Default values of 0.4 for methane correction factor (MCF), 0.77 for fraction of degradable organic carbon dis- similated (DOCF), and zero for oxidation factor (OX) and recovered methane (R) were used for computation in this study as per the IPCC Tier I method (IPCC, 1996; IPCC Good Practice Guidance, 1996; Kumar et al., 2004b).

Potential for control
The trapping of methane from strong sources of livestock manure methane, such as slurry tanks, has already proved a very successful way of reducing methane emissions to the atmosphere from this source. The recovered methane, often called 'biogas’, can be simply flared off as carbon dioxide or can potentially be used as a fuel.

Relative overpressure of methane
R=(Pg -Ph /Ph)

The relative overpressure of methane R is given by a relationship:
R = (Pg –Ph )/Ph

Lastly, Philips has built a throne for the source of the methane powered home. The Filtering Squatting toilet separates liquid and solid waste, filtering the first to water to help grow plants and channeling the other to the home system to convert to methane. It utilizes the 1 liter flush toilet technique, consuming no energy at all.
