Landfill Scheme
Landfill gas
These fuel gases are produced by the conversion of
liquid or solid organic substances by micro-organisms.
Like associated petroleum gas, they are characterized
by a medium to high methane content and the consti-
tuents N and CO . However, as this gas emanates from

highly heterogeneous substances, special care must
be taken with regard to trace substances and
impurities.
How does it work
Municipal waste contains about 150 to 250 kg of
organic carbon per ton. These substances are
biologically degrad-able and are converted by
microorganisms into landfill gas. Stable, anaerobic
methane fermentation begins one to
two years after the waste is deposited in the landfill
