This investigation was conducted to evaluate the influence of waste placement practices on the engineering response of municipal solid waste (MSW) landfills. Waste placement conditions were varied by moisture addition to the wastes at the time of disposal. Tests were conducted at a California landfill in test plots (residential component of incoming wastes) and full-scale active face (all incom...

The management of Municipal Solid Waste (MSW) in Nigeria and most developing countries has remained a major public health challenge, thus creating the need for reliable and environmentally-acceptable alternatives. This study focuses on composting assessment as a viable recovery alternative for MSW in six States of Southwest Nigeria, namely: Ekiti, Osun, Ondo, Ogun, Oyo, and Lagos. Extensive lit...

Most of the municipal solid waste (MSW) in developing countries ends up landfills. For example, more than 95% MSW generated Latin America is disposed some type landfill. Factors such as high organic compositions, low recycling rates and poor control over disposal sites greatly increase environmental impacts associated with management this region, resulting increased emissions greenhouse gases (...

Municipal solid waste (MSW) is biodegradable in landfills under anaerobic conditions. The evolution of the hydro-biochemical-mechanical (HBM) processes during degradation investigated first through experiments and subsequently modelling. Three well-characterised MSW specimens from US landfill sites with significantly different compositions ranging ‘waste-rich’ to ‘soil-rich’ were degraded large...

The municipal solid waste (MSW) remains a great challenge in most cities of developing countries, as the majority generated is either not collected or dumped open uncontrolled non-engineered landfill sites, creating significant pollution due to leakage leachate surrounding environment. In complete transition zero-landfill scenario less likely happen near future various socio-economic challenges...

Abstract Average biodegradation rate of newly filled municipal solid waste (MSW) in landfills is relatively fast, and the landfill gas produced by new MSW can cause great variations pressure. To predict pressure distribution layer, a one-dimensional transport model established this study. The following factors are considered model: (1) variation permeability with depth; (2) anisotropy ratio per...

results the modeling results showed that for the gas recovery starting in 2000 and 2015, the power generation would be 2,354 and 830 mw, respectively. in fact, the 15-year difference in gas extraction made a 200% difference. based on the results, from 2000 to 2100, 558 m3/hour of methane would be extracted, which would be equivalent to 2,354 mw energy. subsequently, the emission of 93,721,837 t...

This study was conducted to investigate the quality of groundwater affected due municipal solid waste (MSW) used as a landfill. To assess impacts, 13 samples were collected from dumping sites (SWDS) and safe (SS). Groundwater analyzed for pH, turbidity, electrical conductivity (EC), total hardness (TH), Cl?, Ca+2, K+1, NO?2, NO?3, SO4?2; heavy metals such Pb, Cr, Mn, Cu, Ni, Zn, Cd, Fe; biologi...
