The outcome is valuable goods, such as high-calorific RDF, as well as non-combustible fractions. The challenge: Turning solid waste into a valuable energy source Due to changing environmental legislation and the need for alternative fuels, new designs for mechanical and biological treatment of municipal solid waste (MSW) and of commercial and. The low calorific value of the waste is due to the presence of a large organic fraction ( per cent), ash and fine earth ( per cent), paper ( per cent) and plastic, glass and metals (each less than one per cent), says a Central Pollution Control Board report. Refuse-derived fuel (RDF) is a fuel produced from various types of waste such as municipal solid waste (MSW), industrial waste or commercial waste.. The World Business Council for Sustainable Development provides a definition: “Selected waste and by-products with recoverable calorific value can be used as fuels in a cement kiln, replacing a portion of conventional fossil fuels, like coal, if. b. Municipal solid waste consists of solid materials discarded by homes, office buildings, real stores, restaurants, schools, hospitals, prisons, libraries, and other commercial and institutional facilities. c. Non-Municipal solid waste includes from agriculture, mining and industry.

With the national focus on energy, the combustible fraction of urban refuse is being extensively considered as a fuel supplement for coal in the generation of heat and power.
The objective of these analytical studies by the Bureau of Mines was to determine the concentration of major, minor, and trace elements in the combustible fractions.

This research was conducted as part of the U.S. Department of the Interior, Bureau of Mines program to recover metals, glass, and a combustible fraction from municipal solid waste (MSW).
The combustible fraction of municipal solid waste is an important fuel supplement for meeting part of our national energy needs. This paper discusses the ongoing characterization program of municipal solid waste conducted by the Bureau of Mines in providing some of the essential data required to evaluate the possible environmental impact of using refuse-derived fuels.

Introduction. The final disposal of Municipal Solid Waste (MSW) is still a problem in many countries, including European countries. The increasing price of raw materials as well as the lack of space for new landfills, the problems arising from leachate and the restrictions imposed by the European regulations mean that a number of waste strategies have been produced and are awaiting Cited by: Nevertheless, it is apparent that the variability of trace metal content in solid waste is quite broad.

Christensen Department of. Incineration of sewage sludge (SS) in waste incinerators is one of the main ways of SS disposal. In order to reuse the incineration bottom slag, chemical speciation and environmental risk of heavy metals of bottom slag during co-combustion of municipal solid waste (MSW) and SS should be evaluated.
This research was conducted as part of the U.S. Department of the Interior, Bureau of Mines program to recover metals, glass, and a combustible fraction from municipal solid waste (MSW).
The objective of this analytical study was to determine the concentration of antimony, arsenic, and mercury in samples taken from various sampling areas in the Bureau of Mines raw refuse recycling plant and to co.
If the total MSW is burned, as in municipal incinerators, the emitted metals may come from one or both of the two major components of MSW--the combustible fraction (paper, cardboards, plastics, fabrics, etc.) and/or the noncombustible fraction (ferrous metals, nonferrous metals, glass, ceramics, etc.).

Introduction. It is clear that chlorine (Cl) and sulfur (S) in municipal solid waste (MSW) are sources of acidic pollutants during combustion, and are also the key elements in the formation of chlorinated organic compounds, e.g. dioxins (Tuppurainen et al., ; Gullett et al., ).Chlorine is essential for the formation of those compounds, while, in contrast the reductive property of Cited by: 2.

[Pittsburgh, Pa.: Dept. of the Interior, Bureau of Mines, (OCoLC) Gasification of municipal solid waste (MSW) is an attractive alternative fuel production process for the treatment of solid waste as it has several potential benefits over traditional combustion of MSW.
Syngas produced from the gasification of MSW can be utilized as a gas fuel being combusted in a conventional burner or in a gas engine to utilize the heat or produce by: 2. The contribution of this chapter is to deepen and widen existing knowledge on municipal solid waste (MSW) management by analyzing different energy recovery routes for MSW.
The main aspects related to the composition of waste are addressed, as well as the technological routes for thermochemical and biochemical energy usage. Within the thermochemical route, incineration is currently the most Author: José Carlos Escobar Palacio, José Joaquim Conceição Soares Santos, Maria Luiza Grillo Renó, Juarez C.
The composition of municipal waste in western Eu-rope (in ) is given in Figure 1 and can be separated into three parts: an organic fraction that can be composted, a combustible fraction mainly composed of plastics and paper, and a non-combustible fraction of metals, minerals, etc.
