Abstract
The biogas and energy potential from different biomasses is needed to be evaluated, including manure, wastewater sludge, energy plants, and food und biofuel processing wastes in Latvia. Energy crops growing on unused agricultural area are the most important biomass feedstock and its share is around 88% of whole biogas potential in Latvia. Biogas output from different biomass was investigated in laboratory scale digesters operated at 38 deg C. Biomass mixed with inoculums (fermented cow manure) was investigated for biogas production in sixteen digesters, operated in batch mode at temperature 38±1.0 deg C. The average methane yield from old grass silage was 248 l•kgDOMaddE-1 and the average methane content was 48.9%. The average methane yield from chopped oats was 303 l•kgDOMaddE-1 and the average methane content was 63.1%. The average methane yield from dry fraction of pigs manure was 342 l•kgDOMaddE-1 and the average methane content was 54.53%. All the investigated biomasses can be successfully cultivated for energy production in Latvia.
