in the management of solid waste. It is intended to offer a basis for discussion among the wide range of disciplines and sectors involved in solid waste management and suggest directions for future work both in the theoretical and practical dimensions of the challenge with which developing countries are confronted.

Incidents in the past have made scientists aware of the need for accurate methods of radionuclide analyses in order to estimate the risk to the public from released radioactivity.

Representing the work of leading scientists from across the globe it presents information on radiochemical analysis, measurement of radioactivity, naturally occurring radioactive materials, radioactively contaminated land, fate of radionuclides in natural and engineered environments and behaviour and analysis of radionuclides in radioactive wastes. This essential work will be a key reference for graduates and professionals who work across fields involving analytical chemistry, environmental science and technology, and waste disposal.

This book provides an overview of biodegradation. The first chapter provides a detailed description on the ability of Rhodococcus UKMP-5M to act as a biological tool to remediate phenol, chlorinated compounds, nitrile, oil spillage and cyanide which selection was primarily based on their large-scale presence in industrial wastewater. Chapter Two presents advances made in recent decades on the understanding of the metabolic capabilities of sulfate reducing bacteria (SRB) from marine and other types of sediment (i.e., freshwater, estuarine) for the biotransformation of carbon compounds and sulfate that are present as pollutants in several types of waters and soils. Chapter Three concentrates on the different parameters that influence biodegradation speed and energy release potential. Chapter Four reports and discusses several examples on biodegradation with bacteria and fungi of organochlorides, organophosphates, and more recently of pyrethroid pesticides. Chapter Five discusses heavy metals as biodegradation inhibitors of the forest litter in contaminated areas. Chapter Six introduces ecologically feasible ways of treating environments contaminated by BTEX (a mixture of benzene, toluene, ethylbenzene and xylene) based on efficient microbial metabolism.

Water pollution occurs when toxic pollutants of varying kinds (organic, inorganic, radioactive and so on) are directly or indirectly discharged into water bodies without adequate treatment to remove such potential pollutants. Today's sources of these potential pollutants, which cause high deterioration of freshwater quality, are city sewage and industrial waste discharge, human agricultural practices, industrial waste disposal practices, mining activities, civil and structural work activities and obviously natural contamination with climate change. When our water is polluted, it is not only devastating to the environment but also to human health. Therefore, development of water and wastewater treatment processes to alleviate water pollution has been a challenging and demanding task for engineers, scientists and researchers. Perhaps this is even more challenging for underdeveloped and developing countries, where water and wastewater treatment facilities, knowledge and infrastructure are limited. Water and wastewater treatment processes are broad and often multidisciplinary in nature, comprising a mixture of research areas including physical, chemical and biological methods to remove or transform various potential pollutants. This is in hopes to achieve acceptable water quality and satisfy governmental and environmental protection agencies' laws and regulations. With these objectives, this book has been written in order to provide various research results and compilation and up-to-date development on the current states of knowledge and techniques in the broad field of water and wastewater treatment processes. Basically, this book will give a comprehensive understanding and advancement and application of various physical, chemical and biological treatment methods in the reduction of potential pollutants (inorganics/organics) from water and wastewater. There are a total 18 book chapters contributed by large number of expert authors around the world, covering the following main research areas: Physical, chemical and biological water treatment processes such as adsorption, biosorption, coagulation/flocculation, electrocoagulation, denitration, membrane filtration/separation, photo-catalytic reduction, advanced oxidation, nutrients removal by struvite crystallisation and nanotechnology; Physical, chemical and biological methods for municipal wastewater and industrial wastewater treatment plants such as primary-secondary sludge treatments, anaerobic digestions, aerobic treatment, activated sludge processes, dewaterability by flocculants, pre-treatments of sludge and rheology of sludge in wastewater treatment; Various operational units/equipment and process control of wastewater treatment plant.

A sustainable feedstock supply is one of the primordial issues for the transition towards the bio-based economy. Therefore, the resource base needs to be identified from the perspective of supply and demand. The exploitable biomass is of a highly heterogeneous origin, either derived from specially grown crops or from crop residues of food and feed production, forestry residues and marine flora. Municipal waste, manure and animal products and industrial wastes also need to be considered as potential resources for bio-based products and services. In this regard, enzymes are known to play a pivotal role not only at the stage of production of these value-added products, but also as an important component of value-added products from different alternative biomasses. Therefore, enzymes become an important factor as value-added products and for value-added products. The use of enzymes holds great potential value for industries in many sectors, including energy, organic chemicals, polymers, fabrics and healthcare products. In general, an enzyme based bio-economy offers many benefits and opportunities. For completed book description, please visit our link below.

Currently, the management of solid waste represents a major economic and environmental issue throughout the world. Trends in waste generation show an increase in the volumes of waste produced in most countries and it is clear that the trend will continue. The treatment and disposal of solid waste involves a range of processes including landfill, incineration and composting, all of which may result in emissions to the environment. Municipal investments are said to be highly capital-intensive. As a result, every investment needs to be preceded by the economic analysis which allows for the estimation of the effectiveness of the investment. Investments are made to make profits and to increase savings. This book presents current research in the study of municipal solid waste, with a particular focus on recycling and cost effectiveness.

The volume of waste produced by human activity continues to grow, but steps are being taken to mitigate this problem by viewing waste as a resource. Recovering a proportion of waste for re-use immediately reduces the volume of landfill. Furthermore, the scarcity of some elements (such as phosphorous and the rare-earth metals) increases the need for their recovery from waste streams. This volume of Issues in Environmental Science and Technology examines the potential resource available from several waste streams, both domestic and industrial. Opportunities for exploiting waste are discussed, along with their environmental and economic considerations. Landfill remains an unavoidable solution in some circumstances, and the current situation regarding this is also presented. Other chapters focus on mine waste, the recovery of fertilisers, and the growing potential for compost. In keeping with the Issues series, this volume is written with a broad audience in mind. University students and active researches in the field will appreciate the latest research and discussion, while policy makers and members of NGOs will benefit from the wealth of information presented.

Waste management is the collection, transport, processing, recycling or disposal of waste materials. The term usually relates to materials produced by human activity, and is generally undertaken to reduce their effect on health, aesthetics or amenity. Waste management is also carried out to reduce the materials' effect on the environment and to recover resources from them. Waste management can involve solid, liquid or gaseous substances, with different methods and fields of expertise for each. Waste management practices differ for developed and developing nations, for urban and rural areas, and for residential and industrial, producers. Management for non-hazardous residential and institutional waste in metropolitan areas is usually the responsibility of local government authorities, while management for non-hazardous commercial and industrial waste is usually the responsibility of the generator. This book concentrates on the newest research in the field.

Uganda's capital, Kampala, is undergoing dramatic urban transformations as its new technocratic government seeks to clean and green the city. Waste Worlds tracks the dynamics of development and disposability unfolding amid struggles over who and what belong in the new Kampala. Garbage materializes these struggles. In the densely inhabited social infrastructures in and around the city's waste streams, people, places, and things become disposable but conditions of disposability are also challenged and undone. Drawing on years of ethnographic research, Jacob Doherty illustrates how waste makes worlds, offering the key intervention that disposability is best understood not existentially, as a condition of social exclusion, but infrastructurally, as a form of injurious social inclusion.

This book deals with natural treatment systems and the challenges the water industry faces in dealing with sustainability and the realisation of reaching Net Zero by 2030.Surface waters are all under threat, with freshwater ecosystems now facing unprecedented levels of contamination, even after a century of ever stricter legislation and regulation. The increase in population and especially in urbanization without sufficient planning and investment to ensure adequate wastewater collection and treatment coupled with the need to reduce greenhouse gas emissions associated with wastewater treatment is leading to a crisis in wastewater treatment in many countries.Natural treatment systems which use plants and soil micro-organisms are very much nature-based solutions and wherever applicable might offer sustainable and low emissions options for a range of wastewater problems protecting surface waters as well as creating new habitats to support and enhance wildlife diversity. In terms of circularity, natural treatment systems have the potential to produce a staggering array of useful and valuable by-products, including high-value compounds for the pharmaceutical industry.Related Link(s)
