Support for biogas production in Latvia was decreased. There is an urgent need to
i
nvestigate the suitability of various inexpensive renewable biomass resources for energy
production. Also, itis necessary to explore the possibilities to improve the anaerobic fermentation
process with the help of various catalysts. Biocatalyst Metaferm pr
oduced in Latvia was used in
previous studies with other biomass and showed increase in biogas and methane production. The
article shows the results of studies on biogas (methane) production from chopped fresh Common
nettle (
Urtica dioica
) and Canadian gol
denrod (
Solidago canadensis
) biomass and effect of
catalyst Metaferm in anaerobic fermentation process. The anaerobic digestion process was
performed in 0.75
L laboratory digesters, operated in batch mode (38
±
1.0
°C, 35 days). The
average specific biogas
or methane production per unit of dry organic matter added (DOM) from
Common nettle was 0.709

Adding of catalyst Metaferm increases methane yield from chopped nettle or Canadian goldenrod
by 1.2% or 3.4% respectively. All investigated biomass resources c
an be used for methane
production.
