Organic waste is characterized above all by its composition of dry matter (MD) and volatile matter (MV)
The Methane Potential is the volume of methane
during anaerobic degradation in the presence of bacteria of a sample
initially introduced, expressed under Normal conditions of
Temperature and Pressure (CNTP: 0°C, 1013 hPa).
The bio-degradation is estimated starting from the production of methane biogas obtained during the tests compared to the theoretical maximum production.
The protocol is based to the measure of the production of methane by a closed engine in which are put in contact a known quantity of the sample to test and a known quantity of anaerobic micro-organisms, the latter being placed under favourable conditions for the degradation of the sample.
You will find in the table bellow for some waste its potential of methane production (in m3 of methane per ton of raw material):
(m3 CH4/Ton of raw material)
|Liquid bovine manure||20|
|Contents of paunch||30|
|Shearing of lawn||125|
|Lubricate from slaughter-house||180|
