Recycling is the need of the hour and it is an inevitable destination at the end of the life of any product. Today, recycling can happen at postindustrial and post-consumer states and the importance of recycled products in the market has gained significant importance. Recycled products dominate the array of sustainable products in today's context. Even though there are commercial implications for recycling, one of the very important and obvious reasons to go for recycling and to have recycled products is to have the benefits on environmental sustainability. It is highly important to assess the environmental footprints of recycled products and further improve the environmental benefits of such recycled products. This book presents five interesting chapters pertaining to the environmental footprints of various recycled products.

The edited book brings out a comprehensive synthesis of latest scientific literature covering various important aspects of anaerobic biodigesters for human waste management that ranges from latest understanding on fundamental concepts/mechanisms of anaerobic biodigestion, modern tools and techniques used in process evaluation, current strategies being recruited for the performance enhancement, and case studies/ success stories across the world on applications of biodigesters used in human waste treatment. The anaerobic biodigestion is a process of break-down of organic waste by anaerobic microorganisms in absence of the oxygen. This process has been conventionally used for treating various types of organic waste including sewage sludge. After optimizing various process parameters, researchers have developed anaerobic biodigesters that have been successfully used for human waste (nigh soil) treatment. The topic of human waste treatment assumes global significance in the wake of UN sustainable Development Goals (SDG) wherein SDG-6 specifically highlights the Sanitation for all by 2030. The anaerobic Biodigester technology has the potential to manage the human waste as well and can contribute immensely in achieving targets of UN-SDG-6. This book is of interest to researchers, academicians, scientists, policy officials and capacity builders. Also the book serves as additional reading material for undergraduate and graduate students of environmental Biotechnology. National and international biotechnologists, environmental engineers and sanitation experts also find this to be a useful read.

Agriculture and industry are the two most important economic sectors for various countries around the globe, providing millions of jobs as well as being the main source of income for these countries. Nevertheless, with the increasing demand for agricultural and industrial produce, huge amounts of waste are also being produced. Without proper management, this waste (both liquid and solid) poses a serious threat to overall environmental quality, mainly due to its toxicity and slow degradation processes. Current approaches are effective but would normally require huge capital investments, are labour intensive and generate potential hazardous by-products. As such, there is a need for alternative approaches that are cheaper, easier-to-handle and have a minimum potential impact on environmental quality. This book presents up-to-date approaches using biological techniques to manage the abundance of waste generated from agricultural and industrial activities. It discusses techniques such as bioconversion, biodegradation, biotransformation, and biomonitoring as well as the utilization of these wastes. A number of chapters also include individual case studies to enhance readers' understanding of the topics. This comprehensive book is a useful resource for anyone involved in agricultural and industrial waste management, green chemistry or biotechnology. It is also recommended as a reference work for graduate students and all agriculture and biotechnology libraries.

Solid waste management issues, technologies and challenges are dynamic. More so, in developing and transitory nations in Asia. This book, written by Asian experts in solid waste management, explores the current situation in Asian countries including Pacific Islands. There are not many technical books of this kind, especially dedicated to this region of the world. The chapters form a comprehensive, coherent investigation in municipal solid waste (MSW) management, including, definitions used, generation, sustainable waste management system, legal framework and impacts on global warming. Several case studies from Asian nations are included to exemplify the real situation experienced. Discussions on MSW policy in these countries and their impacts on waste management and minimization (if any) are indeed an eye-opener. Undoubtedly, this book would be a pioneer in revealing the latest situation in the Asian region, which includes two of the world's most dynamic nations in the economic growth. It is greatly envisaged to form an excellent source of reference in MSW management in Asia and Pacific Islands. This book will bridge the wide gap in available information between the developed and transitory/developing nations.

This book is based on research and observations undertaken for the author's PhD thesis at the National University of Ireland, and represents a case study of national and regional campaigns against both the Irish state's Regional Waste Management Plans and the corporate sector's attempts to develop waste incinerators or dumps in various parts of Ireland. This book provides an in depth account of the mobilizing patterns and framing processes of community campaigns which emerged in the wake of the Irish state's introduction of regional plans for waste management, which included plans for municipal 'waste to energy' plants or incinerators. It is the only book with a sole focus on this aspect of Irish society during the 'Celtic Tiger' boom which preceded the current economic downturn, and examines policy, population, development social issues and local and national electoral processes in detail at a time of immense change in the Republic of Ireland. As such, it provides a salient insight into the societal shifts which provide opportunities for social movements to oppose state or corporate plans which may be perceived to have human health or environmental risks associated with them.
