Biotreatment of industrial effluents
With increasing government regulation of pollution, as well as willingness to levy punitive fines for transgressions, treatment of industrial waste is a important subject. This book is a single source of information on treatment procedures using biochemical means for all types of solid, liquid and gaseous contaminants generated by various chemical and allied industries. This book is intended for practicing environmental engineers and technologists from any industry as well as researchers and professors. The topics covered include the treatment of gaseous, liquid and solid waste from a large number of chemical and allied industries that include dye stuff, chemical, alcohol, food processing, pesticide, pharmaceuticals, paint etc. Information on aerobic and anaerobic reactors and modeling and simulation of waste treatment systems are also discussed. * Compares chemical and biochemical means of industrial waste treatment* Provides details of technology (i.e. reactors, operating conditions etc) with regard to the biochemistry aspects.* Can be used as a teaching aid for graduate courses and a reference material by practicing environmental scientists and engineers.* Researchers can extract synergy between treatment procedures and various effluents.

Innovations and techno-ecological transition
\"This book aims to present a systemic perspective to energetic transition to a discarbonated society implying an increase of energetic efficiency of current production process, new way of energy production -- integration of renewable energies, re-use of wastes. Main societal functions are analyzed in order to highlight the ongoing process of technological and non-technological innovations: transport and mobility, food, building. The purpose of this book is to analyze from a global perspective the energetic innovative system on building and to understand the limits of its development and potential new actions.\" -- Publisher's website.

Cycling and recycling
Technology has long been an essential consideration in public discussions of the environment, with the focus overwhelmingly on creating new tools and techniques. In more recent years, however, activists, researchers, and policymakers have increasingly turned to mobilizing older technologies in their pursuit of sustainability. In fascinating case studies ranging from the Early Modern secondhand trade to utopian visions of human-powered vehicles, the contributions gathered here explore the historical fortunes of two such technologies—bicycling and waste recycling—tracing their development over time and providing valuable context for the policy successes and failures of today.

Deceit and denial
Deceit and Denial details the attempts by the chemical and lead industries to deceive Americans about the dangers that their deadly products present to workers, the public, and consumers. Gerald Markowitz and David Rosner pursued evidence steadily and relentlessly, interviewed the important players, investigated untapped sources, and uncovered a bruising story of cynical and cruel disregard for health and human rights. This resulting exposé is full of startling revelations, provocative arguments, and disturbing conclusions--all based on remarkable research and information gleaned from secret industry documents. This book reveals for the first time the public relations campaign that the lead industry undertook to convince Americans to use its deadly product to paint walls, toys, furniture, and other objects in America's homes, despite a wealth of information that children were at risk for serious brain damage and death from ingesting this poison. This book highlights the immediate dangers ordinary citizens face because of the relentless failure of industrial polluters to warn, inform, and protect their workers and neighbors. It offers a historical analysis of how corporate control over scientific research has undermined the process of proving the links between toxic chemicals and disease. The authors also describe the wisdom, courage, and determination of workers and community members who continue to voice their concerns in spite of vicious opposition. Readable, ground-breaking, and revelatory, Deceit and Denial provides crucial answers to questions of dangerous environmental degradation, escalating corporate greed, and governmental disregard for its citizens' safety and health. After eleven years, Markowitz and Rosner update their work with a new epilogue that outlines the attempts these industries have made to undermine and create doubt about the accuracy of the information in this book.

The global environmental injustice of fast fashion
Fast fashion, inexpensive and widely available of-the-moment garments, has changed the way people buy and dispose of clothing. By selling large quantities of clothing at cheap prices, fast fashion has emerged as a dominant business model, causing garment consumption to skyrocket. While this transition is sometimes heralded as the “democratization” of fashion in which the latest styles are available to all classes of consumers, the human and environmental health risks associated with inexpensive clothing are hidden throughout the lifecycle of each garment. From the growth of water-intensive cotton, to the release of untreated dyes into local water sources, to worker’s low wages and poor working conditions; the environmental and social costs involved in textile manufacturing are widespread.
In this paper, we posit that negative externalities at each step of the fast fashion supply chain have created a global environmental justice dilemma. While fast fashion offers consumers an opportunity to buy more clothes for less, those who work in or live near textile manufacturing facilities bear a disproportionate burden of environmental health hazards. Furthermore, increased consumption patterns have also created millions of tons of textile waste in landfills and unregulated settings. This is particularly applicable to low and middle-income countries (LMICs) as much of this waste ends up in second-hand clothing markets. These LMICs often lack the supports and resources necessary to develop and enforce environmental and occupational safeguards to protect human health. We discuss the role of industry, policymakers, consumers, and scientists in promoting sustainable production and ethical consumption in an equitable manner.

Emerging environmental health risks associated with the land application of biosolids: a scoping review
Background
Over 40% of the six million dry metric tons of sewage sludge, often referred to as biosolids, produced annually in the United States is land applied. Biosolids serve as a sink for emerging pollutants which can be toxic and persist in the environment, yet their fate after land application and their impacts on human health have not been well studied. These gaps in our understanding are exacerbated by the absence of systematic monitoring programs and defined standards for human health protection.
Methods
The purpose of this paper is to call critical attention to the knowledge gaps that currently exist regarding emerging pollutants in biosolids and to underscore the need for evidence-based testing standards and regulatory frameworks for human health protection when biosolids are land applied. A scoping review methodology was used to identify research conducted within the last decade, current regulatory standards, and government publications regarding emerging pollutants in land applied biosolids.
Results
Current research indicates that persistent organic compounds, or emerging pollutants, found in pharmaceuticals and personal care products, microplastics, and per- and polyfluoroalkyl substances (PFAS) have the potential to contaminate ground and surface water, and the uptake of these substances from soil amended by the land application of biosolids can result in contamination of food sources. Advanced technologies to remove these contaminants from wastewater treatment plant influent, effluent, and biosolids destined for land application along with tools to detect and quantify emerging pollutants are critical for human health protection.
Conclusions
To address these current risks, there needs to be a significant investment in ongoing research and infrastructure support for advancements in wastewater treatment; expanded manufacture and use of sustainable products; increased public communication of the risks associated with overuse of pharmaceuticals and plastics; and development and implementation of regulations that are protective of health and the environment.
