Presently in India, about 960 million tonnes of solid waste is being generated annually as by-products during industrial, mining, municipal, agricultural and other processes. Of this 350 million tonnes are organic wastes from agricultural sources; 290 million tonnes are inorganic waste of industrial and mining sectors and 4.5 million tonnes are hazardous in nature. Advances in solid waste manag...
In the recent past, household hazardous waste has become an issue to more and more communities. In an effort to control the pollution generated within a household, various methods have been set forth in col lecting and disposing of these wastes. Unfortunately, all too often the hazardous waste collection days are poorly attended, and the costs become prohibitive when measured against the amoun...
The disposal of hazardous wastes creates major economic and environmental problems for both developed and developing nations. One productive use of hazardous wastes is to blend them into fuel, which mitigates damage to the environment by recycling waste into fuel and reducing fossil-fuel consumption. Operations personnel face a daunting task of efficiently blending hazardous waste into fuel, wh...
This study presents a cost-minimization model for a multi-time-step, multi-type hazardous-waste reverse logistics system. A discrete-time linear analytical model is formulated that minimizes total reverse logistics operating costs subject to constraints that take into account such internal and external factors as business operating strategies and governmental regulations. Application cases are ...
This report examines opportunities for the application of economic incentive instruments for the management and reduction of hazardous wastes. The analysis concludes that as long as firms comply with existing regulations and bear potential tort liability, no additional incentives appear to be warranted. There may be significant residual external damages, however, if full compliance cannot be en...
Equity issues have led many economists to re-consider their preference for conducting efficiency analyses with aggregated estimates of the benefits and costs of changes in environmental resource allocations. For instance, there is evidence that health risks due to hazardous wastes disproportionately affects the poor and non-white. Policies that lead to these disproportionate effects are not nec...
The management of discarded treated wood products upon disposal is one of the many factors that should be considered when evaluating a new wood preservative or when comparing wood preservatives as part of a life cycle assessment. Future environmental ramifications of disposal, as well as regulatory requirements and costs, must be assessed and weighed. This paper presents an overview of the fact...
BACKGROUND This commentary evolved from a workshop sponsored by the National Institute of Environmental Health Sciences titled "Superfund Contaminants: The Next Generation" held in Tucson, Arizona, in August 2009. All the authors were workshop participants. OBJECTIVES Our aim was to initiate a dynamic, adaptable process for identifying contaminants of emerging concern (CECs) that are likely t...
In past two decades waste management has become one of the most important public concern in developing countries. Hospital waste management has become a critical issue as it poses potential health risks and damage to environment. All those wastes which are generated in hospitals or during health care activities carries a higher risk for infection and injury than any other wastes. In the process...
The use of plasma arc technologies, especially in the treatment of hazardous wastes, is set to expand. The technology is intermediate within the waste management hierarchy and is characterised as an Advanced Conversion Technique (ACT) with Best Available Technique (BAT) attributes. Adoption is driven by the increasing stringency of environmental regulations, the requirement for efficient resour...
