The exponential growth of urban settings has led to an increase in
pollutants and waste management issues around the world. As the
environment continues to falter under the weight of these pressing
issues, it has become increasingly imperative to develop new
technologies and methodologies that have the potential to improve
the overall sustainability and cleanliness of these cities. Smart
Cities as a Solution for Reducing Urban Waste and Pollution
examines emergent research on smart innovations within built urban
environments. Featuring best practices and theoretical frameworks,
as well as potential issues in the implementation of smart and
green technology in urban settings, this publication is a vital
reference source for graduate students, researchers, academics,
engineers, architects, facility managers, and government officials.
Today we can predict storms, reuse wastewater, and desalinate
inland waters. And while technology makes it easier to quickly
communicate, it can also strip away our humanity. Rather than
succumb to the pull of anonymity created by that same technology,
this book was written to help blur the lines between the experts
and the public they affect. It means the experts never forgetting
there are real people trusting them that the water is indeed "safe"
to swim in or the wastewater can be treated to a level safe enough
to drink. It means the public recognizing that operators must fix a
main break no matter when it occurs. It means bringing the public
into the mix upstream, at the discovery point of the problem rather
than waiting to hand them only the preferred solution. No longer is
lifting the experts' curtain only when they're ready to
theatrically reveal solutions acceptable. Gone are the days when
the public trusts all of the negotiations, problem solving, and
hidden props appearing after the production of the water experts is
complete. For the one thing you can predict about us humans is that
hidden beneath the facade of logic, is our deep-seated emotional
side. For only with a solid understanding of the consumer's hidden
world of perceptions and irrationality, can we truly communicate
the value of water. This book reveals the power of engaging the
public when communicating the value of water when it involves
wastewater, stormwater and watersheds. Through stories of success
and why communications can fail, this book is written for
wastewater utilities, watershed stewards and stormwater managers,
engineers, operators, stakeholders, elected officials, and anyone
that truly wants to make a difference in the public's perception
when it comes to the value of water.
The notion of a lifestyle system leading to zero waste is obviously
appealing, and a strategy of total reuse and recycling of: waste
material is often advocated. However, there is a growing
realization that the recycling process itself produces waste, and
the environmental and economic cost of recycling and reusing
certain materials invalidates the zero waste approach as a
universally viable solution. Thus, solutions must be found to deal
with the part of waste that it is not practicable to recycle or
reuse. The energy content of municipal waste (whether raw or
classified) is about 10MJ kg-1. If the total amount of waste
material in any region is around 30 million tons per year or about
1000 kg/ s, the total energy is thus 10,000MJ /s = 10,000 MW. At an
electricity generation efficiency of 20%, this could provide 2000
MW plus about 6000MWof district heating. This energy source is
largely biomass, which is carbon dioxide neutral, and thus does not
contribute to the total atmospheric greenhouse gases. The present
work includes many aspects of municipal solid waste combustion,
such as the effects of moisture, particle size and ash content
effects on solid particle during process rates (moisture
evaporation, volatile release, and char burning rate). The COMMENT
code has developed to reveal much detailed information on the
combustion processes. Through experimental and numerical
investigations, the combustion process of simulated MSW in bed can
be better understood and the experiment results can be used to
amend the mathematics model and be consulted by the application in
the project. The results from modeling can show the combustion
process, and make us deeply know how the heat transfers in the fuel
and gas yields from fuel. At the same time, the simulation can
predict the maximum temperature of waste incineration and the trend
concerning combustion.
Bioremediation is an emerging field of environmental research. The
objective of a bioremediation process is to immobilize contaminants
(reactants) or to transform them into chemical products that do not
pose a risk to human health and the environment. Toxicity and Waste
Management Using Bioremediation provides relevant theoretical and
practical frameworks and the latest empircal research findings on
the remediation of contaminated soil and groundwater using
bioorganisms. Focusing on effective waste treatment methodologies
and management strategies that lead to improved human and
environmental health, this timely publication is ideal for use by
environmenal scientists, biologists, policy makers, graduate
students, and scholars in the fields of environmental science,
chemistry, and biology.
Sustainability is a growing area of research in ecology, economics,
environmental science, business, and cultural studies.
Specifically, sustainable waste disposal and management is a
growing concern as both solid and liquid wastes are rapidly
expanding in direct correlation with population growth and improved
economic conditions across regions. The Handbook of Research on
Waste Management Techniques for Sustainability explores the topic
of sustainable development in an era where domestic and municipal
waste is becoming a concern for both human and environmental
health. Highlighting a number of topics relating to pollution,
green initiatives, and waste reduction in both the public and
private sector, this research-based publication is designed for use
by environmental scientists, business executives, researchers,
graduate-level students, and policymakers seeking the latest
information on sustainability in business, medicine, agriculture,
and society.
Energy costs are a large portion of the operational budget for
water and wastewater utilities, second only to staffing. This
handbook provides information and insight into energy management
strategies that can reduce operational costs, increase operational
efficiencies, and develop a more sustainable infrastructure.
Following the popular plan-do-act-check framework, this book
provides an overview of key steps in developing and implementing an
energy management program. The importance of establishing an energy
team, benchmarking energy use, performing audits, and using
economic analysis tools to prioritize is discussed. The authors
also summarize the wide variety of management measures that can be
used to reduce energy use and associated costs, including
operational improvements, water efficiency strategies, and asset
management programs. Paying particular attention to pumping, the
book describes how motor assessment and maintenance can improve
energy efficiency. Renewable energy options--solar, wind, and
microhydro technologies-are discussed as are external funding
sources and innovative financing methods including energy
performance contracting and leasing options.

Electrical and electronic waste is a growing problem as volumes are
increasing fast. Rapid product innovation and replacement,
especially in information and communication technologies (ICT),
combined with the migration from analog to digital technologies and
to flat-screen televisions and monitors has resulted in some
electronic products quickly reaching the end of their life. The EU
directive on waste electrical and electronic equipment (WEEE) aims
to minimise WEEE by putting organizational and financial
responsibility on producers and distributors for collection,
treatment, recycling and recovery of WEEE. Therefore all
stakeholders need to be well-informed about their WEEE
responsibilities and options. While focussing on the EU, this book
draws lessons for policy and practice from all over the world. Part
one introduces the reader to legislation and initiatives to manage
WEEE. Part two discusses technologies for the refurbishment,
treatment and recycling of waste electronics. Part three focuses on
electronic products that present particular challenges for
recyclers. Part four explores sustainable design of electronics and
supply chains. Part five discusses national and regional WEEE
management schemes and part six looks at corporate WEEE management
strategies. With an authoritative collection of chapters from an
international team of authors, Waste electrical and electronic
equipment (WEEE) handbook is designed to be used as a reference by
policy-makers, producers and treatment operators in both the
developed and developing world.
Advanced oxidation technologies (AOTs) oxidize a broad range of
contaminants, including those that are not readily removed with
other advanced technologies. The need to treat an ever expanding
range of regulated and emerging contaminants has led to an
increased interest in AOTs. This handbook provides the fundamentals
of the design and operation for advanced oxidation technologies.
The possible applications-micropollutant treatment, treatment of
taste and odor compounds, and water reuse treatment-as well as the
advanced oxidation types are covered. The authors look at AOT
facilities including possible locations, key design criteria, and
start-up, operation and maintenance. They also cover equipment
basics and the safety and handling of AOT equipment. Case studies
and considerations for water utility managers such as using an
engineering firm vs going it alone are particularly valuable for
the beginner as well as the more advanced operator.
