The work aimed at determination of calorific value of municipal solid waste in Enugu, Nigeria and its potential for electricity generation. Random truck sampling was used according to American Society of Test and Material (ASTM) in the collection of samples at Ugwuaji landfill site, Enugu, Nigeria and calorific value was determined using oxygen bomb calorimeter. Enugu has a present population of 882,178 and the amount of municipal solid waste generated in Enugu was estimated to be 420 tonnes daily and this resulted in waste generation rate of 0.48kg/capita/day. The average composition of the municipal solid waste was 39% putrescible, 11% paper, 21% plastics, 5% textile, and 2% metal, 3% glass and 19% others. The average moisture content Volatile... |

This study was aimed at assessing the techno-economic potential of municipal solid waste (MSW) generated in Kampala City for electricity production through gasification. The quantity, characteristics and gasification parameters were determined. In addition, the gasifier- engine system components were sized, and an economic analysis was conducted to obtain the net present value (NPV) and the payback period. This study found that 523 t/d of MSW is collected in Kampala City. The biomass component of MSW was found to be 459.5 t/d with moisture content of 71.09% on as-received basis. The physical characteristics of the gasified biomass included 11.8% moisture content, 88.2% total solids, 25.9% ash content and 57.7 kg/m3 bulk density. The resulting normalized... |

In Latin Americ a, the most accepted disposal systems for Municipal Solid Waste (MSW) are landfills, which nowadays have low rates of stabilization. The objective of this study was to develop design criteria for sanitary landfills which lead to a reduction in the stabilization times of MSW, based on experiment results obtain from a pre-pilot scale operation of two sanitary landfills (0.5 Ton), one with recirculation of leachates treated in an anaerobic digester and the other with recirculation of untreated leachates. This was complemented by another pilot scale sanitary landfill (1440 Ton) with recirculation of leaches treated in an anaerobic filter, and additionally by a computer simulation of leachate generation through the water balance of a theoretical... |

As traditional methods of municipal solid waste management (MSWM) become increasingly expensive due to increased regulation, many local governments are considering cooperation as a waste management strategy. A theoretical model is used to specify a partial observability probability model to analyze the decision Tennessee counties made to form either a single-county solid waste region or a multi-county region. We find that, while economies of scale may be a factor in the consolidation decision, similarities and differences between counties in current individual provision levels of solid waste services, ability to pay for services, and expectations for future solid waste service demands are statistically more important. |

Most of the United States have laws mandating the recycling of municipal solid waste (MSW). In order to comply, municipalities recycle quotas of materials, without regard to fluctuating prices. An inventory system is proposed that allows municipalities to be sensitive to materials prices as they recycle in accordance with state mandates. A dynamic model is developed; it uses historical secondary material prices as exogenous inputs to minimize the net present value of MSW recycling system cost. The model provides a cost-effective method for municipalities to achieve their MSW recycling targets. The savings is approximately $1.43 per ton of MSW generated based on total MSW management costs of $13.5 per ton. The model also allows one to investigate the... |
