Methane emissions: monitoring and reduction

Thanks - interesting point

According to Global Water Intelligence's Mapping water's climate footprint, methane accounts for 25% of GHG emissions from waste water and sludge emissions.

At the same time, methane emissions detection and monitoring technologies are being developed
cordis.europa.eu/project/id/722479

I have uploaded to the library Klara Westling's presentation on 'Systematic measures in Sweden to reduce leakage of methane from biogas production and upgrading' and the 'Climate calculation tool' excel file and user manual.
Thank you Klara.

Methane emissions and the Taxonomy, please see here – and below: eur-lex.europa.eu/legal-content/EN/TXT/P...X:32021R2139&from=EN
This delegated act was decided in autumn 2021 and is a Taxonomy requirement since 1st January 2022

5.6. Anaerobic digestion of sewage sludge
Description of the activity

Construction and operation of facilities for the treatment of sewage sludge by anaerobic digestion with the
resulting production and utilisation of biogas or chemicals.
The economic activities in this category could be associated with several NACE codes, in particular E37.00 and
F42.99 in accordance with the statistical classification of economic activities established by Regulation (EC)
No 1893/2006.

Technical screening criteria
Substantial contribution to climate change mitigation
1. A monitoring and contingency plan is in place in order to minimise methane leakage at the facility.

5.7. Anaerobic digestion of bio-waste
Description of the activity
Construction and operation of dedicated facilities for the treatment of separately collected bio-waste (215) through
anaerobic digestion with the resulting production and utilisation of biogas and digestate and/or chemicals.
The economic activities in this category could be associated with several NACE codes, in particular E38.21 and
F42.99 in accordance with the statistical classification of economic activities established by Regulation (EC)
No 1893/2006.

Message carried over from Anders Finnson from the previous chat...:
To reduce methane emissions from the production of biogas at digesters at waste water treatment plants and at digesters for organic waste, the Swedish operator organisations for waste water (Svenskt Vatten) and waste (Avfall Sverige) have published this report: iwa-network.org/wp-content/uploads/2015/...ethane-Emissions.pdf

Measurements of emissions and monitoring of methane are essential for the development of robust emission inventories. Field measurement of emissions from various sectoral sources can provide an improved understanding of processes that lead to emissions, which contributes to the development of process-based emission models as well as regional- and urban-scale mitigation strategies.
