In the last ten years (2009-2019), flooding caused the death of over 48,000 people, and affected over 697 million people globally. This is expected to increase as a result of climate change, population growth and urbanisation. Floods can cause infections due to the release of water-borne pathogens from surcharged combined sewers and other sources of faecal contamination on urban surfaces such as concrete, asphalt, gravel, pavement, playground rubber tiles and grass. Using laboratory experiments with faecal indicator bacteria Escherichia coli, and with Bacillus subtilis spores, and MS2 bacteriophages under controlled exposure to simulated sunlight, this research contributes towards a better understanding of the environmental parameters that affect the concentration of pathogens in contaminated shallow water bodies and on different urban surfaces. Also, several sampling methods are assessed for the recovery of bacteria from flood-prone urban surfaces. This study suggests that given the sunlight conditions after an urban flood, the concentration of indicator organisms and of total suspended solids and the surface type it is possible to estimate the fate of selected pathogens. The observations and results presented in this study contribute to the development of policy-making tools for rapid implementation of appropriate measures to mitigate public health risks after flooding. This book: - highlights the relation of urban floods with water-borne diseases. -stresses for the first time the importance of urban surfaces (pavement, concrete, asphalt, etc.) on the inactivation of water-borne pathogens. -provides equations that can be used to develop policy-making tools for implementation of appropriate measures to mitigate public health risks after flooding.

From Waste to Value investigates how streams of organic waste and residues can be transformed into valuable products, to foster a transition towards a sustainable and circular bioeconomy. The studies are carried out within a cross-disciplinary framework, drawing on a diverse set of theoretical approaches and defining different valorisation pathways. Organic waste streams from households and industry are becoming a valuable resource in today's economies. Substances that have long represented a cost to companies and a burden for society are now becoming an asset. Waste products, such as leftover food, forest residues and animal carcasses, can be turned into valuable products such as biomaterials, biochemicals and biopharmaceuticals. Exploiting these waste resources is challenging, however. It requires that companies develop new technologies and that public authorities introduce new regulation and governance models. This book helps policy-makers govern and regulate bio-based industries, and helps industry actors to identify and exploit new opportunities in the circular bioeconomy. Moreover, it provides important insights for all students and scholars concerned with renewable energy, sustainable development and climate change.

Waste is a quintessentially ecological economic issue. The generation of waste is rooted in the very laws of nature, but waste is also a social construct, and what we understand to be waste has evolved with human societies. Therefore, a crucial issue in modern waste management is the understanding of attitudes towards waste. This book examines the ecological economics approach to waste, its conceptualisation and management. In order to provide a comprehensive understanding of the issue of waste, the authors utilise an array of disciplinary approaches from both natural and social sciences. They begin by considering waste through the thermodynamics of production processes, and through an assessment of the history of waste. Building on this physical-social background, they concentrate on specific aspects of waste policy. These include the public's attitude towards waste, the economics of waste, and the laws and regulations surrounding waste disposal. Further chapters look in detail at the three main types of waste being generated by modern societies: municipal, toxic and nuclear waste. This path-breaking book seeks to lay the basis for a general conceptualisation of waste in ecological economics and to elucidate the main issues relating to waste generation and management. This is a comprehensive analysis of waste as a concept, and as an issue for humans as both producers and consumers. It will be of great value to ecological economists, waste managers and environmental policy analysts.

The Politics of Trash explains how municipal trash collection solved odorous urban problems using nongovernmental and often unseemly means. Focusing on the persistent problems of filth and the frustration of generations of reformers unable to clean their cities, Patricia Strach and Kathleen S. Sullivan tell a story of dirty politics and administrative innovation that made rapidly expanding American cities livable. The solutions that professionals recommended to rid cities of overflowing waste cans, litter-filled privies, and animal carcasses were largely ignored by city governments. When the efforts of sanitarians, engineers, and reformers failed, public officials turned to the habits and tools of corruption as well as to gender and racial hierarchies. Corruption often provided the political will for public officials to establish garbage collection programs. Effective waste collection involves translating municipal imperatives into new habits and arrangements in homes and other private spaces. To change domestic habits, officials relied on gender hierarchy to make the women of the white, middle-class households in charge of sanitation. When public and private trash cans overflowed, racial and ethnic prejudices were harnessed to single out scavengers, garbage collectors, and neighborhoods by race. These early informal efforts were slowly incorporated into formal administrative processes that created the public-private sanitation systems that prevail in most American cities today. The Politics of Trash locates these hidden resources of governments to challenge presumptions about the formal mechanisms of governing and recovers the presence of residents at the margins, whose experiences can be as overlooked as garbage collection itself. This consideration of municipal garbage collection reveals how political development often relies on undemocratic means with long-term implications for further inequality. Focusing on the resources that cleaned American cities also shows the tenuous connection between political development and modernization. -- Cornell University Press

The ultimate in recycling, composting has been in use in some form since ancient times. A well-managed composting facility should exist as a good neighbor contributing to ecology. However, since local populations often perceive risks if a composting facility is built nearby, composting facilities must be designed and operated with minimal odor, dust, and noise emissions. Industrial Composting examines the key operational aspects and problems associated with composting, with strong emphasis on odor mitigation, pathogens, and aerosols. Designed for composting professionals and supported by extensive quality references, this book covers: Facilities Planning and Design Odor Management Design, Material, Energy, and Water Balances Economics of Product Marketing and Sales Public Relations, Participation, and Communication Regulations Pathogen Concentrations as Related to Feedstocks Bioaerosols Associated with Composting and Their Potential Diseases While many books cover composting, most of those currently available are either out of date or contain only a few chapters on the subject. With interest growing in the use of composting for biosolids, food wastes, and other specialty areas, the need for an up-to-date, focused resource is also increasing. To assist composting practitioners, community decision makers, and advocates, Industrial Composting brings recent advances and best practices in composting together in an accessible, professional volume.

A bidirectional approach of detoxifying the liquid and gaseous effluents of oil refineries is elucidated in this thesis. Liquid effluents of oil refineries contain selenium oxyanions and phenol, while gaseous effluents contain CO/syngas. To remove the phenol and simultaneously reduce the selenite oxyanions, a fungal-bacterial co-culture of Phanerochaete chrysosporium and Delftia lacustris was developed. Two modes of co-cultures of the fungus and the bacterium were developed. Both cultures were investigated for phenol degradation and selenite reduction. In order to valorize the CO/syngas by bioconversion techniques. an anaerobic methanogenic sludge was acclimatized to use CO as the sole carbon substrate to produce acetic acid, butyric acid, and hexanoic acid. Later, the acids were metabolized at lower pH, producing alcohols ethanol, butanol and hexanol, confirming the successful enrichment strategy. The next experiment focused on the absence of the trace element tungsten, and consecutively selenium on the previously CO acclimatized sludge under the same operating conditions. An in-situ synthesized co-polymeric gel of N-ter-butyl-acrylamide and acrylic acid was used to recover ethanol, propanol and butanol from a synthetic fermentation broth. The scope of repeated use of the gel for alcohol recovery was investigated and 98% alcohol was recovered.
