Book Description
Landfilling, one of the prevailing worldwide waste management strategies, is presented together with its benefits and environmental risks. Aside from biogas, another non-avoidable product of landfilling is landfill leachate, which usually contains a variety of potentially hazardous inorganic and organic compounds. It can be treated by different physico-chemical and biological methods and their combinations. The composition and characteristics of landfill leachate are presented from the aspect of biotreatability. The treatment with activated sludge, mainly consisting of bacterial cultures under aerobic and anaerobic conditions in various reactor systems, is explained, including an extensive literature review. The potential of fungi and their extracellular enzymes for treatment of municipal landfill leachates is also presented, with a detailed review of the landfill leachate treatment studies. The future perspectives of biological treatment are also discussed.

Book Description
Masters Theses in the Pure and Applied Sciences was first conceived, published, SIld disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all con cerned if the printing and distribution of the volumes were handled by an interna and broader dissemination. tional publishing house to assure improved service Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Cor poration of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 30 (thesis year 1985) a total of 12,400 theses titles from 26 Canadian and 186 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this important annual reference work.

Book Description
In chapter one by Antoine P Trzcinski, Ph.D., a simulated Organic Fraction of Municipal Solid Waste (OFMSW) was treated in an anaerobic two-stage membrane process in order to develop and optimise said process, effectively allowing for improvement upon the current performances obtained with single stage designs. In chapter two, Huu Tap Van and Van Tuyen Trinh present a study with the intent to improve current methods of removal of organic compounds from landfill leachate by Peozone. In chapter three by Hamidi Abdul Aziz and Hossein Farraji, main hazardous compounds of LL and their expected effects on the environment are introduced, as well as plant-based treatment methods. Next, chapter four by Adekunle A Bakare, Chibuisi G Alimba, Titilayo Hassan, Ebenezer O Ajayi, and Akindayo A Sowunmi explores the 96 h median lethal toxicity and cytogenotoxicity of a sawmill wood leachate from a sawmill dumpsite at Ibadan, Nigeria in Clarias gariepinus were investigated, providing further research on the DNA damaging potential of sawmill wood leachate (SWL) in aquatic vertebrates.

Book Description
This book presents new application processes in the context of anaerobic digestion (AD), such as phosphorus recovery, microbial fuel cells (MFCs), and seaweed digestion. In addition, it introduces a new technique for the modeling and optimization of AD processes. Chapters 1 and 2 review AD as a technique for converting a range of organic wastes into biogas, while Chapter 3 discusses the recovery of phosphorus from anaerobically digested liquor. Chapters 4 and 5 focus on new techniques for modeling and optimizing AD. Chapters 6 and 7 then describe the state of the art in AD effluent treatment. The book’s final three chapters focus on more recent developments, including microbial fuel cells (MFCs) (Chapter 8), seaweed production (Chapter 9), and enzyme technologies (Chapter 10).

Book Description
Sanitary Landfilling: Process, Technology, and Environmental Impact is a collection of essays that discusses the role of landfilling in solid waste management. The book presents the approach in the principles of landfilling and the basic biochemical processes in landfills. The text describes the landfill hydrology and leachate production. It discusses the design and construction of liner systems and the surface capping with natural liner materials. The section that follows describes the soil and refuse stability in sanitary landfills. The book will provide valuable insights for engineers, environmentalists, students, and researchers in the field of solid waste management.

Book Description
This book gives an overview of recent findings on the mitigation of gas emission from landfills and sludge processing. Special attention is given to methane and the migration of POPs, heavy metal ions, ammonia and nitrate from landfills to the water-soil system and to the atmosphere. Strategies for mitigating the impact of pollution on ecosystems a

Book Description
The anaerobic process is considered to be a sustainable technology for organic waste treatment mainly due to its lower energy consumption and production of residual solids coupled with the prospect of energy recovery from the biogas generated. However, the anaerobic process cannot be seen as providing the ‘complete’ solution as its treated effluents would typically not meet the desired discharge limits in terms of residual carbon, nutrients and pathogens. This has given impetus to subsequent post treatment in order to meet the environmental legislations and protect the receiving water bodies and environment. This book discusses anaerobic treatment from the perspective of organic wastes and wastewaters (municipal and industrial) followed by various post-treatment options for anaerobic effluent polishing and resource recovery. Coverage will also be from the perspective of future trends and thoughts on anaerobic technologies being able to support meeting the increasingly stringent disposal standards. The resource recovery angle is particularly interesting as this can arguably help achieve the circular economy. It is intended the information can be used to identify appropriate solutions for anaerobic effluent treatment and possible alternative approaches to the commonly applied post-treatment techniques. The succeeding discussion is intended to lead on to identification of opportunities for further research and development. This book can be used as a standard reference book and textbook in universities for Master and Doctoral students. The academic community relevant to the subject, namely faculty, researchers, scientists, and practicing engineers, will find the book both informative and as a useful source of successful case studies.
