“…Ham and Barlaz 79 suggested that many landfills appear to produce gas according to zero-order kinetics, at least during periods of the most active gas generation. They cited the production of approximately the same amount of gas from full-scale 72 Ghosh et al 73 Sykes 190 Mueller and Mancini 148 Ghosh and Klass 85 Eastman and Ferguson 58 Matsumoto et al" 7 Yaguchi 213 Gujer and Zehnder 78 Lindgren 108 McCarty""" 9 Andrews and Graef 8 Lawrence 89 Ghosh and Pohland 72 Cappenberg 32 Mueller and Mancini 1 " Van Den Berg 205 Kaspar 81 Smith and Mah 1B2 Ghosh and Klass" Zinder and Mah 22 » Lettinga et al 1M Hartman 62 Pol et al 164 Lindgren 108 landfills as a support to this suggestion. Such kinetics may be valid when factors other than substrate availability limit the decomposition rate.…”

Sanitary landfills remain an attractive disposal route for municipal solid waste, because, in most cases, it is more economical than other alternatives such as incineration and composting. Although the composition of solid waste may very substantially with location and time, organic materials constitute the vast majority of this waste. Organic materials are susceptible to microbial decomposition that result in gas and heat generation within the landfill. The migration of gas away from the landfill boundaries and their release into the surrounding environment, present serious environmental concerns at both existing and new facilities. Mathematical models have been used widely to evaluate gas and heat generation and transport processes in landfills. This article presents a critical review of models designed to simulate biological, chemical, and physical processes responsible for the generation and transport of gas and heat in landfills.

“…Even when H , Q and R are known precisely the system (eqns (I), (2) and ( 3 ) ) is very difficult to solve for a single solute, and if several interacting compounds are present then the extended set of equations becomes still harder. In view of this complexity and the difficulty of interpreting the results of a full numerical solution it was decided to verify the biochemical relations before introducing spatial variability.…”

“…By re-circulating leachate and adding water, decomposition rates can be increased, making methane recovery more economical. These processes also compact waste further increasing the operational capacity of the landfill (Hoeks, 1983;Barlaz et al, 1990). Municipal solid waste landfills and Methane-recovery landfills are the top humancaused source of methane in our atmosphere.…”

“…Landfill Processes: Biodegradation Processes, Landfill Gas Production/Emission from MSW The greenhouse gases emissions related to waste deposits are mainly due to methane (CH 4 ) and carbon dioxide (CO 2 ) present in the biogas produced by anaerobic bacteria using as carbon source the biodegradable carbon contained in the waste (Hoeks, 1983). Organic materials (derived from living organisms) produce methane in landfills when they decompose without oxygen (anaerobic), under tons of garbage (Barlaz et al, 1990).…”

“…Municipal solid waste (MSW) contributes to greenhouse gas emissions through decomposition and lifecycle activities/ processes (Farguhar and Rovers, 1973). The greenhouse gases emissions related to waste deposits are mainly due to methane (CH 4 ) and carbon dioxide (CO 2 ) present in the biogas produced by anaerobic bacteria using as carbon source the biodegradable carbon contained in the waste (Hoeks, 1983;Barlaz, Ham & Schaefer, 1990). In particular the disposal of waste in landfills generates methane that has high global warming potential (Yesiller, Hanson and Liu, 2005).…”

The rising levels of greenhouse gases (GHGs) in the Earth's atmosphere have the potential to cause changes in our climate. Some of these emission increases can be traced directly to solid waste. Landfills are among the largest emitters of carbon dioxide and methane, the key GHGs. Thus, effective mitigation of these emissions through formalization of waste reduction into the waste management system to reduce land filling could provide environmental benefits of reducing the adverse impacts of climate change. This paper therefore proposes waste prevention and recyclingjointly referred to as waste reduction as better and most potent strategies for the management of solid waste and for reducing greenhouse gases and calls on both the government and private agencies to check or control the increasing pollution or abuse of the environment by enforcing compliance with the laid out Policies, Pronouncements, Regulations and enacted Legislation especially in the developing countries. The study concludes that by choosing to prevent waste and recycle, less waste will be generated, the need for landfill will be minimal, energy demand will decrease, fewer fossil fuels will be burned and less methane and carbon dioxide will be emitted to the atmosphere which helps to curb climate change.
