More than 20 biogas plants started working in recent time in Latvia. There is need to investigate the suitability of various biomasses 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°C. The average methane yield per unit of dry organic matter added (DOM)...
