This book analyses 'zero-waste' (ZW) as an emerging waste management strategy for the future, which considers waste prevention through innovative design and sustainable consumption practices. Drawing on a diverse range of case studies from Australia, Bangladesh, Japan, New Zealand, Sweden, and the USA, this book explores why urban waste management systems still remain a major challenge for almost all cities around the world. Rejecting waste as an 'end-of-life' problem, Atiq Zaman and Tahmina Ahsan instead consider waste prevention through the ZW model, in which resources are utilized and consumed with minimum environmental degradation. In addition, the authors give extended discussion on why embracing the ZW concept will be beneficial for the circular economy (CE). Providing a strategic zero-waste framework and an evaluation tool to measure waste management performance aimed towards ZW goals, this book will be of great relevance to students, scholars, and policymakers with an interest in waste management, sustainable consumption, urban planning, and sustainable development.

Industrial wastewater contains many pollutants. This book focuses on heavy metals found in textile effluents because of their known toxicity effect in the environment. Wastewater from a textile industry (UTEXRWA) in Rwanda has been screened for the occurrence of Cd, Cr, Cu, Pb, and Zn. Batch and pilot experiments on adsorption equilibrium, kinetics, and sulfide precipitation using volcanic rock as adsorbent and packing material have been investigated. A low cost and integrated system for treatment has been developed, combining an anaerobic bioreactor as the main treatment step, followed by a polishing step composed by a polishing pond containing algae, duckweed, and water hyacinth. More than 90% of metal removal was achieved in the bioreactor, with metal sulfide precipitation as long-term removal mechanism. The use of algae and duckweed as alternatives for water hyacinth plants showed no differences between algae and duckweed ponds based on abiotic differences. Overall, both systems' performance was close and these systems are well suited as a polishing step for wastewater containing low metal concentrations. The integrated system for heavy metal removal showed how two complementary systems for heavy metal removal can work in combination and good removal performance can therefore be achieved.

Waste electrical and electronic equipment (WEEE) generation is a global problem. Despite the growing awareness and deterring legislation, most of the WEEE is disposed improperly, i.e. landfilled or otherwise shipped overseas, and treated in sub-standard conditions. Informal recycling of WEEE has catastrophic effects on humans and the environment. WEEE contains considerable quantities of valuable metals such as base metals, precious metals and rare earth elements (REE). Metal recovery from WEEE is conventionally carried out by pyrometallurgical and hydrometallurgical methods. In this PhD research, novel metal recovery technologies from WEEE are investigated. Using acidophilic and cyanide-generating bacteria, copper and gold were removed from crushed electronic waste with removal efficiencies of 98.4 and 44.0%, respectively. The leached metals in solution were recovered using sulfidic precipitation and electrowinning separation techniques. Finally, a techno-economic assessment of the technology was studied. This research addresses the knowledge gap on two metal extraction approaches, namely chemical and biological, from a secondary source of metals. The essential parameters of the selective metal recovery processes, scale-up potential, techno-economic and sustainability assessment have been studied.

Construction and Demolition Waste (CDW), from the construction, maintenance, renovation and demolition of buildings and structures, represents a large proportion of the waste in industrialized societies. Compared to other forms, such as household waste, more than 90% of CDW can be used as a resource and a substitute for construction materials, especially for primary, natural raw materials. Reuse, recovery and recycling depends on the quality and market for the materials, and the environmental impact of the processes for conversion of CDW from old structures to its use in new structures. However, the utilization today of CDW products as secondary resources is marginal. Most CDW is deposited or used as fill material, and the opportunities of high quality recycling are generally neglected. This book presents the opportunities for the sustainable and resource efficient utilisation of CDW, focusing on recycling of concrete and masonry as the major forms of CDW. The recycling of gypsum, timber, mineral wool, asphalt and other types are also described. Its aim is to present a chain of value and material streams in the transformation of obsolete buildings and structures into new buildings and structures. It takes a holistic view, focusing on the lifecycle economy (the circular economy) and integrated management aspects of various scenarios ranging from high industrial urban renewal to debris removal and management after disasters and conflicts. It is based on the authors 35 years of research and development combined with practical international experience within the demolition and recycling area. It addresses students, architects, civil engineers, building owners, public authorities and others working in urban planning, demolition and resource management in the building and construction sector and in the reconstruction of damaged buildings after disasters and wars.

Scientific practices of removing waste in mega-cities of the global South are embedded in socio-cultural belief systems which reproduce existing social hierarchies. Thus going beyond a techno-managerial approach in waste management, Sneha Sharma critically interrogates the politics around urban waste disposal in Mumbai, India. She undertakes an ethnographic journey to the city's most unwanted space, a dumping site, to reveal how spaces and people are made into waste through exclusionary formal and informal practices. Offering new insights on topics of urban marginality, informality, urban planning this book will attract scholars from sociology, urban studies, and human geography.

In the past 13 years since the publication of Longwall Mining, 2nd edition in 2006, although there have been no major changes in longwall mining technology and operations, many incremental developments in the whole system as well as various subsystems of the existing longwall mining operational technologies as detailed in the 2nd edition have been added to this edition. Major developments are automation, and health and safety technology, as well as equipment reliability, thereby greatly increasing productivity and cutting cost. In particular, the longwall system can now run automatically cut by cut forever without operators' intervention provided that the geology allows it. Other health and safety features such as LASC, personal proximity detection, color lighting, automatic shield water sprays and remote shearer control are fully operational. There are more than 7000 sensors installed in current longwall mining systems. The big data obtained and fast communication technology have been fully utilized to improve and solve operational problems in real time. Those features are fully documented in the new edition. In pursuit of high productivity and cutting cost, life cycle management that increases equipment reliability has been implemented by OEM. Automation improvement such as tail-end automatic chain tensioner greatly extends AFC chain's service life. Other incremental improvements including dust and methane controls, entry development, panel design and face move are addressed. Additional operational issues such as extension of panel width and compatibility test are also discussed. Since the last plow longwall mine was closed in 2018, the chapter on plow longwalling has been dropped and in its place Automation of Longwall Components and System is added. Also, a new chapter Longwall Top Coal Caving Mining (LTCC) is added due to its successful application in Australia since 2005. Longwall Mining, 3rd edition will be of interest to professionals and academics in the field of mining engineering specifically, serving both as a reference work and an (under)graduate textbook, but will also interest civil, geomechanical and geological engineers and rock mechanics professionals, as well as coal operators, mining consultants, researchers, equipment manufacturers, and government regulators.

With the increased interest in and demands for compost from commercial horticultural industries, composting is on the verge of becoming an economically feasible option for waste management. While horticultural producers can create some of the compost to meet their own needs, demand has grown beyond what they can supply for themselves and others. Compost Utilization in Horticultural Cropping Systems gives you the tools to meet the needs of this growing industry. Consider these statistics: Americans generate about 200 million megagrams of municipal solid waste per year The agricultural market for compost could reach over 680 million m3 per year Two horticultural areas together account for over 50% of compost use: landscaping (31%) and food crop production (25%) Now consider this: Proven benefits of compost use, including plant disease suppression, better moisture retention, supplying plant nutrients, and building soil organic matter Increased pressure on peat supplies and wider availability of compost products Creation of composting enterprises by the horticultural industry in response to its own needs, rising disposal fees for organic waste, and consumer demand for compost at retail centers The first book to establish a composite of the existing scientific knowledge on the use of compost in commercial horticultural enterprises, Compost Utilization in Horticultural Cropping Systems gives you a comprehensive review of the production, use, and economics of compost. It covers production methods, compost quality and the parameters associated with its measurement, and the biological, chemical, and physical processes that occur during composting. Rather than searching for information in various places, now you can find all the information you need in one convenient source.

Every day, every one of us contributes to the waste problem but, despite being a part of our lives, waste is poorly understood, even by those who should know better. We live in a throw-away society and yet what is discarded is a vital raw material and ingredient being traded as a valuable commodity around the world. Recycling our Future provides an insight into the challenges facing the industry and individuals as the world contemplates expanding waste mountains. Finite sources are being eroded as the world's growing and increasingly affluent population demands a better standard of living with bigger houses, new TVs, computers, etc. Waste is a valuable raw material when treated correctly but a hazard when neglected. The author warns of illegal shipments of waste continuing unabated, and highlights the pressures and challenges facing governments and the industry. He also explains how the system works from the moment a carton is dropped into a bin to being recycled, resold and restocked on supermarkets' shelves. He explodes the myths about waste recycling, looks at the technology that is used and explains why the subject matters to everyone.The book is supported by information from sources around the world and the author reveals how so-called rubbish has a value, how it is traded on the financial markets and suggests that waste should be treated as a prize worthy of investment, rather than a problem to be shunned.

In this collection, the authors report on the pretreatment methods for waste activated sludge based on pulsed electric field and corona discharge techniques. The effects of pulse magnitude, frequency, temperature and pretreatment time are demonstrated on the basis of cell membrane electroporation. The influence of voltage polarity, frequency, magnitude, treating time and temperature has also been demonstrated. A description of fundamental techniques in molecular biology for the analysis of the microbiota of activated sludge is provided. Activated sludge is a heterogeneous system of organisms, organic and inorganic material, and therefore giving a specific protocol for each molecular technique would be imprudent. The authors go on to discuss the Monod model, which provides a functional relationship between specific growth rate and substrate concentration in the bulk. Important research efforts dedicated to adequate use of the Monod model are presented, consolidating knowledge from activated sludge and biofilm modelling, identifying misdirections, and setting parameters for further research. In one study, different microwave power outputs and times were optimised for sludge solubilisation without evaporation loss in waste activated sludge from two different sources. The variable effects of pre-treatments on extracellular polymeric substances fraction, cellular oxidative stress and solubilisation of both sludges were evaluated to understand the impact of sludge complexity. The penultimate chapter examines how toxic carbon sources can cause higher residual effluent dissolved organic carbon than easily biodegraded carbon sources in the activated sludge process. Based on the variations of chemical components of activated sludge, mainly intracellular storage materials, extracellular polymeric substances and soluble microbial products, the performance and mechanism of toxic carbon on the activated sludge process can be clarified. The purpose of the final study is to research the supplementation of different concentrations of substrate on the degradation rate of xenobiotics, and to determine the optimal concentrations of auxiliary substrates that are most beneficial. The results show that sugar and peptone can affect 2,4-D degradation rate by several different degrees at different concentrations.

Modern societies produce large amounts of waste of many different types. This presents a problem in terms of management or disposal to prevent harm to human health and the environment. Additionally it represents a loss of potentially useful resources. In the circular economy concept nothing would ever become waste because everything would be re-usable or its components recoverable. Ionic liquids provide a potential route for valorisation of different waste types, paving the way for a circular economy and a more sustainable world. Covering various types of waste, including municipal, industrial, electronic, and medical, while addressing patented and commercial applications, this book aims to deliver a comprehensive, but also critical, perspective on the application of ionic liquids towards waste valorisation. Waste Valorisation Using Ionic Liquids is a useful resource for academic and industrial players, in the fields of chemistry, chemical and environmental engineering, and biotechnology, as well as anyone working on waste management and resource recovery.

"Everything looked perfect. Sand - unique Baltic sand, the best in the world - and the calm sea. But wait. Something was amiss. Something was wrong" It starts with a day at the beach. A single white sock that somehow spoils everything. It's enough to send writer and ornithologist Stanislaw Lubienski on a quest to understand what we throw away, where it goes and whether it will be our legacy. By analysing items he unearths on his trips into nature - a plastic bottle, a tube of Russian penis-enlargement cream, a cigarette butt, an empty aerosol can - tracing their origins and explaining the harm they can do, he shows how consumer society has developed out of control, to the point of environmental catastrophe. He also looks with a birdwatcher's eye at how various animals have come to adapt to and even rely on our rubbish, and interrogates the cultural significance of waste and the origins of our throw-away lifestyles. Finally, he adds a personal touch by examining his own "environmental neurosis" and by going out with refuse crews to watch them work. While Lubienski never hectors his readers, nor shames them, his clear-eyed, persuasive and humble polemic reminds us what we, as individuals, can and cannot do to address an apocalyptic issue while there's still something worth saving.

Recycling and Reuse of Materials begins by discussing the production of glass and ceramic products on the basis of recycling of decommitted products and residuals. Examples are given for production of foam glass, porous ceramic bodies and ceramic pigments from wastes and residuals originated from the same sector. The authors provide a comprehensive description of the recent trends and incoming approaches for creation of environmentally-friendly concepts for further development of the glass and ceramic industrial sectors. In the following study, options for conserving the functionality of geochemically scarce elements associated with aluminum life cycles are reviewed, including but not limited to changes in the diversity of Al alloys and in the composition of aluminum alloys and coatings. Lastly, the authors describe the manufacturing of an ecological ceramic tile, containing high percentage of industrial waste or sub-products coming from the ceramic and the recycled glass sector. The addition of these subproducts was performed in the three layers of the ceramic tile.

"Trash is a bit like birds. Both have their favourite habitats. I thought it might be worth taking a closer look at what we throw away and what it says about us. To follow the journey of the items we buy and discard. I wanted to find out more about what they're made of and what fate the future has in store for them." It starts with a day at the beach. A single white sock in the sand that somehow seems to spoil everything. It's enough to send Polish reporter and ornithologist Stanislaw Lubienski on a quest to understand what we throw away, where it goes and whether it will be our lasting legacy. By analysing items he unearths on his trips into nature - a plastic bottle, a tube of Russian penis-enlargement cream, a cigarette butt, an empty aerosol can - tracing their origins, their destination and the harm they can do, he shows how our consumer society has developed out of our control, to the point of environmental catastrophe. He also looks with a birdwatcher's eye at how various animals have come to adapt to and even rely on the rubbish we pollute their environment with, and at the cultural significance of trash and rubbish and the origins of our throw-away society. And in the finest Gonzo traditions, he inserts himself into his narrative by exmaning his own "environmental neurosis" and by going out with refuse crews to watch them work.
