Resisting Garbage presents a new approach to understanding practices of waste removal and recycling in American cities, one that is grounded in the close observation of case studies while being broadly applicable to many American cities today. Most current waste practices in the United States, Lily Baum Pollans argues, prioritize sanitation and efficiency while allowing limited post-consumer recycling as a way to quell consumers’ environmental anxiety. After setting out the contours of this “weak recycling waste regime,” Pollans zooms in on the very different waste management stories of Seattle and Boston over the last forty years. While Boston’s local politics resulted in a waste-export program with minimal recycling, Seattle created new frameworks for thinking about consumption, disposal, and the roles that local governments and ordinary people can play as partners in a project of resource stewardship. By exploring how these two approaches have played out at the national level, Resisting Garbage provides new avenues for evaluating municipal action and fostering practices that will create environmentally meaningful change.

This book addresses the need for a technical guided thought on production, consumption, and waste management of plastic and polymers in the African continent. Issues such as resource availability, processing technologies, plastic policies, and much more are covered in the book. While Africa is made up of several different countries which might be different from each other in many ways, these countries within the African continent have some commonalities such as region, some shared history, resources, and some shared policies through organizations such as the African Union, African Free trade Zone, and ECOWAS. With a population of over a billion, the African continent has become an attractive market for various businesses. Several publications in recent years have pushed for the advancement of the African continent toward increased manufacturing as a road to development. This inevitably includes the plastics and other polymers industry. Careful consideration must be taken to ensure that this growth will focus on more sustainable and greener manufacturing; otherwise, this anticipated growth in the plastics and polymer industry will only spell increased pollution and worsening of the environment.

Like many industrialized regions, the Philadelphia metro area contains pockets of environmental degradation: neighborhoods littered with abandoned waste sites, polluting factories, and smoke-belching incinerators. However, other neighborhoods within and around the city are relatively pristine. This eye-opening book reveals that such environmental inequalities did not occur by chance, but were instead the result of specific policy decisions that served to exacerbate endemic classism and racism. From Workshop to Waste Magnet presents Philadelphia's environmental history as a bracing case study in mismanagement and injustice. Sociologist Diane Sicotte digs deep into the city's past as a titan of American manufacturing to trace how only a few communities came to host nearly all of the area's polluting and waste disposal land uses. By examining the complex interactions among economic decline, federal regulations, local politics, and shifting ethnic demographics, she not only dissects what went wrong in Philadelphia but also identifies lessons for environmental justice activism today. Sicotte's research tallies both the environmental and social costs of industrial pollution, exposing the devastation that occurs when mass quantities of society's wastes mix with toxic levels of systemic racism and economic inequality. From Workshop to Waste Magnet is a compelling read for anyone concerned with the health of America's cities and the people who live in them.

This book includes data and other pertinent information about CERCLA and the Superfund program, followed by a glossary. EPA defines brownfields as abandoned, idled, or under-used industrial and commercial facilities where expansion or redevelopment is complicated by real or perceived environmental contamination. FY1997 was the first year brownfields became a separate budgetary line item, at $37.7 million. For FY2000 the appropriation was $91.7 million. In the FY2001 budget, the Administration requested and was appropriated $91.6 million. The 106th Congress extended the brownfields cleanup tax incentive to December 31, 2003, and expanded it to make all brownfields certified by a state environmental agency eligible for tax break. Other brownfields bills introduced in the Congress appeared to confirm the general direction EPA has taken. Two Superfund reauthorisation bills were reported in the House, each of which contained a title on brownfields. The history, background and operations of the brownfields are described.
