Background & Aims of the Study: Increasing hazardous industrial wastes and lack of necessary regulations for management of them have led to serious problems in some parts of Iran. The aim of this study was to evaluate the situation of collection, transportation, recycling, and disposal of hazardous industrial wastes in the Khazra Industrial Park of Kerman, Iran. Materials & Meth...

OBJECTIVES Infected hospital wastes are among hazardous wastes, and special treatment methods are needed for their disposal. Having information about present status of medical waste management systems is of great importance in finding weak, and for future planning. Such studies have not been done for most of the hospitals in Iran. METHODS This paper reports the results of a study on the prese...

The minimization of hazardous waste generation as well as the proper treatment and disposal of generated waste has great importance for the protection of present and future human health and the environment. The purpose of this study was to identify the extent of waste minimization practices carried out by Tennessee waste generators since September 1985, This was accompl i shed methodologically ...

Co-processing of hazardous wastes in cement kilns have for decades been thought to cause increased emissions of PCDD/PCDFs--a perception that has been evaluated in this study. Hundreds of PCDD/PCDF measurements conducted by the cement industry and others in the last few years, on emissions and solid materials, as well as recent test burns with hazardous wastes in developing countries do not sup...

Combustion of wastes is an effective disposal technology. Although there are many examples of application in industry, severe environmental concerns are raised regarding the emissons from incinerators. Thermal treatment plants are usually comprised of a primary combustion chamber followed by a second combustion chamber, as schematically described in Fig. 1. During the oxidation of solid and liq...

Slaughterhouse wastes are a potential reservoir of bacterial, viral, prion and parasitic pathogens, capable of infecting both animals and humans. A quick, cost effective and safe disposal method is thus essential in order to reduce the risk of disease following animal slaughter. Different methods for the disposal of such wastes exist, including composting, anaerobic digestion (AD), alkaline hyd...

More than 167,000 m of mixed waste, waste that contains both chemically hazardous and radioactive components, are in the known inventory at DOE sites that formarly produced nuclear defense materials. The inventory contains both mixed low level wastes (MLLW) and mixed transuranic wastes (MTRU). Site cleanup and decommissioning activities during the coming years are expected to nearly double this...

As the United States continues to increase its dependence on industrial technologies which require hazardous materials and generate hazardous wastes, concern is mounting over the safe transport of hazardous cargo. It is estimated that 1.5 billion tons of hazardous cargo are moved through the nation's transportation systems (excluding pipeline), with truck as the primary mode of transport. Becau...
