Biogasproduction in Sweden
Co-digestion plants Wastewater treatment plants Upgrading plant Source: Energigas Sverige
Co-digestion plants 36 (963 GWh) Wastewater treatment plants 138 (727 GWh) Farm plants 44 (56 GWh) Industrial plants 6 (143 GWh) Land fil 55 (141 GWh)
Producing in total ≈2 TWh biogas
Upgrading plants 70 plants in total

Main targets
- further improve the environmental performance of the
biogas system
- give plant owners help in performing a structured
inventorying of their plant to detect emissions
- give plant owners better knowledge about the size of the
emissions from their plant
- identify and reduce any emissions
- give the biogas industry better information and thereby
greater credibility in relation to emissions.

EgMet consists of two main parts
1) Systematic leak detection and avert found leaks 2) Emission measurement at emission points with suggestions for reduction
- Regular and systematic leak detection and a more extensive leak
detection once a year (inhouse)
- Quantafiying emissions every three years (executed by external
and independent part)
- Report includes quantification records and deviation reports for
each spoted emission point and provides suggestions for reducing emissions.
- The quantifications are then sent to the administrative office by
the plant
