Source separation, recycling, combustion, and bene­ ficial use of ash residues are important components of plans for management of household and commercial wastes in order to minimize the cost and risks of landfilling. Municipal incinerators, originally built to avoid unsanitary landfills, are now becoming efficiently operated power plants. However, in order to obtain permits to build and opera...

Landfilling, as a system to discard municipal waste, is still widely used in the tropics, often without appropriate protection against pollution of its surroundings. Leachate generation from landfills, and its chemical composition, varies widely and is significantly influenced by landfill geometry, the type and age of waste, seasonal precipitation, moisture and temperature. In the tropics, clim...

landfill gas is generated by organic waste decomposing under anaerobic conditions. landfill gas contributes to the emission in the atmosphere of greenhouse gases and causing global warming. humidity of environment is an effective parameter on rate of gas generation in landfills. saravan landfill is investigated as study area in this research. it located in 20 kilometers of rasht-tehran highway....

While Brazilian municipal solid waste (MSW) is most often being collected and disposed off at “controlled” dumps and landfills, a large amount of refuse still ends up at irregular dumping sites. Unfortunately, there are few cases where waste is processed in a manner that provides additional benefits to local communities, for example, recovering energy from waste. The most common form of energy ...

A life cycle assessment was carried out to assess a selection of the factors influencing the environmental impacts and benefits of incinerating the fraction of municipal waste remaining after source-separation for reuse, recycling, composting or anaerobic digestion. The factors investigated were the extent of any metal and aggregate recovery from the bottom ash, the thermal efficiency of the pr...

New York state recently passed a food waste (FW) disposal ban, which will prohibit landfilling of FW produced by commercial entities generating more than 2 tons/week the year 2022. This redirect 370,000 tons/year from landfills. In this work, we investigate three questions about landfill ban: 1) How can be diverted to treatment facilities at lowest system cost? 2) To what degree an expanded ana...
