Thank you Abdul for this! I will try to find my way through these papers!

Update Jan 12: I must say I am still quite confused...i would like to have much more simple explanations. Anyone else on this one?

Ola,  I may be very late to this question (I noted it only now), but it caught my attention as I am also confused with these different terms related to methane potential.

Adding to this confusion, there is another term called: ‘maximum methane producing capacity’ (Bo), mentioned in the IPCC (2006) protocol for estimating methane emissions from livestock manure.

Unit for Bo is: m3 CH4 kg-1 of VS (volatile solids) which is identical to the unit (mL CH4/ g VS) used for ‘biochemical methane potential’.  I feel these both terms refer to the same parameter.  Do you have any comment?  I really appreciate if you could, as I am very interesting to know if these two are the same or closely define the same.

Thanks.

Susantha.

Susantha, I have so far not come across the term you refer to, but I agree that they look the same. I am now in a process of publishing a paper on horse manure as feedstock for anaerobic digestion in which I have discussed this specific problem of a terminology that may be misinterpreted. I will, when appropriate, turn to colleagues in the field for more clarity on the subject.

Thanks,

Ola

Ola, Thanks for the comment. The term ‘maximum CH4 producing capacity’ (Bo) is explained in the IPCC (2006) protocol pages 10-41 to 10.43 where it explains the algorithm for estimating CH4 emissions from manure management.  The Chapter name and the link to the document is as follows:

 2006 IPCC Guidelines for National Greenhouse Gas Inventories. Chapter 10. Emissions from livestock and manure management.

http://www.ipcc-nggip.iges.or.jp/public/2006gl/pdf/4_Volume4/V4_10_Ch10_Livestock.pdf

From a closer look at this parameter and the ‘Biological CH4 potential’, I thought they both define the same.  Any way...I am further reading papers on this subject to get a better understanding and looking forward to read your paper.

Best regards.

Susantha.
