Waste Management and Resource Recycling in the Developing World
provides a unique perspective on the state of waste management and
resource recycling in the developing world, offering practical
solutions based on innovative tools and technologies, along with
examples and case studies. The book is organized by waste type,
including electronic, industrial and biomedical/hazardous, with
each section covering advanced techniques, such as remote sensing
and GIS, as well as socioeconomic factors, transnational transport
and policy implications. Waste managers, environmental scientists,
sustainability practitioners, and engineers will find this a
valuable resource for addressing the challenges of waste management
in the developing world. There is high potential for waste
management to produce energy and value-added products. Sustainable
waste management based on a circular economy not only improves
sanitation, it also provides economic and environmental benefits.
In addition to waste minimization, waste-to-economy and
waste-to-energy have become integral parts of waste management
practices. A proper waste management strategy not only leads to
reduction in environmental pollution but also moves toward
generating sufficient energy for improving environmental
sustainability in coming decades.
"One smart book...delving deep into the history and implications
of a daily act that dare not speak its name."--"Newsweek
"
Bodily waste is common to all and as natural as breathing. We
prefer not to talk about it, but we should--even those of us who
take care of our business in pristine, sanitary conditions. Disease
spread by bodily waste kills more people worldwide every year than
any other single cause of death. Even in the United States, nearly
two million people have no access to an indoor toilet, while the
sewers of major cities worldwide are an infrastructure disaster
waiting to happen. With razor-sharp wit and crusading urgency,
mixing levity with gravity, "The Big Necessity" breaks the silence,
turning the taboo subject into a cause with the most serious of
consequences.
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 provides authoritative information, techniques and data
necessary for the appropriate understanding of biomass and biowaste
(understood as contaminated biomass) composition and behaviour
while processed in various conditions and technologies. Numerous
techniques for characterizing biomass, biowaste and by-product
streams exist in literature. However, there lacks a reference book
where these techniques are gathered in a single book, although such
information is in increasingly high demand. This handbook provides
a wealth of characterization methods, protocols, standards,
databases and references relevant to various biomass, biowaste
materials and by-products. It specifically addresses sampling and
preconditioning methods, extraction techniques of elements and
molecules, as well as biochemical, mechanical and thermal
characterization methods. Furthermore, advanced and innovative
methods under development are highlighted. The characterization
will allow the analysis, identification and quantification of
molecules and species including biomass feedstocks and related
conversion products. The characterization will also provide insight
into physical, mechanical and thermal properties of biomass and
biowaste as well as the resulting by-products.

This publication provides essential information on the planning,
implementation, and management of improved water, sanitation, and
hygiene (WASH) in schools, particularly for small and isolated
rural settlements in Mongolia. Many schools in Mongolia face
significant challenges in improving WASH due to physical and
demographic conditions. The country's harsh winters require
sustainable WASH facilities that can withstand extended periods of
below-freezing temperatures. Information about WASH standards and
norms, design and technology options, operation and maintenance,
hygiene education approaches, and cost estimation outlined in this
publication are useful for national and local administrators,
engineers, field practitioners, and policy makers.
As global waste generation increases at a rapid rate, there is a
dire need for waste management practices such as collection,
disposal, and recycling to protect from environmental pollution.
However, developing countries generate two to three times more
waste, resort to open dumps more often than developed countries,
and are slower to integrate waste management standards. There is a
need for studies that examine the waste generation and practices of
countries that share similar economic backgrounds as they strive to
implement successful waste management techniques. Sustainable Waste
Management Challenges in Developing Countries is an essential
reference source that discusses the challenges and strategies of
waste management practices and the unique waste issues faced by
developing countries that prevent them from achieving the goal of
integrated waste management. While highlighting topics including
e-waste, transboundary movement, and consumption patterns, this
book is ideally designed for policymakers, legislators, waste
company managers, environmentalists, students, academicians, and
municipal planners seeking current research on the global waste
management problem.
A central concern that has remained relevant in recent years has
been the management of waste and pollution. Improper disposal
methods such as open-air burning and unsafe recycling have led to
significant public and environmental health issues including
respiratory disorders, resource depletion, and infant mortality.
Adopting new waste management techniques is a necessity in order to
preserve the health of the global community and ecosystem. Waste
Management Techniques for Improved Environmental and Public Health
provides innovative insights into the advancing methods and
technologies of reducing pollution and promoting sustainable
development. The content within this publication examines
ecological technologies, risk assessment, and green operation. It
is designed for ecologists, biologists, researchers, enterprises,
academicians, policymakers, scientists, environmental engineers,
and students seeking current research on developing theories and
techniques within waste moderation and environmental protection.
With the advancement of new technologies, existing wastewater
treatment units need to be reexamined to make them more efficient
and to release the load currently placed on them. Thus, there is an
urgent need to develop and adopt the latest design methodology to
determine and remove harmful impurities from water sources.
Advanced Design of Wastewater Treatment Plants: Emerging Research
and Opportunities is a critical scholarly resource that explores
the design of various units of wastewater treatment plants and
treatment technologies that can produce reusable quality water from
wastewater. The book covers topics that include the basic
philosophy of wastewater treatment, designing principles of various
wastewater treatment units, conventional treatment systems, and
advanced treatment processes. It is an integral reference source
for engineers, environmentalists, waste authorities, solid waste
management companies, landfill operators, legislators, researchers,
and academicians.
A rapidly growing population, industrialization, modernization,
luxury life style, and overall urbanization are associated with the
generation of enhanced wastes. The inadequate management of the
ever-growing amount of waste has degraded the quality of the
natural resources on a regional, state, and country basis, and
consequently threatens public health as well as global
environmental security. Therefore, there is an existent demand for
the improvement of sustainable, efficient, and low-cost
technologies to monitor and properly manage the huge quantities of
waste and convert these wastes into energy sources. Innovative
Waste Management Technologies for Sustainable Development is an
essential reference source that discusses management of different
types of wastes and provides relevant theoretical frameworks about
new waste management technologies for the control of air, water,
and soil pollution. This publication also explores the innovative
concept of waste-to-energy and its application in safeguarding the
environment. Featuring research on topics such as pollution
management, vermicomposting, and crude dumping, this book is
ideally designed for environmentalists, policymakers,
professionals, researchers, scientists, industrialists, and
environmental agencies.
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.
