Agricultural plastics area significant contributor to solid waste disposal problems, particularly in areas with heavy use of plastic-covered greenhouses or mulch films. Fieldburning and landfilling are no longer viable options for disposal in many areas. Reuse and reduced weight of films are two methods to reduce the amount of material requiring disposal. Recycling, incineration, and on-site de...

Risk assessment has been widely used as a tool for the development of waste management facilities. At the strategic level, risk assessment is used to inform decision makers about the planning process. In terms of a specific site, environmental risk assessment is used to identify risk management options. As an engineering tool, risk assessment is used to optimize the mitigation measures required...

A modified version of the multi-criteria decision aid, ELECTRE III has been developed to account for uncertainty in criteria weightings and threshold values. The new procedure, called ELECTRE-SS, modifies the exploitation phase in ELECTRE III, through a new definition of the pre-order and the introduction of a ranking index (RI). The new approach accommodates cases where incomplete or uncertain...

Cathode ray tube funnel glass is an environmentally problematic relict of old television sets. In particular, landfilling of this material is strongly discouraged because of its high lead content. However, recovery of this toxic lead could prevent its release into the environment and allow its reuse. In this research, lead was separated from the glass matrix by a chloride volatilization process...

In most cases, the anammox process is used for nitrogen removal from reject water coming from dewatering of digested sludge. However, there are more industrial streams suitable for treatment by partial nitritation/anammox process. The landfill leachate may be a good example of such wastewater. Generally, landfilling is the most used solution for treatment of urban solid wastes. The problem with...

EASEWASTE (Environmental Assessment of Solid Waste Systems and Technology) is a new LCA-based decision support tool within waste management. The model, which is developed by the Technical University of Denmark, calculates waste flow, resource consumption and environmental emissions from waste management systems and provides a complete impact assessment in terms of potential global warming, ozon...

abstract in current world environmental and mainly urban wastes are originated mostly from massive human habitat areas, and have caused disturbance, uncomfortable landscape, environmental risks and dissatisfaction. saqqez city with a population of 140000 is one of the largest cities in kurdistan province. due to population increase, consumptions and changes in nutritional habits of people, the ...

Copper flotation waste is an industrial by-product material produced from the process of manufacturing copper. The main concern with respect to landfilling of copper flotation waste is the release of elements (e.g., salts and heavy metals) when in contact with water, that is, leaching. Copper flotation waste generally contains a significant amount of Cu together with trace elements of other tox...

Landfilling although is a popular and economical method of solid waste disposal is associated with the risk of environmental degradation due to inherent problem of leachates. Leachate continues to be of concern especially when it comes into contact with ground water and surface water. Thus a proper treatment of leachate is essential prior to discharge of leachate into surface and subsurface env...
