  • Remediation of hazardous wastes present in the subsurface has evolved with time and has been influenced by various factors over the years. During the early years, direction and efforts were mostly influenced by the regulations in place and the need for compliance and protection of human health and environment. The contaminants primarily focused upon during this time were the petroleum-related contaminants stemming from leaking underground storage tanks (USTs

  • Since the Second World War, and especially since the publication of Rachel Carson’s Silent Spring in 1962, there has been growing concern about contamination of the environment by “man-made” chemicals. These chemicals may be present in industrial and municipal effluents, in consumer or commercial products, in mine tailings, in petroleum products, and in gaseous emissions. Some chemicals such as pesticides may be specifically designed to kill biota present in natural or agricultural ecosystems. They may be organic, inorganic, metallic, or radioactive in nature.

  • Sintering is one of the final stages of ceramics fabrication and is used to increase the strength of the compacted material. In the Sintering of Ceramics section, the fabrication of electronic ceramics and glass-ceramics were presented. Especially dielectric properties were focused on. In other chapters, sintering behaviour of ceramic tiles and nano-alumina were investigated. Apart from oxides, the sintering of non-oxide ceramics was examined.

  • The charge to this committee—to envision the future of geotechnology— is at once a grand challenge and a problem. In many ways, geotechnology is a mature field having come to its majority in the last 50 years. Many serious problems have been solved. We know how to build strong foundations, safe dams, and stable roads and tunnels. We have a good understanding about the behavior and protection of groundwater, how to extract the petroleum resources, and develop a geothermal field.

  • Soil contamination has severely increased over the last decades, mainly due to petroleum hydrocarbons, solvents, pesticides, lead and other heavy metals from industrial wastes and human activities. The critical point regarding contaminated soil monitoring is the intrinsic difficulty in defining fixed monitoring variables and indicators as the establishment of any a priori criterion and threshold for soil quality can be still considered subjective.

  • The use of alternative fuels to displace coal reduces reliance on fossil fuels, reduces emissions of carbon dioxide (CO2) and other pollutants, and contributes to long-term cost savings for cement plants. Further, due to their high burning temperatures, cement kilns are well-suited for accepting and efficiently utilizing a wide range of wastes that can present a disposal challenge. This report begins with an overview of the types of alternative fuels used in cement kilns, focusing on energy and environmental considerations.

  • The following sections provide an overview of the technical and qualitative characteristics of a wide range of alternative fuels that can replace coal in cement kilns. These fuels include agricultural and non-agricultural biomass, chemical and hazardous wastes, petroleum-based wastes, and miscellaneous waste fuels. Each of these alternatives are described in detail, including a discussion of average substitution rates, energy and water content of the fuels, carbon dioxide emissions factors, and change in carbon emissions per ton1 of coal replacement.

  • The pollutants contained in the wash water can include sand, sewage waste, plant materials, oil grease, diesel, dead fish, paper products, soap products and petroleum products. Samples analyzed from 2007-2008 show multiple instances of Total Coliform above 1,600,000 MPN/100ml, Fecal Coliform above 18,755 MPN/100ml, and Enterococcus above 24,196 MPN/100ml, all of which are above the action level determined by the City of Oceanside.

  • In 1993, the U.S. Department of Energy (DOE) Office of Industrial Technology (OIT) established a group of seven industries designated as Industries of the Future (IOF). These industries were selected for their high energy use and large waste generation. The original IOF included the aluminum, chemicals, forest products, glass, metalcasting, petroleum refining, and steel industries. Each industry was asked to provide a future vision and a road map detailing the research required to realize its vision.
