Energy efficiency and environmental impact of biogas utilization in landfills
This study investigates the utilization of landfill biogas as a fuel
for electrical power generation. Landfills can be regarded as
conversion biogas plants to electricity, not only covering internal
consumptions of the facility but contributing in the power grid as
well. A landfill gas plant consists of a recovery and a production
system. The recovery of landfill gas is an area of vital interest since
it combines both alternative energy production and reduction of
environmental impact through reduction of methane and carbon dioxide,
two of the main greenhouse gases emissions. This study follows two main
objectives. First, to determine whether active extraction of landfill
gas in the examined municipal solid waste sites would produce adequate
electric power for utilisation and grid connection and second, to
estimate the reduction of sequential greenhouse gases emissions.
However, in order to optimize the designing of a plant fed by biogas,
it is necessary to quantify biogas production over several years. The
investigation results of energy efficiency and environmental impact of
biogas utilization in landfills are considering satisfactory enough
both in electric energy production and in contribution to greenhouse
gases mitigation
