A systematic, global and integration concept is applied upon garbage disposal problem caused by the substantial increase of garbage in China's cities and towns to promote the coordinated development of garbage stations. A kind of echelon pattern of urban circle solid waste disposal is put forward as well as five key technologies which are essential to be used in the pattern. The echelon pattern...

A brief overview is given of the sources, characteristics, and toxic constituents of municipal solid wastes. Several methods are presented for handling, treating, and disposal of solid wastes. Monitoring the landfill site is necessary; there has been a trend to recognize that municipal solid wastes may be hazardous and to provide separate secure handling, treatment, and disposal for their dange...

.Many of the most serious and complex problems facing the United States today result from our phenomenal tech­ nological achievements and. accelerating pace of urbaniza­ tion. The capacity of this nation to produce and consume goods has swelled dramatically, particularly in the two decades since the end of World War II. Within the same period, urban growth has compacted more than half of the to...

there are enormous quantities of unknown composition of hazardous wastes in tehran without any control, safe disposal and treatment. this study was done to identify hazardous wastes and to control this wastes by establishing a treatment, storage and disposal facility. according to available statistics there are 4461 different industries in tehran, out of which sample were chosen each having ove...

The scientific disposal of Municipal Solid Waste (MSW) is of great significance to the urban ecological environment and the residents’ health. Taking into account the economic, technical, environmental, social indicators, as well as their subindicators, analyzing fourteen evaluation factors, the paper discusses four kinds of disposal methods of MSW using AHP and Fuzzy comprehensive evaluation. ...

Municipal Experience with "Pay-As-You-Throw" Policies: Findings From a National Survey Based on a large, nationally representative sample of cities with recycling programs, this study examines whether a Pay-As-You-Throw (PAYT) pricing policy for solid waste collection and disposal service is an incentive for households to change their waste disposal and recycling behaviors. The study finds that...

Based on the Systematic Layout Planning theory and the analysis of transfer stations’ technological processes, a layout optimization model for solid waste transfer and disposal stations was made. The operating units’ layout of the solid waste transfer and disposal stations was simulated and optimized using the genetic algorithm, which could achieve reasonable technological processes, the smalle...

This paper estimates the economic values of household preference for enhanced solid waste disposal services in Malaysia. The contingent valuation (CV) method estimates an average additional monthly willingness-to-pay (WTP) in solid waste management charges of €0.77 to 0.80 for improved waste disposal services quality. The finding of a slightly higher WTP from the generic CV question than that o...

Growth in technology enhances need and utilization of electronic and electrical equipment’s (EEE) everywhere in the world. As a result, e-waste acquires a large share in the conventional solid waste stream. Limited recycling solutions available pushes the need for e-waste disposal solutions. The paper highlights the increasing e-waste pie in solid waste. Various disposal solutions available for...

background and purpose: an appropriate solid waste (sw) disposal has been a major problem in municipal environment. the use of landfills is the most economical and environmentally acceptable method for the disposal of sws all over the world. however, landfill leachate can cause environmental issues such as soil and ground water pollution. so, finding suitable land fill site is one of the most s...
