More than 20 biogas plants started working in recent time in Latvia. There is need to investigate the suitability of various biomass for energy production. This paper shows results from the co-fermentation of waste water sludge with milk processing whey and different plant biomasses. The co-fermentation process was investigated for biogas production in 50 l digesters, operated in continuous mode at temperature 38±1.0 deg C. The average methane yield per unit of volatile solids added (VS) from co-fermentation with young willow was 115 l·kgVSaE-1 and the average methane (CH4) content was 51.81%. The average methane yield from co-fermentation with chopped barley straw was 284 l·kgVSaE-1 and the average methane content was 61.47%. All investigated wastes and plants have good biogas yields, and can be successfully cultivated for energy production under agro ecological conditions in Latvia.
