Cogas
company is involved in the recovery of Landfill Gas at three places in
the Netherlands:
DELDEN,
VASSE and COLLENDOORN.
In 1999
there was an international contact with Peru in South America for
assistance with a Landfill Gas Project near Lima, the capital of
Peru. Problems with financial support from the local authorities, were cause to stop that project.
Because of the high contents of methane in the landfill gas, it is a 20 times higher contribution to the greenhouse gases if it can escape freely. So the use of the gas for fuel purposes is a good thing to our environment. Economic recovery depends on the amount of retractable gas. How do we know how many cubic meters of gas a landfill produces?
During
my work on the above mentioned projects I developed a method for the calculation
of the amounts of biogas that possibly can be extracted from a regular
landfill.
As
landfill gas is generated from organic compounds in the waste, I tried
to investigate the composition of the refuge.
From sorting tests and publications I composed a scheme for moderate composition in rural landfills and calculated the Specific Gas Production (in cubic meters per tonne refuse per year).
