This book covers a broad group of wastes, from biowaste to hazardous waste, but primarily the largest (by mass and volume) group of wastes that are not hazardous, but also are not inert, and are problematic for three major reasons: (1) they are difficult to manage because of their volume: usually they are used in civil engineering as a common fill etc., where they are exposed to environmental conditions almost the same way as at disposal sites; (2) they are not geochemically stable and in the different periods of environmental exposure undergo transformations that might add hazardous properties to the material that are not displayed when it is freshly generated; (3) many designers and researchers in different countries involved in waste management are often not aware of time-delayed adverse environmental impact of some large-volume waste, and also do not consider some positive properties that may extend the area of their environmentally beneficial application.

Solid waste has grown into a relatively difficult problem to solve for those responsible for its management; these responsibilities include the collection, transport, treatment, and disposal of solid wastes, particularly wastes generated in medium and large urban centres. This problem is even more intense in economically developing countries, where the financial, human, and other critical resources are scarce in general. In the last decade, there has been a great interest and awareness regarding the environmentally safe management of waste worldwide, centralised in legislative, administrative, standardisation, and research activities in this field. Therefore, it is essential to develop short- and long-term waste management strategies (often named the 3Rs) and their consequent implementation in compliance with the formulated priorities for waste: (1) Reduce, (2) Recycle, (3) Reuse and (4) environmentally safe disposal. Several contradictions and lack of agreement still exist, even regarding the major basic definitions, e.g., which material should be treated as "waste" and which as a "beneficial raw material", which wastes are "hazardous" and which are "non-hazardous", etc. Quite often, different approaches and as a consequence, waste management/disposals are adopted for the same situation/materials. Environmental risk assessment procedures and mode of actions are varied greatly not only within national levels, but also at regional levels within the same country by different groups of scientists and/or policy makers. The general idea of the book has arisen from the mutual experience of many specialists in numerous disciplines from different countries involved in the problem of environmental assessment, economic and monitoring approaches, and control approaches for chemicals generated from solid waste disposal. Solid waste worldwide issues nowadays reflect the complexity and unbalanced development of our world at the beginning of the 21st century. This book covers a broad group of wastes, from biowaste to hazardous waste. The contributors to the book are recognised experts in the diverse fields associated with the issues of waste management and the reuse-recycle of materials, and are from different parts of the world. Authors present their experience and approaches considering both international and national/local specifics. The book is addressed to the wide range of end-users, decision-makers and professionals involved in environmental and agricultural issues: administration, designers, manufacturers, policy makers, farmers, researchers, academics and university students, and is focused on waste properties, environmental behaviour and management in an environmentally safe way. It was not the intention of the editor/authors to exhaust the subject, which is intensely broad, but to give a general idea with updating trends in the field of solid waste management concerning disposal, monitoring, assessment and remedial options, which are demonstrated also in case studies. The authors hope that this book to some extent will contribute to the trials and efforts for the proper, environmentally safe practices of solid waste disposal, and will provide state-of-the-art information and discussion, monitoring strategies, advanced approaches and methods, techniques and equipment for environmentally safe disposal and remediation of solid wastes.
This book introduces a variety of treatment technologies, such as physical, chemical, and biological methods for the treatment of gas emissions, wastewater, and solid waste. It provides a useful source of information for engineers and specialists, as well as for undergraduate and postgraduate students, in the areas of environmental science and engineering.
As global populations continue to increase, the application of biotechnological processes for disposal and control of waste has gained importance in recent years.

It combines biotechnological procedures, sophisticated modeling, and techno-economic analysis of waste, and examines the current need for the maximum recovery of energy from wastes as well as the associated biotechnological and environmental impacts. Features: Presents numerous waste management practices and methods to recover resources from waste using the best biotechnological approaches available. Addresses the challenges, management, and policy issues of waste management and WTE initiatives. Includes practical case studies from around the world. Serves as a useful resource for professionals and students involved in cross-disciplinary and trans-disciplinary research programs and related courses. Discusses the economic and regulatory contexts for managing waste. This book will serve as a valuable reference for researchers, academicians, municipal authorities, government bodies, waste managers, building engineers, and environmental consultants requiring an understanding of waste management and the latest WTE technologies.
Solid waste management is currently a major issue worldwide with numerous areas reaching critical levels. Many developing countries and countries in transition still miss basic waste management infrastructure and awareness. It is here that many of the solid waste management problems and challenges are currently being faced. As such, waste-to-energy (WTE) consists of a proven and continuously developing spectrum and range of technologies in a number of (mostly) developed countries. However, it’s integration in developing countries and systems in transition is often faced with scepticism and a complex set of barriers which are quite unique and differ greatly from those where WTE has been validated and applied over the years. Waste-to-Energy: Opportunities and Challenges for Developing and Transition Economies will address this issue both theoretically and using concrete examples, including: · contributions from numerous scholars and practitioners in the field, · useful lessons and rules of thumb, · both successful and failed cases, and · real-life examples and developments. Waste-to-Energy approaches this dynamic aspect of environmental engineering and management in a methodical and detailed manner making it an important resource for SWM planners and facility operators as well as undergraduate and post graduate students and researchers.
Environmental engineering has a leading role in the elimination of ecological threats, and can deal with a wide range of technical and technological problems due to its interdisciplinary character. It uses the knowledge of the basic sciences biology, chemistry, biochemistry and physics to neutralize pollution in all the elements of the environm

Pesticides in a Changing Environment: Impact, Assessment, and Remediation covers compounds that repel, kill or to prevent any pest. On the basis of the target killed, pesticides are mainly classified as herbicides, fungicides and insecticides. The increased demand of food on account of population explosion has compelled man to use pesticides for better crop production. However, there are many negative impacts of these chemical agrochemicals like toxicity to non-target organisms and retention in bio-systems in the form of their residues, leading to harmful effects on the food chain and food web.This book will be an important source of information for researchers and academicians working in the field of pesticide pollution, its physiology and biochemistry, and development of pesticide remediation technologies. - Assists readers in developing new strategies to address the issues related to sensing and remediation activities - Includes low cost materials for sensor and adsorbent development, allowing professionals to make decisions-based on economic considerations - Provides alternatives for the development of socioeconomically sustainable products for sensing and remediation application
