Circular ecologies : environmentalism and waste politics in urban China
After four decades of reform and development, China is confronting a domestic waste crisis. As the world's largest waste-generating nation, the World Economic Forum projects that by 2030, the volume of household waste in China will be double that of the United States. Starting in the early 2000s, Chinese policymakers came to see waste management as an object of environmental governance central to the creation of \"modern\" cities, and experimented with the circular economy, in which technology and policy could convert all forms of waste back into resources. Based on long-term research in Guangzhou, Circular Ecologies critically analyzes the implementation of technologies and infrastructures to modernize a mega-city's waste management system, and the grassroots ecological politics that emerged in response. In Guangzhou, waste's transformation revealed uncomfortable truths about China's environmental governance: a preference for technology over labor, the aestheticization of order, and the expropriation of value in service of an ecological vision.
Amy Zhang argues that in post-reform China, waste—the material vestige of decades of growth and increasing consumption—is a systemic irritant that troubles China's technocratic governance. Waste provoked an unlikely coalition of urban communities, from the middle class to precarious migrant workers, that came to constitute a nascent, bottom-up environmental politics, and offers a model for conceptualizing ecological action under authoritarian conditions.

Recycled Jute Non-Woven Material Coated with Polyaniline/TiOsub.2 Nanocomposite for Removal of Heavy Metal Ions from Water
Growing volumes of textile waste and heavy metal pollution of water are emerging environmental challenges. In an attempt to tackle these issues, a non-woven sorbent based on jute fibers was fabricated by recycling the textile waste from the carpet industry. The influence of contact time, concentration, pH and temperature on the sorption of lead and copper ions from aqueous solutions was studied. In order to enhance the sorption capacity of the non-woven material, in situ synthesis of polyaniline (PANI) in the presence of TiO[sub.2] nanostructures was performed. The contribution of TiO[sub.2] nanoparticles and TiO[sub.2] nanotubes to the uniformity of PANI coating and overall sorption behavior was compared. Electrokinetic measurements indicated increased swelling of modified fibers. FTIR and Raman spectroscopy revealed the formation of the emeraldine base form of PANI. FESEM confirmed the creation of the uniform nanocomposite coating over jute fibers. The modification with PANI/TiO[sub.2] nanocomposite resulted in a more than 3-fold greater sorption capacity of the material for lead ions, and a 2-fold greater absorption capacity for copper ions independently of applied TiO[sub.2] nanostructure. The participation of both TiO[sub.2] nanostructures in PANI synthesis resulted in excellent cover of jute fibers, but the form of TiO[sub.2] had a negligible effect on metal ion uptake.
Journal Article
Waste problems and management in developing countries
\"This new volume offers effective solutions to the mismanagement of waste, particularly in developing countries, by providing an understanding of different types of wastes, their generation, and use of advanced technologies for waste management, and by focusing on integrating the technical and regulatory complexities of waste management. Waste Problems and Management in Developing Countries provides a comprehensive overview of the characterization, issues, and regulatory development of waste management for sustainable solutions and prevention techniques. It covers the various types of pollution, including pollution from plastics, industrial activities, metals, livestock, healthcare, food loss and waste, etc. It explores new techniques for thermal and radioactive waste management and includes such methods as vermicomposting and composting for organic wastes management and profitable use. The volume also looks at the role of modern technologies and legislation measures to manage biosolid waste. The volume includes numerous data sets obtained from various surveys and highlights special categories of waste that may not fit precisely into either RCRA Subtitle D (solid wastes) or Subtitle C (hazardous wastes). Academicians, researchers, and students will find the volume to be a comprehensible volume about waste management and its diversity, exploration, exploitation, and management strategies.\"-- Provided by publisher.
BOOK
An Ontology of Trash
A philosophical exploration of the problematic nature of the disposable.
Plastic bags, newspapers, pizza boxes, razors, watches, diapers, toothbrushes … What makes a thing disposable? Which of its properties allows us to treat it as if it did not matter, or as if it actually lacked matter? Why do so many objects appear to us as nothing more than brief flashes between checkout-line and landfill?
In An Ontology of Trash, Greg Kennedy inquires into the meaning of disposable objects and explores the nature of our prodigious refuse. He takes trash as a real ontological problem resulting from our unsettled relation to nature. The metaphysical drive from immanence to transcendence leaves us in an alien world of objects drained of meaningful physical presence. Consequently, they become interpreted as beings that somehow essentially lack being, and exist in our technological world only to disappear. Kennedy explores this problematic nature and looks for possibilities of salutary change.

From the cult of waste to the trash heap of history : the politics of waste in socialist and postsocialist Hungary
Zsuzsa Gille combines social history, cultural analysis, and
environmental sociology to advance a long overdue social theory of waste in this
study of waste management, Hungarian state socialism, and post--Cold War capitalism.
From 1948 to the end of the Soviet period, Hungary developed a cult of waste that
valued reuse and recycling. With privatization the old environmentally beneficial,
though not flawless, waste regime was eliminated, and dumping and waste incineration
were again promoted. Gille's analysis focuses on the struggle between a
Budapest-based chemical company and the small rural village that became its toxic
dump site.

Recycling Reconsidered
Recycling is widely celebrated as an environmental success story. The accomplishments of the recycling movement can be seen in municipal practice, a thriving private recycling industry, and widespread public support and participation. In the United States, more people recycle than vote. But, as Samantha MacBride points out in this book, the goals of recycling -- saving the earth (and trees), conserving resources, and greening the economy -- are still far from being realized. The vast majority of solid wastes are still burned or buried. MacBride argues that, since the emergence of the recycling movement in 1970, manufacturers of products that end up in waste have successfully prevented the implementation of more onerous, yet far more effective, forms of sustainable waste policy. Recycling as we know it today generates the illusion of progress while allowing industry to maintain the status quo and place responsibility on consumers and local government.MacBride offers a series of case studies in recycling that pose provocative questions about whether the current ways we deal with waste are really the best ways to bring about real sustainability and environmental justice. She does not aim to debunk or discourage recycling but to help us think beyond recycling as it is today.
