Municipal solid wastes MSWs

Simplified in process terms, RDF involves processing the incoming municipal solid waste (MSW) stream to remove a substantial portion of the noncombustible components, namely aluminum, ferrous, glass and dirt. Various sources list these components in the range as follows ... 

As a fuel, municipal solid waste (MSW) does not compare too favorably with more traditional solid fuels, such as coal. M.SW averages somewhere around 4500 Btu/lb, versus coal at 10,500-13,000 Btu/lb. Flowever, given the current U.S. population of 250 million and the annual generation of waste per person of fifteen hundred pounds, the potential energy content in the annual waste generated in the U.S. alone is comparable to nearly seventy million tons of coal and has the potential to generate over 13,000 MW of electrical power. As of a published report in 1993, 128 facilities were actually in operation, with an additional... 

However, there is one exception to using the TCLP to identify a waste as hazardous. The DC Circuit Court, in Association of Battery Recyclers vs. U.S. EPA, vacated the use of the TCLP to determine whether manufactured gas plant (MGP) wastes exhibit the characteristic of toxicity. As previously stated, the TCLP replicates the leaching process in municipal landfills. The court found that U.S. EPA did not produce sufficient evidence that co-disposal of MGP wastes from remediation sites with municipal solid waste (MSW) has happened or is likely to happen. On March 13, 2002, in response to the court vacatur, U.S. EPA codified language exempting MGP waste from the toxicity characteristic regulation. 

Landfills are the physical facilities used for the ultimate disposal of residual solid wastes in the ground. In the past, the term sanitary landfill was used to denote a landfill in which the wastes were placed in the landfill and then covered at the end of daily operation. Today, sanitary landfill refers to an engineered facility for the disposal of municipal solid waste (MSW), designed and operated to minimize public health and environmental impact. 

Alternative final cover systems, such as the innovative evapotranspiration (ET) cover systems, are increasingly being considered for use at waste disposal sites, including municipal solid waste (MSW) and hazardous waste landfills when equivalent performance to conventional final cover systems can be demonstrated. Unlike conventional cover system designs that use materials with low hydraulic permeability (barrier layers) to minimize the downward migration of water from the cover to the waste (percolation), ET cover systems use water balance components to minimize percolation. These cover systems rely on the properties of soil to store water until it is either transpired through vegetation or evaporated from the soil surface.

Biomass can be a renewable feedstock for methane. Biomass feedstocks for methane production include crop residues, municipal solid waste (MSW), and wood resources. Biomass resources for the production of alcohol fuels are estimated at about 5 million dry tons per day which could provide 500 million gallons of methanol per day. 

Both in the USA and the EU, the introduction of renewable fuels standards is likely to increase considerably the consumption of bioethanol. Lignocelluloses from agricultural and forest industry residues and/or the carbohydrate fraction of municipal solid waste (MSW) will be the future source of biomass, but starch-rich sources such as corn grain (the major raw material for ethanol in USA) and sugar cane (in Brazil) are currently used. Although land devoted to fuel could reduce land available for food production, this is at present not a serious problem, but could become progressively more important with increasing use of bioethanol. For this reason, it is important to utilize other crops that could be cultivated in unused land (an important social factor to preserve rural populations) and, especially, start to use cellulose-based feedstocks and waste materials as raw material. 

Biogas can be obtained from digesting the organic material of municipal solid wastes (MSW). The composition of MSW varies by the somce of waste however, in all cases the major constituents of MSW are organic in nature and the organics accoimts for more than 50% of MSW. The economic exploitation of methane is worthwhile after one year from the start of the landfill operation.

In practice, we have a number of solid fuels, for example biofuels (forest or agricultural derived biofuels), coal, municipal solid waste (MSW) and many others [23]. A fuel bed is composed of varying sizes of solid-fuel particles, also called polydispersed solid-.fuels [15]. The fuel chemistry is different depending on whether it is coal, biofuel or MSW. The fuel bed can be dry or consist of moisture. The fuel physics are for example, particle size distribution, particle shape, particle density and bed permeability. 

The term municipal solid wastes (MSW) is used to describe the wide range of waste materials produced by individual, family, and community activities. The graph shows the approximate composition of the municipal solid waste found in the United States today.
