  • Municipal waste consists of everyday items that we use and then throw away, such as product packaging, grass clippings, furniture, clothing, bottles, food scraps, newspapers, appliances, paint, and batteries, which comes from our homes, schools, hospitals, and businesses. Industrial hazardous waste is waste from industrial practices that causes a threat to human or environmental health. As waste generation increases with population expansion and industrialization, waste disposal has become a global challenge for both the developed and developing countries....

  • Sustainability in natural systems is built on the closed-end process of recycling materials. Our present society produces so much that is not recyclable, like resin-molded chairs and air polluting automobile tires, that it is necessary to apply intention to source reduction and product responsibility. Chapter 18 provides knowledge of municipal solid waste and how to disposal and recovery.

  • Hydraulic conductivity is the most important property of geological formations as the flow of fluids and movement of solutes depend on it. Among fluids, water and contaminant migration beneath, the ground surface have become critical for water resource development, agriculture, site restoration and waste disposal strategies.

  • Landfills are excavated or engineered sites where non-liquid hazardous waste is deposited for final disposal and covered. These units are selected and designed to minimize the chance of release of hazardous waste into the environment. Design standards for hazardous waste landfills require a double liner; double leachate collection and removal systems (LCRS); leak detection system; run on, runoff, and wind dispersal controls; construction quality assurance (CQA) program. Liquid wastes may not be placed in a hazardous waste landfill.

  • Batteries are generally galvanic cells which convert chemical energy into electrical energy. As mobile sources of energy, we can no longer imagine life in the modern world without them. Every year in Germany, approximately 1 billion portable batteries are sold, an equivalent of around 30,000 tons (Table 19.1). We can state that 85% of the battery market comprises non-rechargeable primary batteries and 15% rechargeable secondary batteries.

  • The Department of Energy's Office of Environmental Management (DOE-EM) is responsible for cleaning up radioactive waste and environmental contamination resulting from five decades of nuclear weapons production and testing. A major focus of this program involves the retrieval, processing, and immobilization of waste into stable, solid waste forms for disposal. This report, which was requested by DOE-EM, examines requirements for waste form technology and performance in the cleanup program.

  • About 155,000 cubic meters of waste contaminated with both radioactive isotopes and hazardous chemicals are stored at some 30 DOE sites, and another 450,000 cubic meters are buried. While DOE is making a concerted effort to properly dispose of this waste, the amount translates to a multi-decade effort that will require handling, characterizing, and shipping hundreds of thousands of waste containers at a total cost of billions of dollars. This report describes basic scientific research that can lead to new technologies for performing these tasks more safely and cost effectively....

  • Engineered barriers to isolate potentially harmful waste from humans and ecosystems have been used for over 35 years, and much has been written about them and their constituent components. However, few reports have provided an overall assessment of the performance of engineered barrier systems. The last broad assessment was conducted in 1995 (Rumer and Mitchell, 1995). Since that time, new materials and sensor technologies have been introduced and models to predict contaminant transport have improved.

  • The "paperless office" theory went something like this: people would store their information on disks and computers instead of using file folders and paper. As a result, paper use would decrease. This was supposed to help preserve natural resources as well as reduce the world's solid-waste disposal problem.

  • On average, one ton of hazardous waste per person is generated annually by industries in the United States. Before the Resource Conservation and Recovery Act of 1984, hazardous wastes were improperly disposed of into the environment without any regulation. As a result, remediation of these contaminated sites and management of the ongoing hazardous waste sources are two major tasks to be achieved by treatment technologies.

  • Visiting a nice lake is like going to a grocery store that has everything. But what happens if the lake is lacking an item or two? Maybe one or more lake projects can address the need. Although this book has several hundred project ideas, many of them are updated project ideas that have been previously conducted one way or another. For example, dredging has been occurring for over 4000 years. Fish culture, aquatic plant management (using handpulling techniques), and waste disposal are also thousands of years old....

  • The world faces serious difficulties in obtaining the energy that will be needed in coming decades for a growing population, especially given the problem of climate change caused by fossil fuel use. This book presents a view of nuclear energy as an important carbon-free energy option. It discusses the nuclear fuel cycle, the types of reactors used today and proposed for the future, nuclear waste disposal, reactor accidents and reactor safety, nuclear weapon proliferation, and the cost of electric power.

  • Wastes are materials generated as a result of numerous anthropic activities and should be disposed to prevent environmental pollution which aff ects human health and contributes ecosystem degradation. Most of the environmental problems, which we are dealing with, are a result of improper management of wastes. In particular, fresh water resources are under serious stress throughout the globe. Water supply and water quality degradation are global concerns.
