I can’t specifically comment on the significance of testing, but any methodology resulting in reduced fugitive emissions is worth it in the long term! Those emissions contribute massively to the final CI for each project and the difference of couple g CO2e of CI reduction is worth exploring maximizing your fugitive system efficiency!

Fugitive emissions monitoring around the mechanical plant is quite rare in our experience. We have some experience with state or federal EPA folks looking at US EPA Method 21 type monitoring and corresponding LDAR plans; though that is not very common.

Seen lots of discussion about residual methane potential of digestate in open manure-style digestate ponds, but generally emissions have not been well quantified from what we’ve seen. Lots of specific examples, some from farms in Europe too, but surprisingly little to inform food waste AD digester operations in the United States.

In our webinar yesterday, one of the speakers mentioned that there is a new study coming in Europe on biogas emissions plants but the problem with it that the approach is outdated. I have an impression that the lack of proved methodology can be hurtful for biogas industry.
