Uncontrolled growth of the urban population in developing countries in recent years has made solid waste management an important issue. Today municipal solid waste management (MSWM) is one of the most challenging issues in urban cities, which are facing a serious pollution problem due to the generation of huge quantities of solid waste. This results in development of environmentally sustainable...

abstract background: leachate produced by waste disposal sites can be contaminating groundwater. the contamination vulnerability and groundwater protection assessment has proved to be an effective tool for the delineation of protection zones in area affected by groundwater contamination. the main objective of the study is to evaluate aquifer pollution vulnerability in the new waste disposal sit...

municipal solid wastes (msws) vary in terms of quality and quantity, especially their toxic content. the efficient and sound disposal of msws not only needs implementing an integrated management procedure, but also performing a conservative way to reduce the impacts on resources. in the present research, after characterization of msw streams and consideration of disposal methods practiced in si...

Anaerobic decomposition of organic compounds in landfills is responsible for generation of greenhouse gases. The present study aimed to determine the total gas and methane emission from a landfill located in Hamedan (west of Iran) from 2011 to 2030. LandGEM 3.02 model was used to estimate the gas emission with the volumetric methane percent of 60%, production potential of 107, and methane gener...

In almost all cities, the solid waste generation is increased dramatically and becomes a great challenge today to municipal authority for its collection and safe disposal. Continuous uncontrolled generation of solid wastes forces the existing landfills to become exhausted rapidly[2-3]. Other hand the chance of availability of open land for future provision of landfill in a city is now very less...

www.aana.com/aanajournalonline The goal of this project was to optimally sort waste material in the operating room (OR) environment and divert waste such that streams of low-cost disposal, including recyclable material, could be maximized. Using the Lean Six Sigma method, we followed 5 steps to define, measure, analyze, improve, and control. Descriptive statistics were used to describe OR chara...

Oily sludge is one of the most significant solid wastes generated in the petroleum industry. It is a complex emulsion of various petroleum hydrocarbons (PHCs), water, heavy metals, and solid particles. Due to its hazardous nature and increased generation quantities around the world, the effective treatment of oily sludge has attracted widespread attention. In this review, the origin, characteri...

Solid waste represents a key issue that threatens environmental quality in Egyptian urban areas. One of the most viable options to treat such an issue is to incinerate the collected solid waste for electricity generation, which can reduce the cost of solid waste disposal as well as pollution and generate surplus energy. Selecting appropriate site for a solid waste incineration power plant is a ...
