Abstract:
Subsurface temperature is a critical indicator for the identification of the risk associated with subsurface fire hazards in landfills. Most operational landfills in the United States (US) have experienced exothermic reactions in their subsurface. The subsurface landfill area is composed of various gases generated from chemical reactions inside the landfills. Federal laws in the US mandate the monitoring of gases in landfills to prevent hazardous events such as landfill fire breakouts. There are insufficient investigations conducted to identify the causes of landfill fire hazards. The objectiv

Abstract:
The main components of landfill gas are methane and carbon dioxide. Emissions of methane, a strong greenhouse gas, can be minimized by in situ oxidation in the bioactive cover layer. Typically, organic-rich porous materials such as compost are used for this process. In this study, the material for a biocover was obtained from the same landfill by landfill mining. The objective was to study the spatial distribution of gases and the efficiency of methane degradation in the biocover. The methane and carbon dioxide emissions were measured at 29 measuring points six times on the surface and once at

Abstract:
This review evaluates the current Landfill Gas (LFG) utilisation technology across Africa and gives general overview on the global context. With the increase in global Municipal Solid Waste (MSW), the world has embraced landfilling to be its major way of MSW management. About 85% of the world’s MSW is deposited in landfills. This has brought increased concerns of gases emitted from landfill sites. These gases have contributed enormously to the global anthropogenic Greenhouse Gas (GHG) emission which are detrimental to the world’s environmental media. Although significant progress has been made

Pilot-scale investigations on the fate and potential effects of disposable diapers codisposed with shredded municipal refuse were conducted using simulated landfills operated under leachate containment and recycle conditions. Carbon fourteen(14C)-labelled absorbent gelling material (AGM) was used to detect the possible loss of the diaper polymer to the gases and liquids generated during the various stages of landfill stabilization. Only a small quantity (<3%) of the total 14C appeared in either the leachate or gas phases. This indicated only minor degradation of the 14C-labelled AGM to

Landfill gas (LFG) is a mixture of gases mainly CH4 and CO2 which are the most problematic of the greenhouse gases (GHGs) due primarily to their highest rate of accumulation in the environment. These two main GHGs are emitted from most landfills in developing countries. As a mitigation measure, the gases can be collected and utilized as renewable energy source. This research therefore aimed at planning the utilization of LFG for renewable energy production using linear programing approach executed in general algebraic modeling system (GAMS) and applied to Seelong landfill in Johor, Malaysia as

Biogas calorie efficiency is proportional to the concentration of CH4 in biogas. However, the quantity and quality of biogas that produced in landfill depend on the characteristic and density of domestic solid waste in landfill.

Abstract:
Municipal solid waste (MSW) is an energy source that should not go untapped or unutilized. The waste must be properly utilized through combustion, anaerobic digestion, and landfill gas acquisition, as it represents material and energy content. This will reduce the effects of global warming, which is as a result of high concentration of carbon dioxide, methane, and other greenhouse gases (GHGs), in the atmosphere. This chapter focuses on the technologies for solid waste management and the thermodynamics involved in the process for sustainable and cleaner energy. The equations presented represent the thermal efficiency, conversion efficiencies, as well as possible work that can be derived from a power plant utilizing MSW as fuel. It is important that countries in Sub-Saharan Africa vigorously pursue sustainable waste management technologies, especially recycling and landfilling, while exploring and investing in waste-to-energy technologies that will perform optimally using the composition of the waste in Sub-Saharan Africa in the design of the waste-to-energy technology.

Landfill gases and biogases are low Btu gases which were, until recently, underutilized.

The main portion of landfill gas or biogas is comprised of methane and carbon dioxide with some other gases in small proportions. Release of methane directly to the atmosphere causes about 21 times global warming effects than carbon dioxide. Thus landfill gas is flared often,
